Description
본 발명은 흙콘크리트용 시멘트 조성물, 이를 포함하는 흙콘크리트 및 이를 이용한 흙콘크리트의 포장방법에 관한 것이다. The present invention relates to a cement composition for earth concrete, an earth concrete comprising the same, and a method for paving earth concrete using the same.
국내를 비롯한 각국들은 지금까지 모래와 자갈을 시멘트에 혼합한 콘크리트를 건축소재로 사용해왔다. 그러나 골재류 채취가 환경 파괴의 주범으로 등장하고 또 골재류가 바닥난 상태에서 더 이상 이러한 골재 위주의 콘크리트를 사용할 수 없는 한계에 이르렀다. 이에 가장 흔하고 인류의 건강에 최적의 요소로 등장하고 있는 흙을 사용할 수 밖에 없게 되었다. 그러나 일반적으로 흙은 콘크리트와 잘 융합되지 않는다. 이러한 특수성을 화학적으로 가능하게 한 것이 흙콘크리트이다. Many countries including Korea have used concrete mixed with sand and gravel to cement as a building material. However, aggregate collection has emerged as the culprit of environmental degradation, and when aggregates have run out, they have reached the limit of no longer using such aggregate-oriented concrete. Soil is the most common and appears to be the optimal element for human health. In general, however, soil does not fuse well with concrete. It is earth concrete that has made this specificity chemically possible.
일반적으로 흙콘크리트를 사용한 흙포장의 시공 시에는 포장대상 흙의 습윤밀도나 함수율과 같은 특성에 따라 흙콘크리트의 물성이 매우 열악한 상태로 포장되는 문제점을 가지고 있다. In general, the construction of soil packaging using soil concrete has a problem that the physical properties of the soil concrete is paved in a very poor state depending on the properties such as wet density and moisture content of the soil to be packaged.
종래 흙콘크리트는 흙의 다양한 특성이 반영되지 않아, 흙 중에 포함된 유기물과 미세한 흙 입자가 흙콘크리트의 경화 특성을 방해하여 강도 물성을 저해함으로써 우수기의 빗물에 의한 투수로 인하여 수분 팽윤현상이 발생하고, 이러한 현상에 의해 시멘트 경화체의 미세공극을 팽창시키는 문제점이 발생한다. 또한, 이러한 문제점은 겨울철 동결융해 현상으로 이어져 흙콘크리트의 급격한 성능저하로 인해 장기 내구년한을 감소시켜 대부분 경우에 3년이 경과할 시에 포장도로로서의 기능을 상실하는 문제점이 있다. Conventional soil concrete does not reflect the various properties of the soil, the organic matter and fine soil particles contained in the soil interferes with the curing properties of the soil concrete to inhibit the strength properties, water swelling phenomenon occurs due to the permeation by rainwater of rainwater In addition, this phenomenon causes a problem of expanding the micropores of the cement hardened body. In addition, this problem leads to a freeze-thawing phenomenon in winter, due to the drastic deterioration of the soil concrete, reducing the long-term end-of-life limit in most cases loses its function as a pavement.
또한, 시공 후 일축압축강도가 느리게 증가하여, 동결융해 및 우수기의 수분 팽윤현상 등으로 초기에 안정된 포장지반을 조성하지 못하는 문제점을 가지고 있다. In addition, the uniaxial compressive strength is increased slowly after construction, there is a problem that can not form a stable paving ground initially due to freezing thawing and water swelling phenomenon of the rainy season.
본 발명의 목적은 친환경적이고, 신속하고 안정된 강도 발현이 가능하며, 동결융해에 의한 내구년한을 반영구적으로 현저히 증가시킨 흙콘크리트용 시멘트 조성물을 제공하는 것이다.It is an object of the present invention to provide a cement composition for earth concrete, which is environmentally friendly, enables rapid and stable strength development, and has a semi-permanent remarkably increased endurance life due to freezing and thawing.
본 발명의 다른 목적은 상기 흙콘크리트용 시멘트 조성물을 포함하는 흙콘크리트를 제공하는 것이다. Another object of the present invention is to provide an earth concrete comprising the cement composition for earth concrete.
본 발명의 또 다른 목적은 상기 흙콘크리트를 이용한 포장방법을 제공하는 것이다. Still another object of the present invention is to provide a packaging method using the soil concrete.
다만, 본 발명이 이루고자 하는 기술적 과제들은 이상에서 언급한 과제들로 제한되지 않으며, 또 다른 기술적 과제들은 아래의 기재로부터 평균적 기술자에게 명확하게 이해될 수 있을 것이다.

이하, 본 발명의 구현예를 상세히 설명하기로 한다. 다만, 이는 예시로서 제시되는 것으로, 이에 의해 본 발명이 제한되지는 않으며 본 발명은 후술할 청구범위의 범주에 의해 정의될 뿐이다. Hereinafter, embodiments of the present invention will be described in detail. However, this is presented as an example, by which the present invention is not limited and the present invention is defined only by the scope of the claims to be described later.
본 발명의 일 구현예에 따르면, 3종 조강 시멘트 45 내지 55중량%, 생석회 5 내지 15중량%, 알루미나시멘트 15 내지 25중량%, 불산석고 10 내지 15중량%, 수산화리튬 0.1 내지 0.5중량%, 규불화나트륨 0.1 내지 3중량%, 카바이트 0.1 내지 3중량%, 및 플루오린화칼슘 1 내지 5중량%을 포함하는 흙콘크리트용 시멘트 조성물을 제공한다. According to one embodiment of the present invention, three kinds of crude steel cement 45 to 55% by weight, quicklime 5 to 15% by weight, alumina cement 15 to 25% by weight, gypsum fluorite 10 to 15% by weight, lithium hydroxide 0.1 to 0.5% by weight, It provides a cement composition for soil concrete comprising 0.1 to 3% by weight of sodium silicate, 0.1 to 3% by weight of carbide, and 1 to 5% by weight of calcium fluoride.
상기 3종 조강 시멘트는 조강 시멘트로서 흙콘크리트의 응결을 촉진하는 효과를 가지며, 응결초기에 경화속도를 증가시켜 다양한 흙의 물성에 대하여 초기에 안정된 경화를 시키기 위한 역할을 한다. 상기 3종 조강 시멘트의 함량은 흙콘크리트용 시멘트 조성물 100중량%를 기준으로 하여 45 내지 55중량%이다. 상기 3종 조강 시멘트의 함량이 45중량% 미만인 경우 열악한 경화조건(경화토의 함수률, 유기물질함유 등)에서 초기에 안정한 강도발현이 어려우며 55중량%를 초과하는 경우 경화속도의 증가로 초기 작업시간의 확보와 장기압축강도를 저하시켜 내구년한을 저하시키는 문제점이 있다. The three kinds of crude steel cement has the effect of promoting the condensation of the soil concrete as a crude steel cement, and serves to increase the curing speed at the initial stage of the solidification to initially stabilize the various properties of the soil. The content of the three types of crude steel cement is 45 to 55% by weight based on 100% by weight of the cement composition for soil concrete. When the content of the three types of crude steel cement is less than 45% by weight, it is difficult to express stable strength initially under poor curing conditions (water content of hardened soil, organic material, etc.), and when the content exceeds 55% by weight, the initial working time is increased by the curing speed. There is a problem of lowering the life expectancy by lowering the long-term compression strength and securing.
상기 생석회는 흙에 포함된 함수량의 제어를 통하여 골재로서의 시멘트 입자와의 혼합을 용이하게 하며 또한, 생석회가 수화하여 생성된 수산화칼슘은 콘크리트의 충진제로서 보다 수밀성을 향상시키는데 기여하는 역할을 한다. 상기 생석회의 함량은 흙콘크리트용 시멘트 조성물 100중량%를 기준으로 하여 5 내지 15중량%가 바람직하다. The quicklime facilitates mixing with the cement particles as aggregate through the control of the water content contained in the soil, and the calcium hydroxide produced by the quicklime is hydrated serves to improve the water tightness as a filler of concrete. The quicklime content is preferably 5 to 15% by weight based on 100% by weight of the cement composition for soil concrete.
상기 생석회의 함량이 5중량% 미만이면 경화토의 탈수효과가 미비하여 초기발열로 인한 수화반응속도를 향상시키기 어려우며, 15중량%를 초과하면 급격한 탈수와 발열반응으로 인한 흙콘크리트의 슬럼프를 저하시켜 시공성을 저하시키는 문제가 있다. When the content of quicklime is less than 5% by weight, it is difficult to improve the hydration reaction rate due to the initial heat generation due to insufficient dehydration effect of the hardened soil. When the content of the quicklime exceeds 15% by weight, the slump of soil concrete due to rapid dehydration and exothermic reaction is lowered. There is a problem of lowering.
상기 알루미나시멘트는 내화학성이 뛰어나고 경화시 치밀한 경화체의 조직을 형성하여 고강도성을 발현시키고, 초기 경화를 촉진시키며 흙의 미립자와 유기물에 의한 콘크리트의 수경성 저하를 방지하고 또한, 강한 분산성 및 흙과의 응집성을 강화시켜주는 역할을 한다. 상기 알루미나시멘트의 함량은 흙콘크리트용 시멘트 조성물 100중량%를 기준으로 하여 15 내지 25중량%가 바람직하다. 상기 알루미나시멘트의 함량이 상기 범위 내에 있는 경우 장기 안정성을 유지하는데 큰 효과를 얻을 수 있다. The alumina cement has excellent chemical resistance and forms a structure of dense hardened body upon hardening to express high strength, promotes initial hardening, prevents decrease of hydraulic properties of concrete by fine particles and organic matter of soil, and also has strong dispersibility and soil and It enhances the cohesion of The content of the alumina cement is preferably 15 to 25% by weight based on 100% by weight of the cement composition for soil concrete. When the content of the alumina cement is in the above range can be obtained a great effect in maintaining long-term stability.
또한, 일반적으로 알루미나 시멘트의 과다사용은 동결융해에 대한 저항성을 감소시키는 문제점이 있으므로 초기안정성과 동결융해의 저항성을 고려할 때 알루미나시멘트의 적정사용량은 15 내지 25중량%가 바람직하다. In addition, in general, the excessive use of alumina cement has a problem of reducing the resistance to freezing and thawing, so considering the initial stability and resistance to freezing and thawing, an appropriate amount of alumina cement is preferably 15 to 25% by weight.
상기 불산석고는 알루미나시멘트의 경화시 보조제로서 경화촉진 및 고강성을 발현하는 역할을 한다. 상기 불산석고의 함량은 흙콘크리트용 시멘트 조성물 100중량%를 기준으로 하여 10 내지 15중량%가 바람직하다. 상기 불산석고의 함량은 알루미나시멘트의 사용량에 맞게 조절되어야 하며 그 함량이 10중량% 미만인 경우 초속경성의 발현이 난이하여 초기안정성을 확보하기가 어렵고, 15중량%를 초과하는 경우 팽창메카니즘의 작용으로 강도물성의 저하를 초래하는 문제가 있다. The phosphate gypsum serves to promote hardening and high stiffness as an adjuvant when curing the alumina cement. The content of the phosphate gypsum is preferably 10 to 15% by weight based on 100% by weight of the cement composition for soil concrete. The content of gypsum fluorite should be adjusted according to the amount of alumina cement used, and if the content is less than 10% by weight, it is difficult to secure initial stability due to the difficulty of expressing super-hardness, and if it exceeds 15% by weight, it is due to the action of the expansion mechanism. There is a problem that causes a drop in strength properties.
상기 수산화리튬은 흙의 미립자와 유기물에 의한 콘크리트의 경화를 방지하는데 대하여 시멘트의 경화 반응성을 뛰어나게 하고, 알루미나시멘트의 초속경성을 촉진시키기 위한 성분이다. 상기 수산화리튬의 함량은 흙콘크리트용 시멘트 조성물 100중량%를 기준으로 하여 0.1 내지 0.5중량%가 바람직하다. 상기 수산화리튬의 함량이 상기 범위 내에 있는 경우 상술한 수산화리튬의 역할에 따른 효과를 얻을 수 있다. The lithium hydroxide is a component for improving the hardening reactivity of the cement to prevent the hardening of the concrete by the fine particles of the soil and the organic material, and to promote the ultra-fast hardness of the alumina cement. The content of the lithium hydroxide is preferably 0.1 to 0.5% by weight based on 100% by weight of the cement composition for soil concrete. When the content of the lithium hydroxide is within the above range it can be obtained the effect according to the role of the lithium hydroxide described above.
상기 규불화나트륨은 방수성을 가지고 있을 뿐만 아니라 흙콘크리트에 있어 시멘트 입자의 독립경화를 향상시키며 유기물과 미립자로부터 시멘트의 수화물의 생성을 촉진시키는 역할을 한다. 상기 규불화나트륨의 함량은 흙콘크리트용 시멘트 조성물 100중량%를 기준으로 하여 0.1 내지 3중량%가 바람직하다. 상기 규불화나트륨의 함량이 상기 범위 내에 있는 경우 상술한 규불화나트륨의 역할에 따른 효과를 얻을 수 있다. The sodium silicate not only has waterproofness but also improves the independent hardening of cement particles in soil concrete and serves to promote the generation of hydrate of cement from organic matter and fine particles. The content of the sodium silicate is preferably 0.1 to 3% by weight based on 100% by weight of the cement composition for soil concrete. When the content of the sodium silicate is in the above range can be obtained according to the role of the above-mentioned sodium silicate.
상기 카바이트는 물과의 반응에서 급격한 발열반응을 촉진시켜 시멘트경화반응의 방해물질이 존재하는 흙콘크리트의 경화 메카니즘을 원활하게 하는데 매우 중요한 역할을 한다. 또한 계절적으로 온도가 낮은 환경에서도 콘크리트의 시공물성을 확보할 뿐만 아니라 흙의 함수율을 제어하는데도 필수적인 역할을 한다. 상기 규불화나트륨의 함량은 흙콘크리트용 시멘트 조성물 100중량%를 기준으로 하여 0.1 내지 3중량%가 바람직하다. 상기 카바이트의 함량이 상기 범위 내에 있는 경우 상술한 카바이트의 역할에 따른 효과를 얻을 수 있다. The kite plays a very important role in facilitating the rapid exothermic reaction in the reaction with water to facilitate the hardening mechanism of the soil concrete in which the obstacle of the cement hardening reaction is present. In addition, it plays an essential role in controlling the moisture content of the soil as well as securing the construction properties of concrete even in a low temperature environment. The content of the sodium silicate is preferably 0.1 to 3% by weight based on 100% by weight of the cement composition for soil concrete. When the content of the byte is in the above range can be obtained according to the role of the above-described byte.
상기 플루오린화칼슘은 충진제로서의 1차적인 사용목적이 있으며 2차적으로는 시멘트수화물의 내구성을 향상시키는데 그 역할이 있다. 상기 플루오린화칼슘의 함량은 흙콘크리트용 시멘트 조성물 100중량%를 기준으로 하여 0.1 내지 3중량%가 바람직하다. 상기 플루오린화칼슘의 함량이 상기 범위 내에 있는 경우 상술한 플루오린화칼슘의 역할에 따른 효과를 얻을 수 있다. The calcium fluoride has a primary purpose of use as a filler and secondaryly plays a role in improving the durability of cement hydrate. The content of the calcium fluoride is preferably 0.1 to 3% by weight based on 100% by weight of the cement composition for soil concrete. When the content of the calcium fluoride is in the above range can be obtained according to the role of the calcium fluoride described above.

In the present invention, the initial condensation is quickly achieved by including the soil to be packaged in the above-mentioned cement composition for earth concrete, without using aggregates such as gravel or sand, which are generally used in concrete, and having excellent uniaxial compressive strength, and settlement phenomenon. Can be prevented and the solidification time can be significantly shortened to obtain an effect of forming stable ground in a short time.
본 발명에 따른 흙콘크리트는 흙과 상술한 흙콘크리트용 시멘트 조성물을 혼합한 것으로 이는 포장대상 흙의 물성에 따라 조절할 수 있다. 일례로, 연약지반의 함수율이 많거나 높은 일축압축강도를 목표로 하는 경우 흙 100중량부에 대하여 본 발명에 따른 흙콘크리트용 시멘트 조성물을 다량 첨가할 수 있다. Soil concrete according to the present invention is a mixture of the soil and the above-mentioned cement composition for soil concrete, which can be adjusted according to the physical properties of the soil to be packaged. For example, when a large moisture content of the soft ground or high uniaxial compressive strength is aimed at, the cement composition for soil concrete according to the present invention may be added in a large amount to 100 parts by weight of soil.
바람직하게는 상기 흙콘크리트용 시멘트 조성물의 함량은 흙 100중량부를 기준으로 하여 1 내지 25중량부인 것이다. 상기 흙콘크리트용 시멘트 조성물의 함량이 1중량부 미만이면 흙콘크리용 시멘트 조성물의 효과가 미미하여 큰 강도 발현하기가 힘들고, 25중량부를 초과하면 단가가 상승하여 경제성 면에서 불리한 문제가 있다. Preferably the content of the cement composition for the soil concrete is 1 to 25 parts by weight based on 100 parts by weight of soil. When the content of the cement composition for soil concrete is less than 1 part by weight When the cement composition for soil concrete is insignificant, it is difficult to express great strength, and when it exceeds 25 parts by weight As the unit price rises, there is a disadvantage in terms of economic efficiency.
또한, 본 발명에서 골재를 대신하여 사용하는 흙은 자연상태의 현장토양을 직접 사용하는 것이 경제적인 측면에서 바람직하다. 일례로서 상기 흙은 황토, 마사토, 사질토, 해성점토 등을 들 수 있으며, 이에 한정되는 것은 아니다. In addition, the soil used in place of the aggregate in the present invention is preferable in terms of economics to use the natural site soil directly.

한편, 본 발명의 다른 일 구현예는 흙콘크리트의 중량백분율을 기준으로 하여 40 내지 45%의 함수율이 되도록 물을 가수하여 혼합 반죽하는 단계를 포함하는 흙콘크리트의 포장방법을 제공한다. On the other hand, another embodiment of the present invention provides a method for packing soil concrete comprising the step of mixing and kneading water to a water content of 40 to 45% based on the weight percentage of the soil concrete.
상기 함수율이 40% 미만이면 흙콘크리트 흐름이 적어 포장시공이 어려운 문제가 있고, 45%를 초과하면 강도 저하 및 크랙발생의 문제점이 있다. If the moisture content is less than 40%, there is a problem that the pavement construction is difficult due to the small amount of soil concrete flow, if the water content exceeds 45% there is a problem of strength degradation and cracking.
이때, 상기 혼합 반죽하는 공정은 교반공정을 통하여 실시할 수 있는데, 이에 한정되는 것은 아니며 상기 흙콘크리트와 흙을 균일하게 혼합시킬 수 있는 방법이면 어느 것이든 가능하다. In this case, the mixing kneading process may be carried out through a stirring process, but is not limited thereto, and any method may be used as long as it can uniformly mix the soil concrete and the soil.
상기 혼합 반죽된 흙콘크리트는 콘크리트의 타설방법에 따라 시공할 수 있는데, 일반적으로 시공은 도로포장에 적용하는 방법으로 실시하는 것이 좋다. The mixed kneaded earth concrete can be constructed according to the method of pouring concrete, in general, the construction is preferably carried out by the method applied to the pavement.

In general, there is a problem that the properties of the soil concrete can be paved in a very poor state depending on the physical properties such as the moisture content of the soil to be packaged during the construction of the soil packaging.
본 발명에 따른 포장방법은 포장대상 흙의 물성을 정확히 파악하여 흙에대한 흙콘크리트용 시멘트 조성물의 배합비율을 조정하는 맞춤형 포장방법으로서 장기년한에 따른 내구성을 향상시키는 효과를 얻을 수 있으며, 골재를 대신하여 도로포장 하부의 흙을 재사용(재활용)하는 환경친화적 흙콘크리트의 시공방법이다. The packaging method according to the present invention is a customized packaging method that adjusts the mixing ratio of the cement composition for soil concrete to the soil by accurately grasping the physical properties of the soil to be packaged, it is possible to obtain the effect of improving the durability according to long-term, aggregate It is a construction method of environmentally friendly soil concrete that reuses (recycles) the soil under the pavement.
또한, 본 발명의 흙콘크리트를 사용하여 포장하는 방법은 신속한 경화 처리가 가능하고 우수한 일축압축강도를 가지며, 기존의 동결융해로 인한 내구년한을 획기적으로 증가시킨 안정한 포장공법인 것이다. In addition, the method of packaging using the soil concrete of the present invention is a stable packaging method capable of rapid curing treatment, has excellent uniaxial compressive strength, and significantly increased the endurance life due to the existing freeze-thawing.
즉, 친환경 흙콘크리트를 이용한 도로포장 골재 대체를 위한 흙고화공법 및 함수비등 물성이 다양한 포장대상 흙의 포장공법으로서, 이를 보다 구체적으로 설명하면 마사토, 사질토 실트, 유기질 토양과 같은 다양한 흙콘크리트의 시공이 가능하므로 응용범위가 광범위하며 그 일례로 도로포장, 산책로, 주차장, 임도, 자전거도로, 연약지반, 농로, 축사지반, 집주면마당, 소도로, 흙벽돌, 블록, 저수지나 댐 상부도로 포장 등에 적용 가능하다. 또한, 본 발명에 따른 포장방법은 포장대상 흙을 사용하므로 채석채취로 환경훼손를 미연에 방지하여 친환경적이다. In other words, it is a soil solidification method for replacing road pavement aggregates using eco-friendly soil concrete, and a pavement method for pavement with various physical properties such as water content. More specifically, the construction of various soil concrete such as masato, sandy silt silt, and organic soil It can be used for a wide range of applications, such as road paving, trails, parking lots, forest roads, bicycle paths, soft grounds, farm roads, barn grounds, homeowner's yards, small roads, mud bricks, blocks, pavements for reservoirs or dams.

In addition, the method of paving soil concrete is fast and stable initial setting speed is semi-permanent long-term durability and excellent freeze-thawing resistance, it is possible to variously control the design compressive strength.
또한, 일반적인 콘크리트의 시공은 4℃ 이상에서 가능하기 때문에 계절에 따른 제약을 받았으나, 본 발명에 따른 흙콘크리트를 사용하면 계절에 크게 제한받지 않아 시공하기가 용이하다. In addition, the construction of the general concrete has been restricted according to the season because it is possible at 4 ℃ or more, using the soil concrete according to the present invention is not easily limited in the season it is easy to install.
도 1 내지 도 2는 본 발명에 따른 흙콘크리트를 사용하여 포장방법을 실시한 일 예를 용도별로 모식적으로 나타낸 것으로서, 도로포장에서 보조기층과 흙콘크리트의 시공단면도를 나타낸 것이다. 도 1은 산책로 및 자전거 도로, 도 2는 주차장 및 공원로에 해당하는 시공단면도이다. 또한, 도 3은 종래 도로포장의 단면을 모식적으로 나타낸 시공단면도이다. 1 to 2 schematically show an example in which the pavement method using the soil concrete according to the present invention according to the use, showing the construction cross-sectional view of the auxiliary base layer and the soil concrete in the road paving. 1 is a construction cross-sectional view corresponding to a trail and a bicycle road, and FIG. 2 is a parking lot and a park road. 3 is a construction sectional view which shows the cross section of the conventional road pavement typically.
도 3에서 보는 바와 같이 일반 도로포장시 토공량이 77cm 인데 반해, 도 1 내지 도 2에서는 본 발명의 흙콘크리트공법에 의하여 토공량을 최대 27cm로 약 50cm로 감소할 수 있다. 즉, 기층의 두께를 줄일 수 있는 것이다. 이에 따라 본 원발명은 시공예산을 절감할 수 있는 효과를 가진다. As shown in FIG. 3, the earthwork amount during general road pavement is 77 cm, whereas in FIG. 1 to FIG. 2, the earthwork amount may be reduced to about 50 cm by up to 27 cm by the soil concrete method of the present invention.

이하 본 발명의 바람직한 실시예 및 비교예를 기재한다. 그러나 하기한 실시예는 본 발명의 바람직한 일 실시예일뿐 본 발명이 하기한 실시예에 한정되는 것은 아니다. Hereinafter, preferred examples and comparative examples of the present invention are described.

흙콘크리트용 시멘트 조성물(3종 조강 시멘트, 생석회, 알루미나시멘트, 불산석고, 수산화리튬, 규불화나트륨, 카바이트, 및 플루오린화칼슘)의 각 성분을 하기 표 1에 나타낸 함량으로 측정하여 혼합하여 흙콘크리트용 시멘트 조성물을 제조하였다. 이때, 하기 표 1의 함량 단위는 중량%이다.

시공 물성 측정Construction property measurement
상기 실시예 6 내지 18에서 제조된 흙콘크리트 및 비교예 8 내지 14에 따른 콘크리트에 대하여 물성측정을 실시하였다. 측정방법은 하기와 같이 실시하였다. 또한, 일축압축강도 및 투수계수 측정시 시료의 양생기간은 7일과 28일로 각각 실시하였다. Physical properties were measured for the concrete prepared according to Examples 6 to 18 and the concrete according to Comparative Examples 8 to 14. The measuring method was performed as follows. In addition, the curing periods of the samples were measured to be 7 days and 28 days, respectively.
하기 표 3은 실시예 6 내지 18 및 비교예 8 내지 14의 결과를 나타낸 것이다. Table 3 below shows the results of Examples 6 to 18 and Comparative Examples 8 to 14.
(1) 일축압축강도(㎏/㎠)는 KS F 2405 시험방법을 적용하여 측정하였다.(1) The uniaxial compressive strength (㎏ / ㎠) was measured by applying the KS F 2405 test method.

상기 표 3에서 보는 바와 같이 마사토 및 흙콘크리트용 시멘트 조성물의 함량을 동일한 조건으로 실시한 실시예 11과 비교예 8 내지 14의 결과를 비교하면, 실시예 11은 비교예 8 내지 14에 비하여 일축압축강도가 현저하게 높았고, 동결융해저항성도 실시예 11이 비교예 8 내지 14에 비하여 매우 우수함을 알 수 있었다. As shown in Table 3, when comparing the results of Example 11 and Comparative Examples 8 to 14, which were carried out under the same conditions, the contents of the cement composition for Masato and soil concrete, Example 11 compared to Comparative Examples 8 to 14, uniaxial compressive strength Was remarkably high, and it was also found that Example 11 was very excellent in comparison with Comparative Examples 8 to 14 in terms of freezing and thawing resistance.
또한, 실시예 11의 투수계수는 비교예 8 내지 14에 비하여 현저하게 낮음을 알 수 있는데, 본 발명에서는 투수계수를 현저하게 낮추어 비나 물이 도로 포장시 노면에 흡수되는 것을 방지하는 효과를 가지며, 이로 인하여 배수성 포장이 가능하다. 배수성 포장이란 노면에서 빗물을 신속히 포장체 밖으로 배수하는 것을 목적으로 하며 배수성 포장용 아스팔트 혼합물을 표층 또는 기층에 이용, 보조기층 이하로 빗물이 침투하지 않는 구조로 하는 것이다. 또한, 본 발명에서의 투수계수가 낮음에 따라 동결융해에 강한 효과를 가지는데, 이는 물이 흙콘크리트 사이에 흡수되지 않기 때문에 겨울철 물이 얼거나 녹아 박리박락을 일으키지 않기 때문이며, 이로인해 압축강도감소률도 낮아지는 효과를 얻는 것이다. 또한, 본 발명은 동결융해에 강하기 때문에 압축강도감소률이 낮아져 내구성이 장기 유지될 수 있는 것이다. In addition, it can be seen that the permeability coefficient of Example 11 is significantly lower than Comparative Examples 8 to 14, in the present invention has a significantly lower permeability coefficient to prevent rain or water from being absorbed on the road surface when paving the road, This allows drainage packaging. Drainage pavement is intended to drain rainwater out of the pavement quickly on the road surface, and the drainage pavement asphalt mixture is used on the surface or base layer so that rainwater does not penetrate below the auxiliary base layer. In addition, the low permeability coefficient of the present invention has a strong effect on freeze-thawing, because the water is not absorbed between the soil concrete, winter water does not freeze or melt and cause peeling peeling, thereby reducing the compressive strength The rate is also lowered. In addition, since the present invention is resistant to freezing and thawing, the compressive strength reduction rate is lowered and durability can be maintained for a long time.
또한, 실시예 11과 비교예 8 내지 14의 초결 결과를 비교해 보면, 본 발명의 실시예 11가 응결속도가 보다 빠름을 알 수 있다. 즉, 종래기술에서는 초기경화가 늦어 외부습기나 환경영향 예를 들어 우수기나 안개 등에 의해 흙의 흡수률이 변화하고 이에 따라 팽윤현상이 일어나므로 추후 포장시공이 종결이 된 후에도 표면강도가 저하되고 동결융해가 발생하게 된다. 그러나 본 발명은 초기경화가 빠르기 때문에 빠른 속도로 투수계수가 낮아져 종래기술의 문제점인 팽윤현상으로 표면강도가 저하되고 동결융해가 발생하는 문제점을 방지할 수 있다. In addition, when comparing the results of the formation of Example 11 and Comparative Examples 8 to 14, it can be seen that Example 11 of the present invention has a faster setting rate. That is, in the prior art, the initial curing is delayed, so that the absorption rate of the soil is changed by external humidity or environmental influences such as rain or fog, and swelling occurs accordingly, so that the surface strength decreases and freeze-thaws even after the completion of the pavement. Will occur. However, the present invention can prevent the problem of lowering the surface strength and freezing-thawing due to the swelling phenomenon, which is a problem of the prior art, because the permeability coefficient is rapidly lowered due to the rapid initial curing.
