본 발명은 개질유화처리 정제식용유를 혼입하여 적정공기량을 확보한 균열방지용 보통콘크리트에 관한 것으로, 더욱 상세하게는 폐식용유를 정제하여 사용함으로써 환경친화적이며, 고강도 콘크리트와 달리 보통 콘크리트의 특성치인 적정공기량을 확보할 수 있고, 경화시 발생하는 건조수축 균열을 방지하여 타설된 콘크리트의 품질변화를 최소할 수 있는 개질유화처리 정제식용유를 혼입하여 적정공기량을 확보한 균열방지용 보통콘크리트에 관한 것이다.The present invention relates to an ordinary concrete for preventing cracking which is obtained by mixing refined oil for refining processing and refined edible oil, and more specifically, by refining and using waste cooking oil, it is environmentally friendly. Unlike high strength concrete, The present invention relates to a conventional concrete for preventing cracks, which can prevent drying shrinkage cracks occurring during curing and minimizes changes in the quality of the laid concrete, thereby securing an appropriate air amount by mixing refined cooking oil.

종래, 지구 온난화의 원인이 인간의 산업 활동에 의한 온실가스 농도의 증가일 가능성이 매우 높다고 지적하고 있는바, 세계 각국은 자국의 산업을 보호하되 이산화탄소 배출량을 줄이려는 노력을 하고 있다.In the past, it has been pointed out that the cause of global warming is very likely to be the increase in greenhouse gas concentration caused by human activities in the industry, and countries around the world are trying to protect their own industries but reduce their carbon dioxide emissions.

또한, 우리나라는 2011년 저탄소녹색성장기본법을 제정, 공포하고 지구를 보호하고자하는 세계정세의 흐름에 동참하고 있으며, 최근 이산화탄소(CO2) 저감 대책에 관한 연구들이 다각적으로 이루어지고 있다. In addition, Korea has participated in the global trend to establish and promulgate the Low-carbon Green Growth Basic Law in 2011 and to protect the planet. Recently, various studies have been carried out on measures to reduce carbon dioxide (CO 2 ).

특히, 건설산업분야에서는 이산화탄소 배출을 억제하는 방안의 일환으로 시멘트 사용량을 줄이고, 플라이애시나 고로슬래그 미분말 등의 산업부산물인 광물질 혼화재를 결합재로 다량 사용한 콘크리트의 사용이 증대되는 추세에 있다.Particularly, in the construction industry, the use of cement as a means of suppressing carbon dioxide emission is increasing, and the use of concrete using a large amount of mineral admixture, which is an industrial by-product such as fly ash and blast furnace slag, is increasing.

그러나 광물질 혼화재를 다량 사용한 콘크리트는 탄산화가 빠르게 진행되는 문제점이 있다고 보고되고 있다. 철근콘크리트 구조물에서 콘크리트의 탄산화는 구조물의 수명을 결정하는 가장 중요한 인자로서, 탄산화는 콘크리트 내부의 철근이 부식될 수 있는 환경으로 만듦으로써 피복콘크리트 박락, 부착력 저하에 의한 철근의 인장저항력을 감소시킴으로써 구조물의 성능을 현저히 저하시켜, 궁극적으로는 구조물의 수명을 저하시킨다.However, concrete with a large amount of mineral admixture has been reported to have a problem of rapid carbonation. The carbonation of the concrete in the reinforced concrete structure is the most important factor determining the life of the structure. The carbonation makes the reinforcing steel inside the concrete environment to be corroded, thereby reducing the tensile resistance of the reinforcing steel due to the falling of the concrete, Which ultimately deteriorates the life of the structure.

일반적으로 초고층 건축물 및 고성능 부재에 활용되는 고강도 콘크리트와는 달리 보통콘크리트는 혼화재, 첨가제를 변경함으로써 함유 공기율이 감소되는 문제를 가지고 있다.Generally, unlike high-strength concrete used for high-rise buildings and high-performance members, ordinary concrete has a problem that the air content rate is decreased by changing the admixture and additives.

대한민국 공개특허공보 제2015-0033893호에서는, 타설된 콘크리트 표면에 정제유지류(액상으로 밀도 0.7~1.3g/㎤, 함수율 0.18~0.25%, 점도 48~55cP(20℃기준))를 1회 이상 도포하여 콘크리트 공극을 미세비누입자로 충전하므로 콘크리트 탄산화가 억제되고 방지되도록, 상기 정제유지류 도포 전에 페인트가 도포되고, 도포된 상기 페인트 위로 상기 정제유지류가 도포되거나, 도포된 상기 정제유지류 위로 페인트가 도포되는 기술을 공개하고 있으나, 콘크리트 표면에만 도포함으로써 적정 공기량의 확보나 유지가 제한적이어서 경화시 발생하는 건조수축 균열이 발생할 수 있고, 타설후 경시적으로 콘크리트의 품질변화가 발생할 수 있는 문제가 있었다.Korean Patent Laid-Open Publication No. 2015-0033893 discloses a method of applying refined oils (0.7 to 1.3 g / cm3 in density, 0.18 to 0.25% in water content and 48 to 55 cP in viscosity at 20 占 폚) The concrete is filled with fine soap particles, so that the paint is applied before applying the tablet oil so that the concrete carbonation is inhibited and prevented, and the tablet oil is applied onto the applied paint or the paint is applied on the applied tablet oil oil However, there is a problem that the drying and shrinkage cracks that occur during curing may occur due to the limited amount of air and the maintenance of the proper amount of air due to application to the surface of the concrete, and the quality of the concrete may change with time after pouring.

따라서, 본 발명이 해결하고자 하는 기술적 과제는 폐식용유를 정제하여 사용함으로써 환경친화적이며, 고강도 콘크리트와 달리 보통 콘크리트의 특성치인 적정공기량을 확보할 수 있고, 경화시 발생하는 건조수축 균열을 방지하여 타설된 콘크리트의 품질변화를 최소할 수 있는 개질유화처리 정제식용유를 혼입하여 적정공기량을 확보한 균열방지용 보통콘크리트를 제공하는 것이다.Therefore, the technical problem to be solved by the present invention is to provide an environment-friendly, high-strength concrete which is environmentally friendly by refining and using waste cooking oil. Therefore, it is possible to secure a proper amount of air which is a characteristic value of ordinary concrete and to prevent drying shrinkage crack, The present invention provides a conventional concrete for preventing cracks, which is obtained by mixing refined oil for refining processing and minimizing changes in the quality of concrete.

본 발명에 따르는 개질유화처리 정제식용유를 혼입하여 적정공기량을 확보한 균열방지용 보통콘크리트는 압축강도 50MPa 이하 보통콘크리트에서 발생하는 공기량 감소를 방지하기 위하여 혼화재 배합에 유화처리 정제식용유를 포함하는 것을 특징으로 한다.The ordinary concrete for preventing cracking, in which an adequate amount of air is ensured by mixing the modified oil-refining-processed cooking oil according to the present invention Compressive strength of 50 MPa or less To prevent the decrease in the amount of air generated in ordinary concrete, it is characterized in that the admixture contains emulsification-treated refined cooking oil.

이는 종래 개질형 정제식용유(특허등록번호:KR 1281024 B)를 사용시, 균열저감에는 효과가 좋으나, 공기량 확보(3 내지 6부피%)가 불가능하므로 계면활성제, 유기계 첨가제 또는 무기계 첨가제를 포함한 개질유화처리된 정제식용유를 사용하여 균열을 방지하고, 적정 공기량을 확보하기 위한 것이다.This is because, when using conventional reforming-type refined cooking oil (Patent Registration No. KR 1281024 B), it is effective to reduce cracks, but it is not possible to secure an air amount (3 to 6 vol%). Therefore, a modified emulsification treatment including a surfactant, an organic additive, This is to prevent cracks by using the refined cooking oil and ensure an appropriate air amount.

상기 보통콘크리트는 시공표준에 따라 3 내지 6 부피%의 함유공기량 기준을 요구하고 있으나, 통상의 정제식용유를 사용하면, 이 기준을 맞추기 어려워 개질유화처리된 정제식용유를 사용한다.The above-mentioned ordinary concrete is required to have an air content standard of 3 to 6% by volume in accordance with the construction standard. However, when using ordinary refined edible oil, refined edible oil which is difficult to meet these standards is used.

상기 혼화재는 보통콘크리트 배합시 사용하는 골재로서, 모래, 자갈, 플라이애시, 고로슬래그 미분말, 실리카퓸, 굵은 골재, 잔골재, 팽창재 또는 착색재 등을 포함할 수 있으며, 종래 사용되는 골재를 다양하게 사용할 수 있음은 물론이다.The above-mentioned admixture is generally used for mixing concrete, and may include sand, gravel, fly ash, blast furnace slag, silica fume, coarse aggregate, fine aggregate, expanding material or coloring material, Of course.

이러한 정제식용유는 콩기름, 옥수수기름, 땅콩기름, 카놀라유, 유채씨유, 올리브유 또는 팜유를 사용 후 재활용을 위하여 포집하여 이물제거를 위한 공정을 거친 폐식용유인 식물성 기름인 특별하게 한정할 것은 아니며, 천연재인 관계상 콘크리트의 친환경적인 특징을 부여할 수 있으며, 여기에 개질처리제를 사용하여, 액체를 미세한 입자로 분산시켜 서로 혼합이 잘 되지 아니하는 두 종류의 액체를 혼합 분산시켜 분리되지 않도록 안정화시키는 역할을 한다.Such refined edible oil is not particularly limited, but is not limited to, vegetable oil, which is soybean oil, corn oil, peanut oil, canola oil, rapeseed oil, olive oil or palm oil, which is collected and used for recycling, It is possible to impart the environmentally friendly characteristics of concrete due to the inherent relationship, and to disperse the liquid into fine particles by using a reforming treatment agent to stabilize the two types of liquids which are not mixed with each other .

여기에 개질처리제 5 내지 20 중량%를 정제식용유 80 내지 95 중량%의 비율로 혼합한 후, 교반기로 1,000 rpm 내지 4,000 rpm에서 30분 내지 90분 동안 교반함으로써 제조하고, 교반속도가 1000 rpm 미만에서는 유동성이 떨어지고, 4,000 rpm을 초과하면 경제성이 떨어지는 문제가 있을 수 있다.Mixing 5 to 20% by weight of the modifying agent at a ratio of 80 to 95% by weight of refined cooking oil, and stirring the mixture at 1,000 to 4,000 rpm for 30 to 90 minutes with a stirrer. When the stirring speed is less than 1000 rpm There is a problem that the fluidity is deteriorated and the economical efficiency is lowered when it exceeds 4,000 rpm.

또한, 교반하는 시간은 30분 내지 90분이며, 30분 이내에서는 혼합이 균질하게 이루어지지 않으며, 90분 이상 혼합시 과혼합되므로 경제성이 떨어질 수 있다.In addition, the stirring time is from 30 minutes to 90 minutes, the mixing is not homogeneous within 30 minutes, and the mixing is mixed with the mixing for 90 minutes or more.

이러한 개질처리제로 사용되는 물질로는 본 발명의 목적을 달성할 수 있는 한, 어떠한 물질도 사용할 수 있으나, 밀도: 0.8∼1.2 g/cm3, 활성도: 20∼40%, 점도: 10∼50 cP 및 디소듐 함량 5∼50몰인 특징을 갖는다.The material used as such a modifying agent may be any material as long as the object of the present invention can be attained, but the density is preferably 0.8 to 1.2 g / cm 3 , the activity is 20 to 40%, the viscosity is 10 to 50 cP And a disodium content of 5 to 50 moles.

상기 개질처리된 정제식용유 100 중량부에 대하여 기능성 첨가제 2 내지 6 중량부를 사용할 수 있다. 2 to 6 parts by weight of a functional additive may be used for 100 parts by weight of the refined edible oil.

만일 기능성 첨가제가 2 중량부 미만이면, 적정공기량이 확보되지 못하므로, 동결융해에 의한 내구성 저하 및 타설 후에 수축 균열이 발생할 수 있으며, 반대로 6 중량부를 초과하면, 공기량 확보에는 유리하나 경화후에 압축강도가 저하될 수 있으며, 경제성이 저하될 수 있다.If the amount of the functional additive is less than 2 parts by weight, an adequate air amount can not be secured. Therefore, durability due to freezing and thawing may occur and shrinkage cracks may occur after pouring. Conversely, if the amount exceeds 6 parts by weight, And the economic efficiency may be lowered.

상기 기능성 첨가제는 계면활성제, 유기계 첨가제 또는 무기계 첨가제를 포함할 수 있는데, 계면활성제는 기름과 물이 원활하게 혼합될 수 있도록 하는 물질로, 친수성 작용기와 친유성 작용기를 함유하고 있는 물질이다.The functional additive may include a surfactant, an organic additive, or an inorganic additive. The surfactant is a material that allows smooth mixing of oil and water, and contains a hydrophilic functional group and a lipophilic functional group.

* 굳지 아니한 콘크리트의 경우 * For non-hardened concrete

비교예1에서 볼 수 있듯이, 정제식용유를 물과 함께 혼입하게 되면 슬럼프가 저하하는 경향을 내고, 비교예2에서 처럼 혼입시기를 늦추는 경우에 슬럼프가 회복하는 경향을 볼 수 있다.As can be seen from Comparative Example 1, when the refined cooking oil is mixed with water, the slump tends to decrease and the slump tends to recover when the mixing time is slowed as in Comparative Example 2.

이에 대하여, 실시예 들에서 볼 수 있듯이, 비교예 보다 슬럼프 특성이 우수하고, 특히 혼입시기가 늦어지는 경우에 약간 상승하는 특성을 나타내고 있음을 알 수 있는데, 이는 비교예와는 달리 시멘트 표면의 알칼리와 반응으로 인한 유동성 저하가 크지 아니함을 알 수 있다.On the contrary, as can be seen from the examples, it can be seen that the slump characteristics are better than those of the comparative examples, and the characteristics are slightly increased especially when the mixing time is delayed. This is because unlike the comparative example, And the decrease in fluidity due to the reaction is not large.

또한, 비교예의 경우에 공기량은 정제식용유를 물이 둘러싸는 효과를 가져서 공기량이 확보되지 아니함에 반하여 본 발명에 따르는 실시예들은 규격에서 제안하는 3 내지 6% 범위를 만족하고 있음을 알 수 있다.Also, in the case of the comparative example, the amount of air has the effect of enclosing the purified edible oil in the water, so that the air amount can not be ensured. On the contrary, the embodiments of the present invention satisfy the range of 3 to 6% proposed in the standard.

* 경화 콘크리트의 경우* For hardened concrete

비교예 1의 경우에 압축강도가 낮고 비교예2에서와 같이 혼입시기를 늦추는 경우에는 압축강도가 개선되는 효과를 가지기는 하나, 압축강도가 크게 개선되지 아니함을 알 수 있다.The compressive strength is not greatly improved although the compressive strength is improved when the compressive strength is low in Comparative Example 1 and the mixing time is slowed as in Comparative Example 2, although the compressive strength is improved.

그러나 본 발명에 따르는 실시예들은 초기 압축강도는 물론 경화에 따라 압축강도가 개선되고 있고, 더욱이 혼입시기를 늦춘 실시예 7, 8의 경우에는 압축강도가 더 개선되는 특징을 나타내고 있음을 알 수 있는데, 이는 콘크리트 조직중 모세관 공극에서 비누화 반응을 일으켜 강도저하를 방해하지 않고 오히려 정제식용유가 모세관 공극에서 팽창하게 되어 건조수축을 방지하고 있는 것으로 파악된다.However, it can be seen that the embodiments according to the present invention have improved compressive strength in accordance with hardening as well as initial compressive strength, and further improved compression strength in Examples 7 and 8 in which the mixing time is slowed , Which is caused by the saponification reaction in the capillary pores of the concrete structure, does not interfere with the strength decrease, but rather the refined edible oil is expanded in the capillary pore, thereby preventing drying shrinkage.

또한, 비교예의 경우에 건조수축 길이변화율이 혼입시기를 조절하여도 큰 개선을 보이지 아니한 반면에, 본 발명의 경우에는 크게 개선됨을 알 수 있다.Also, in the case of the comparative example, the rate of change of the shrinkage length of shrinkage does not show a significant improvement even when the mixing time is adjusted, but it can be seen that the present invention is greatly improved.
