Abstract
Description
본 발명은 도로포장용 무수축 흙포장 조성물에 관한 것이다.The present invention relates to a non-shrink soil packaging composition for road paving.
특히, 토사에 고화제(CSA 소성화합물) 및 수용성 토양안정제를 포함하여 토사 색상을 그대로 유지할 수 있으면서도 강도가 매우 높으며, 토양안정제의 탄성 및 연성작용에 의해 줄눈작업이 필요없으므로 시공비용을 절감할 수 있는 도로포장용 무수축 흙포장 조성물에 관한 것이다.
In particular, the earth and sand can be kept intact by including a solidifying agent (CSA calcining compound) and a water-soluble soil stabilizer, and the strength is very high. Since the joint work is not required by the elasticity and ductility of the soil stabilizer, the construction cost can be reduced. The present invention relates to a non-shrinkable soil pavement composition for road paving.
흙을 이용한 포장 방법은 여러 가지 방법이 연구되어왔으나 현재는 약 4가지 방법이 개시되어 있다.Soil paving method has been studied a number of methods, but now about four methods have been disclosed.
첫째로, 일반 마사토를 롤러 등으로 전압만해서 하는 마사토 포장법이 있다. 이러한 포장법은 시멘트를 마사토에 무게비 약 15%정도를 넣어서 물과 되게 혼합하여 전압 다짐한다.Firstly, there is a Masato packaging method in which ordinary Masato is made only by a voltage such as a roller. In this method of packing, cement is mixed with water by putting about 15% by weight of masato in a weight ratio.
둘째로, 소일 콘크리트로 불리우며 하자율이 높고 동결융해에 약하고 가격이 저렴하며 시공이 간편하고 일반 콘크리트에 흙을 조금 약 10% 정도 넣어서 만드는 시공법과, 마사토에 시멘트로 만든 고화재를 섞어서 손으로 살짝 뭉쳐질 만큼만 물을 넣어서 전압다짐하여 시공하는 시공법이 있다.Secondly, it is called Soil Concrete, has high defect rate, is weak against freeze-thawing, inexpensive, easy to install, and puts a little about 10% of soil into general concrete, and mixes solid materials made of cement with Masato and mixes them together by hand. There is a construction method that puts water as much as quality and compacts and installs.
또한, 황산 마그네슘 혹은 염화 마그네슘 용액을 도포하고 롤러 전압 다짐하는 방법으로, 일반 흙길보다 먼지가 덜하고 유실량이 줄어드나 비가 오면 질퍽거리거리며 차도용으로 사용 불가함. 주로 운동장이나 산책로 등에 쓰이는 약액 다짐 포장이 있다.In addition, by applying magnesium sulfate or magnesium chloride solution and compacting the roller voltage, it is less dusty than ordinary dirt roads, and the amount of loss is reduced. There is a chemical compaction package mainly used for sports grounds and walks.
이외 고분자 폴리머를 물에 희석하여 도포하고 전압 다짐하는 방법이 있는데, 이러한 방법은 수성 폴리머의 결합성을 이용하여 포장하고 비가와도 질퍽거리지 않으나 투수량이 작은 문제가 있다.In addition, there is a method of diluting and applying a polymer polymer in water and compacting the voltage. Such a method has a problem in that the packing is made using the binding property of the aqueous polymer and does not squeeze even when it is rained, but the water permeability is small.
이러한 방법과 더불어 다양한 방법과 조성이 제안되고 있다.In addition to these methods, various methods and compositions have been proposed.
예를 들어, 대한민국 특허공개 제2001-11910호에서는 흙 1m3 당 ESC 경화제를 사용하여 함수율이 적고 유기질이 낮은 흙을 대상으로 사용하여 측면과 포장면의 강도가 향상되는 기술을 언급하고 있다.For example, Korean Patent Publication No. 2001-11910 mentions a technique of improving the strength of side and pavement surfaces by using ESC hardener per 1 m 3 of soil, and using soil with low moisture content and low organic matter.
대한민국 특허출원 제2005-130224호는 시멘트, 슬래그, 석고, CSA, 플라이애쉬 및 황토 파우더를 사용하여 흙의 표면질감을 그대로 표현하는 방법을 제안하고 있다.Korean Patent Application No. 2005-130224 proposes a method of expressing the surface texture of soil as it is using cement, slag, gypsum, CSA, fly ash and ocher powder.
대한민국 특허공개 제2005-105153호는 클링커 분말, 시멘트, 고로 슬래그 미분말, 무수석고, 강도 촉진제, 응결 지연제를 포함하여 원적외선 방출 및 보수, 통기성 등의 흙의 특성을 보유하고 속경성을 가지는 조성을 제안하고 있다.Korean Patent Laid-Open No. 2005-105153 proposes a composition which possesses properties of soil such as far-infrared emission and repair, breathability, including clinker powder, cement, blast furnace slag fine powder, anhydrous gypsum, strength accelerator and coagulation retardant Doing.
이들 포장재료와 공법은 흙에 석회나 시멘트 등과 같은 결합재와 화학재료인 첨가제를 이용하므로 포장후 육가크롬(Cr6 +) 등이 발생하여 친위생적이지 못하고 고가인 시멘트 함량이 증가하므로 비경제적인 문제점이 있다.These packaging materials and methods use binders such as lime and cement in the soil and additives that are chemical materials. Therefore, hexavalent chromium (Cr 6 + ) is generated after packaging, resulting in unsanitary and expensive cement content. have.
흙을 이용한 포장 시공방법은 우리나라의 경우, 봄과 겨울이 있으므로 동결융해가 발생하여 균열이 발생하여 시간경과에 대해 포장제로서 기능을 상실하는 문제점이 있다. 또, 우리나라에서는 사계절이 있어 건습이 반복되므로 포장표면이 손실되어 포장의 성능을 저하시키는 문제점이 있다.In the case of pavement construction method using soil in Korea, there is a problem of losing function as a packaging agent over time because freeze-thawing occurs and cracks occur because of spring and winter. In addition, there are four seasons in Korea, so the wet and dry is repeated, there is a problem that the surface of the packaging is lost, thereby reducing the performance of the packaging.
또한, 흙 포장은 보조기층이나 기층상부에 설치하므로 온도변화와 건습반복에 의해 균열이 발생하고 이균열을 제어하기 위해 줄눈을 설치한다.In addition, since the soil pavement is installed on the auxiliary base or base layer, cracks are generated due to temperature change and wet and dry repetition, and joints are installed to control cracks.

그러나, 상기 줄눈(10)은 차량의 주행성을 저하시킬 뿐만 아니라 설치된 줄눈부가 쉽게 파손되어 포장의 기능이 손상되는 문제점이 있다.
However, the joint 10 has a problem that not only the running performance of the vehicle is lowered, but also the joint part installed is easily damaged, thereby impairing the function of the pavement.

또한, 본 발명에서 '조성물'은 원래 혼합물과 화합물의 의미를 포함하는 용어로써, 본 발명에 있어서 '바인더 조성물'의 '조성물'은 특별한 언급이 없거나 발명의 전체적인 내용에 반하지 않는 한, '혼합물'의 의미로 사용된다.
In addition, in the present invention, 'composition' is a term that includes the meaning of the original mixture and the compound, in the present invention 'composition' of the 'binder composition' is a 'mixture', unless otherwise stated or contrary to the overall content of the invention It is used to mean '.
본 발명은 도로포장용 무수축 흙포장 조성물에 관한 것이다. 여기서, 무수축은 수축이 없는 것을 의미하나, 수축이 작은 저수축의 의미도 내포하고 있음을 전제한다.The present invention relates to a non-shrink soil packaging composition for road paving. Here, the non-shrinkage means that there is no shrinkage, but presupposes that the low shrinkage also has a small shrinkage.
본 발명에 따른 도로포장용 무수축 흙포장 조성물(이하 "흙포장 조성물"이라 함)은 토사 및 결합제 조성물을 포함한다.
The non-shrinkable soil pavement composition (hereinafter referred to as "soil pavement composition") for road paving according to the present invention includes the soil and binder composition.
상기 흙포장 조성물의 조성비는, 토사 82~90 중량% 및 결합제 조성물 10~18중량%로 되는 것이 바람직하다.
It is preferable that the composition ratio of the said soil packaging composition becomes 82-90 weight% of earth and sand and 10-18 weight% of a binder composition.
상기 흙포장 조성물 중, 토사는 자연에서 채취한 토사를 말한다. 상기 토사 중, 접착성이 있는 흙의 경우 접착력을 영구히 보존케 하고 접착력이 없는 사질토에 있어서는 접착력을 갖게 하는 역할을 한다. 이 때문에 물이나 동결작용에 대한 안정성이 확보된다.
In the soil packaging composition, earth and sand refers to earth and sand collected from nature. Among the soil, the adhesive soil serves to preserve the adhesion permanently and to have the adhesion in the sandy soil without adhesion. This ensures stability against water or freezing.
상기 흙포장 조성물 중, 결합제 조성물은 고화제 및 토양안정제를 포함한다.In the soil packaging composition, the binder composition includes a hardener and a soil stabilizer.
상기 결합제 조성물의 조성비는, 고화제 94~98 중량% 및 토양안정제 2~6 중량%로 되는 것이 바람직하다. The composition ratio of the binder composition is preferably 94 to 98% by weight of the solidifying agent and 2 to 6% by weight of the soil stabilizer.
상기 결합제 조성물 중 하나인 고화제는 흙포장 조성물의 결합강도 및 기계적 강도를 증진시키는 역할을 하게 되므로 강도와 직접적으로 연관된다. 따라서 결합제 조성물의 대부분(94~98 중량%)을 차지하게 된다. 결합제 조성물의 94 중량% 미만인 경우에는 결합강도 및 기계적 강도의 저하를 가져오고, 98 중량%를 초과하게 되면 강도가 필요 이상 증가하고 불필요한 비용이 추가되는 문제를 초래한다. One of the binder compositions, the hardener, is directly related to the strength because it serves to enhance the bonding strength and mechanical strength of the soil packaging composition. Therefore, it occupies most of the binder composition (94 to 98% by weight). Less than 94% by weight of the binder composition results in a drop in bond strength and mechanical strength, and in excess of 98% by weight results in a problem in that the strength is increased more than necessary and unnecessary costs are added.
상기한 고화제는, 클링커 분말, 알루미나계 시멘트 구조화합물, 고로슬래그 미분말, 벤토나이트, 플라이애쉬, 제올라이트 및 무수석고를 포함한다.The above-mentioned solidifying agent includes clinker powder, alumina cement structural compound, blast furnace slag fine powder, bentonite, fly ash, zeolite and anhydrous gypsum.
상기 고화제의 조성비는, 클링커 분말 15~35중량%, 알루미나계 시멘트 구조화합물 10~30중량%, 고로 슬래그 미분말 5~35중량%, 벤토나이트 5~15중량%, 플라이애쉬 10~20중량%, 제올라이트 5~25중량% 및 무수석고 15~35중량%를 포함한다.The composition ratio of the solidifying agent is 15 to 35% by weight of clinker powder, 10 to 30% by weight of alumina cement structural compound, 5 to 35% by weight of blast furnace slag powder, 5 to 15% by weight of bentonite, 10 to 20% by weight of fly ash, Zeolite 5-25 wt% and anhydrous gypsum 15-35 wt%.
상기 고화제 조성물 중, 클링커 분말은, 성분의 일부가 융해하여 전체가 괴상소결물로 형성된 덩어리를 말하는 것으로 소괴(燒塊)라고도 한다. 일반적으로는 원료로서 석회질 원료와 점토질 원료를 적당한 비율로 혼합하여 미분쇄한 후, 그 일부가 용융될 때까지 로터리 킬른(rotary kiln) 등에 의하여 소성하여 알밤 정도의 크기의 작은 덩어리로 형성된 것을 말하는 것으로서, 본 발명에서는 압축강도 및 기계적 강도에 영향을 주며, 15 중량% 미만으로 첨가되면 압축강도 및 기계적 강도가 미약하며, 35 중량% 초과하면 경화속도가 빨라 정상적인 작업시간을 확보할 수 없다In the said solidifying agent composition, clinker powder refers to the lump which a part of component melt | dissolved and the whole formed from the block sintered compact, and is also called a lump. In general, the raw material is a fine mixture of calcite raw material and clay raw material in an appropriate ratio, and then pulverized by rotary kiln or the like until a part of the raw material is melted. In the present invention, the compressive strength and mechanical strength are affected, and if the content is less than 15% by weight, the compressive strength and mechanical strength are insignificant.
상기 고화제 성분 중, 알루미나계 시멘트 구조화합물(C12A7:12CaO7Al2O3)은, 결합력과 강도증진, 경화속도에 영향을 주며, 10 중량% 미만으로 첨가되면 충분한 결합력과 강도 증진이 원활히 이루어지지 않으며 경화속도가 길어진다. 또한, 30 중량%를 초과하면 결합력과 강도는 증진되나, 경화속도가 빨라 정상적인 작업시간을 확보할 수 없다.Among the solidifying agent components, the alumina cement structure compound (C12A7: 12CaO 7 Al 2 O 3 ), affects the bonding strength and strength, the curing rate, and when added to less than 10% by weight, sufficient bonding strength and strength is smoothly achieved. Hardening speed is long. In addition, if the content exceeds 30% by weight, the bonding strength and strength are enhanced, but the curing speed is not fast enough to secure a normal working time.
상기 고화제 성분 중, 고로 슬래그 미분말은 용광로에서 선철과 함께 생산되는 것으로 비중은 2.88 ~ 2.95 범위이며 블래인 비표면적으로 6,000±500㎠/g이 바람직하며 고로 슬래그 미분말의 CaO 성분은 40 ~ 45 중량% 전후로서 알칼리도가 낮기 때문에 pH 저감에 효과적인 작용을 하는 것으로 이를 위해 5 ~ 35 중량%가 적당하다.Among the components of the solidifying agent, the blast furnace slag powder is produced together with pig iron in the smelting furnace, its specific gravity is in the range of 2.88 ~ 2.95 and the specific surface area of 6,000 ± 500㎠ / g, the CaO component of the blast furnace slag powder is 40 ~ 45 weight Since the alkalinity is low around about%, it is effective in reducing the pH. For this purpose, 5 to 35% by weight is appropriate.
상기 고화제 성분 중, 벤토나이트는 재료 분리 방지, 윤활성, 응집성 부여로 작업성을 개선하기 위한 것으로서, 5 중량% 미만으로 첨가되면 포장재의 결합력이 떨어지며, 15 중량%를 초과하면 과도한 응집현상이 발생한다.Bentonite in the solidifying agent component is intended to improve workability by preventing material separation, providing lubricity and cohesiveness, and when added in an amount less than 5% by weight, the cohesion of the packaging material is lowered. .
상기 고화제 성분 중, 플라이애쉬는 강도 증진에 영향을 주며, 10 중량% 미만으로 첨가되면 충분한 반응이 일어나지 않아 효과적인 강도를 얻을 수 없으며, 20 중량%를 초과하면 강도가 급격히 저하되는 문제점이 발생 된다.Among the solidifying agent, fly ash affects the strength enhancement, and when added to less than 10% by weight, sufficient reaction does not occur, so that the effective strength cannot be obtained, and when the content exceeds 20% by weight, the strength is rapidly decreased. .
상기 고화제 성분 중, 제올라이트는 실리콘(Si)과 알루미늄(Al)으로 이뤄진 다공성 결정으로 강한 산성을 띠어 다양한 석유화학 반응의 촉매로 활용되는 것으로서, 수산화칼슘과 포졸란 반응하여 강도 증진에 기여하게 된다. 이는 5 중량%미만으로 첨가되면 충분한 강도발현이 미약하고, 35 중량%를 초과하면 필요 이상으로 강도가 강화되므로 위의 범위 내에서 첨가되는 것이 효율적이다.Zeolite is a porous crystal made of silicon (Si) and aluminum (Al), and is used as a catalyst for various petrochemical reactions, and contributes to strength enhancement by reacting with calcium hydroxide and pozzolane. If it is added less than 5% by weight is sufficient strength expression is weak, if it exceeds 35% by weight it is effective to be added within the above range because the strength is strengthened more than necessary.
상기 고화제 성분 중, 무수석고는 슬래그의 자극제 및 강도 증진, 경화속도에 영향을 준다. 이러한 무수석고는 15 중량% 미만으로 첨가하면 슬래그의 자극 효과가 떨어져 강도에 영향을 줄 수 있고, 원활한 형성이 이루어지지 않으며, 경화속도도 늦어 안정성에도 영향을 주게 된다. 반면 35중량%를 초과하면 강도 증진효과는 얻을 수 있으나 빠른 경화속도로 정상적인 작업시간을 확보할 수 없다. 또한, 유기물질을 포함한 흙은 보통 포틀랜드 시멘트로만 처리하였을 경우 포장재의 목적으로 부적합하며, 골재의 입도는 일반적으로 최대 골재의 크기가 50mm 정도이다.
Among the hardener components, anhydrous gypsum affects the stimulant and strength enhancement of the slag and the curing rate. When the anhydrous gypsum is added in less than 15% by weight, the irritation effect of the slag may be lowered and thus the strength may be affected, and the smooth gypsum may not be formed. On the other hand, if it exceeds 35% by weight, strength enhancing effect can be obtained, but normal working time cannot be secured due to fast curing speed. In addition, soils containing organic materials are usually unsuitable for packaging purposes when treated only with Portland cement, and the aggregate size of the aggregate is generally about 50 mm in size.
상기 결합제 조성물 중 다른 하나인 (수용성)토양안정제는, 포장 후 물이 증발하면서 연속적인 필름막을 형성하기 위하여 응집하고, 동시에 흙 입자에 부착하게 되며 포장체 내부에 존재하는 공극을 안정제 입자에 의해 채워져 토사 입자와 단일체의 조직을 형성함과 동시에 접착력 및 부착력을 증진시키는 역할을 하는 것으로서, 결합제 조성물 중 2 ~ 6 중량%가 배합된다. 2 중량% 미만인 경우에는 필름막이 약하게 형성되어 토사입자가 부스러져 표면 박리가 일어날 수 있으며, 6 중량%를 초과하게 되면 고강도 고내구성을 얻을 수 있으나 많은 비용이 발생하는 문제가 있다.The (water-soluble) soil stabilizer, which is another of the binder compositions, aggregates to form a continuous film film as water evaporates after packaging, and is attached to soil particles at the same time, and voids present in the package are filled by stabilizer particles. As a function of promoting adhesion and adhesion while forming a monolithic structure with soil particles, 2 to 6% by weight of the binder composition is blended. When less than 2% by weight, the film film is weakly formed so that the soil particles may be crushed, the surface peeling may occur, if it exceeds 6% by weight can be obtained high strength and high durability, but there is a problem that a lot of cost.
상기한 토양안정제의 물성은 아래와 같다.The physical properties of the soil stabilizer is as follows.
한편, 상기 토양안정제는, 메틸메타아크릴레트, 부틸아크릴레이트, 2-에틸헥실아크릴레이트, 메타아크릴산, 라우릴황산나트륨, 리튬실리케이트, 알킬설폰산염, 과황산암모늄 및 물을 포함한다.On the other hand, the soil stabilizer, methyl methacrylate, butyl acrylate, 2-ethylhexyl acrylate, methacrylic acid, sodium lauryl sulfate, lithium silicate, alkyl sulfonate, ammonium persulfate and water.
상기 토양안정제 조성물의 조성비는, 메틸메타아크릴레트 12~16중량%, 부틸아크릴레이트 14~22중량%, 2-에틸헥실아크릴레이트 13~16중량%, 메타아크릴산 1~2중량%, 라우릴황산나트륨 0.03~0.05중량%, 리튬실리케이트 0.2~3중량%, 알킬설폰산염 0.1~2중량%, 과황산암모늄 0.03~0.2중량% 및 물 48~53중량%를 포함한다.The composition ratio of the soil stabilizer composition is 12 to 16% by weight of methyl methacrylate, 14 to 22% by weight of butyl acrylate, 13 to 16% by weight of 2-ethylhexyl acrylate, 1 to 2% by weight of methacrylic acid, sodium lauryl sulfate 0.03 to 0.05 weight%, lithium silicate 0.2 to 3 weight%, alkyl sulfonate 0.1 to 2 weight%, ammonium persulfate 0.03 to 0.2 weight% and water 48 to 53 weight%.
상기 토양안정제 성분 중, 메틸메타아크릴레트(methylmethacrylate)는 토양안정제의 안정성 및 내후성을 부여하기 위한 주성분으로서, 12중량% 미만인 경우에는 안정성 및 내후성이 저하되어 경화 시, 피막형성이 원활하지 못하고, 16중량%를 초과하게 되면 접착성이 너무 강해서 작업성이 용이하지 못하다.Of the soil stabilizer components, methyl methacrylate (methylmethacrylate) is a main component for imparting stability and weather resistance of the soil stabilizer, when less than 12% by weight, the stability and weather resistance is lowered, the film formation during the curing is not smooth, 16 When the weight percentage is exceeded, adhesiveness is so strong that workability is not easy.
상기 토양안정제 성분 중, 부틸아크릴레이트(buthylacrylate)는 토양안정제에 경화성을 부여하기 위한 주성분으로서, 14중량% 미만인 경우에는 경화가 늦는 폐단이 있고, 22중량%를 초과하면 경화가 너무 빨라서 작업시간의 확보가 어렵다.Among the soil stabilizer components, butyl acrylate (buthylacrylate) is the main component for imparting the hardenability to the soil stabilizer, when less than 14% by weight has a closed stage late hardening, when it exceeds 22% by weight hardening is too fast Difficult to secure
상기 토양안정제 성분 중, 2-에틸헥실아크릴레이트(2-ethylhexylacrylate)는 토양안정제에 경화성을 부여하기 위한 주성분으로서, 13중량% 미만의 경우에는 경화가 늦고, 16중량%를 초과하면 경화속도가 빨라서 작업시간의 확보가 어렵다.Among the soil stabilizer components, 2-ethylhexylacrylate is a main component for imparting sclerosis to the soil stabilizer. When it is less than 13% by weight, the curing is slow, and when it exceeds 16% by weight, the curing rate is fast. It is difficult to secure working time.
상기 토양안정제 성분 중, 메타아크릴산은 햇빛 등의 날씨 및 기후에 견디는 성질인 내후성(耐候性)이 우수하여 외부 환경 변화(날씨 및 기후 변화)에 의한 부식 등을 억제함과 동시에 포장체로 침투하여 일체화 시켜줌으로써 부착강도 및 인성을 개선하고, 안료 등에 의한 착색성을 좋게 하기 위하여 첨가되는 부 성분으로서, 1중량% 미만인 경우에는 위에 열거된 기능을 발휘하기에 미미하고, 2중량%를 초과하면 위에 열거된 기능이 강화되나 비용이 증가하는 문제점이 있다.Among the soil stabilizer components, methacrylic acid is excellent in weatherability, which is a property to withstand weather and weather such as sunlight, inhibits corrosion due to external environmental changes (weather and climate change), and simultaneously penetrates into the package to integrate. As a minor ingredient added to improve adhesion strength and toughness and to improve colorability by pigments, the amount is less than 1% by weight, and it is insignificant to exert the functions listed above. The function is enhanced but the cost is increased.
상기 토양안정제 성분 중, 라우릴황산나트륨(sdium lauryl sulfate)은 열린 기포로 팽창압력을 흡수하여 포장체의 수축을 억제시켜 크랙을 방지하는 역할을 한다. 0.03 중량% 미만이면 토양안정제의 점도가 높게 형성되어 끈적임이 심해 작업의 효율성이 떨어지고, 0.05 중량%을 초과하면 점도는 낮아지나 단가가 상승되어 비효율적이다.Among the soil stabilizer components, sodium lauryl sulfate serves to prevent cracks by absorbing the expansion pressure into the open bubble to suppress the shrinkage of the package. If the viscosity is less than 0.03% by weight, the soil stabilizer is highly viscous and sticky, so the efficiency of the work decreases. If the content exceeds 0.05% by weight, the viscosity is low, but the unit price is increased, which is inefficient.
상기 토양안정제 성분 중, 리튬실리케이트는 토양안정제 혼합물의 쇼킹현상을 방지하는 역할을 한다. 0.2 중량% 미만이면 쇼킹현상을 방지할 수 없고, 3 중량%를 초과하면 쇼킹현상을 방지되나 단가가 상승하게 된다.Among the soil stabilizer components, lithium silicate serves to prevent shock phenomenon of the soil stabilizer mixture. If the amount is less than 0.2% by weight, the shocking phenomenon cannot be prevented. If the content exceeds 3% by weight, the shocking phenomenon is prevented, but the unit price increases.
상기 토양안정제 성분 중, 알킬설폰산염은 토사입자의 표면장력을 저하시키고 토사입자에 침투, 분산, 기포작용을 하는 물질로서 점토질 또는 사질토의 토사입자의 혼합성을 향상시키는 역할을 한다. 0.1 중량% 미만이면 토사 혼합물의 분산성이 떨어져 고른 혼합물을 얻기 어렵고, 2 중량%를 초과하면 혼합물의 분산성은 좋아지나 단가가 상승하게 된다.Among the soil stabilizer components, the alkyl sulfonate acts to reduce the surface tension of the soil particles and to improve the admixture of the soil particles of the clay or the sandy soil as substances which penetrate, disperse, and bubble the soil particles. If it is less than 0.1% by weight, the dispersibility of the soil mixture is poor, and it is difficult to obtain an even mixture. If it exceeds 2% by weight, the dispersibility of the mixture is improved, but the unit price is increased.
상기 토양안정제 성분 중, 과황산암모늄((NH4)2S2O8)은 개시반응(initiationreaction)이 일어나며, 그 후 성장반응(propagation reaction), 종결반응(termination reaction)이 일어나 고분자인 아크릴폴리머를 생성하기 위한 촉매제 역할을 한다. 정도의 아크릴폴리머를 생성하기 위해 본 과황산암모늄은 0.03~0.2중량% 범위 내에서 배합되는 것이 바람직하다.Among the soil stabilizer components, ammonium persulfate ((NH4) 2S2O8) undergoes an initiation reaction, and then a growth reaction and a termination reaction occur to generate an acrylic polymer as a polymer. Play a role. In order to produce a degree of acrylic polymer, the present ammonium persulfate is preferably blended within the range of 0.03 to 0.2% by weight.
상기 토양안정제 성분 중, 물은 토양안정제의 원활한 혼합을 위해 필요한 성분이다. 물이 48 중량% 미만이면 혼합성이 떨어지고, 물이 53 중량%를 초과하면 혼합성은 좋으나 안정제의 끈적임이 심해 작업성이 좋지 않다.
Of the soil stabilizer components, water is a component necessary for smooth mixing of the soil stabilizer. If the water is less than 48% by weight, the mixing is poor, if the water is more than 53% by weight, the mixing is good, but the stickiness of the stabilizer is severe, poor workability.
