Description

토양과 시멘트 응결용 고상분말 조강소 조성물Solid powder crude steel composition for soil and cement condensation

본원 발명은 토양과 시멘트를 혼합하여 시멘트 가공제품(벽돌, 보도블록, 블록, 기와 등)을 제조함에 있어서, 시멘트 가공제품 제조시 토양을 주재로하여 시멘트를 혼합하여, 시멘트 가공제품을 제조할 경우, 특수조강소를 첨가하여, 제품의 경화시간을 단축하고 강도를 높이기 위하여 사용되는 토양과 시멘트 응결용 고상분말 조강소 조성물에 관한 발명이다.In the present invention, when manufacturing a cement processed product (brick, sidewalk block, block, tile, etc.) by mixing soil and cement, the cement is mixed with soil as a main material when manufacturing the cement processed product. The present invention relates to a solid powder coarse powder composition for condensation of soil and cement, which is used to shorten the curing time and increase the strength of a product by adding a special crude steel mill.

종래의 토양응결 경화제 조성물은 알카리토류금속염, 알카리금속염에다 암모늄염을 혼합한 토양응결 경화제(액상)조성물이 알려져 있으나, 경화제조성물 자체가 액상으로 되어 있어 포장비용이 많이 들고 장시간 보관한 후 사용할 경우 탄산칼슘, 수산화철, 수산화알미늄 등의 다량의 침전물이 생성되어 시멘트 가공제품 제조시 만족할만한 압축강도, 토양성분과 수경화 반응에 의한 결착 및 방수효과는 물론 풍화, 노화 방지에도, 만족할만한 효과를 얻지 못하였다.Conventional soil coagulation hardener composition is known as a soil coagulation hardener (liquid) composition of an alkali earth metal salt, an alkali metal salt and an ammonium salt. As a large amount of precipitates such as iron hydroxide and aluminum hydroxide were produced, it was not possible to achieve satisfactory compressive strength, binding and waterproofing effect due to soil component and hydrocuring reaction as well as weathering and anti-aging, when manufacturing cement processed products. .

따라서 본 발명자는 이와같은 여러가지의 결점을 시정하기 위하여 연구에 연구를 거듭한 결과 침전물을 방지하기 위하여 탄산칼슘, 규불화마그네슘, 알루민산나트륨, 염차철 대신에 염화칼륨, 염화칼슘, 염화알루미늄, 탄산마그네슘, 황산칼슘, 탄산칼슘을 본쇄하여 잘 혼합한 다음, 이 혼합된 고상분말 규산소다 3호를 첨가하여 고상분말 조강소 조성물을 발명하게 된 것이다.Therefore, the present inventors have conducted extensive research to correct these various defects, and in order to prevent the precipitate, calcium chloride, calcium chloride, aluminum chloride, magnesium carbonate, instead of calcium carbonate, magnesium silicate, sodium aluminate, ferric chloride, Calcium sulfate and calcium carbonate were chained and mixed well, and this mixed solid powder sodium silicate No. 3 was added to invent the solid powder crude steel composition.

이렇게 제조된 고상분말 조강소 조성물은 지금까지 알려진 어떤 토양응결 정화제 조성물 보다 포장비용등 제조원가면에서 저렴하고 운반 및 작업과정이 간편하며, 여러가지 토양을 골재로 사용할 수 있고 토양과 시멘트의 응결용으로 사용할 경우, 조강소를 물에 용해시킨 즉시 토양과 시멘트가 혼합된 원료에 혼합시킨 후 통상의 성형기로 벽돌, 보도블록 블록, 기와 등 시멘트 가공제품은 탁월한 압축강도, 내습성을 갖는 건축자재인 시멘트 가공제품을 얻을 수 있었다.The solid powder crude steel composition prepared in this way is cheaper in terms of manufacturing cost such as packaging cost than any soil condensing purification composition known so far, and is easy to transport and work, and can be used as aggregate for various soils and for condensation of soil and cement. In this case, the steel mill is dissolved in water immediately and mixed with raw materials mixed with soil and cement, and cement processing products such as bricks, sidewalk blocks, and tiles are processed with cement, which is a building material having excellent compressive strength and moisture resistance. Could get the product.

더욱 상세히 설명하면 다음과 같다.More detailed description is as follows.

Nacl 50g, Na2Co3200g, Mgcl2100g, NH4cl280g, Ca(OH)230g, Kc1 90g, Cacl2110g, Alcl260g, MgCo3120g, CaSo4100g, CaCo350g을 잘 분쇄하여 혼합한 다음 고상 규산소다 분말 300g을 첨가한 고상분말 조강소 조성물을 물 12-14ℓ에 용해시킨 즉시 토양 500Kg과 시멘트 40Kg를 혼합한 원료에 바로 투입하여 혼합한 후 통상의 성형기로 벽돌을 제조하있다.Nag 50g, Na 2 Co 3 200g, Mgcl 2 100g, NH 4 cl 2 80g, Ca (OH) 2 30g, Kc1 90g, Cacl 2 110g, Alcl 2 60g, MgCo 3 120g, CaSo 4 100g, CaCo 3 50g After grinding and mixing, the solid powder crude steel composition added with 300 g of solid sodium silicate powder was dissolved in 12-14 L of water, and immediately added to 500 Kg of soil and 40 Kg of cement. Ha.

제조된 벽돌에 대한 압축강도 측정치는 다음과 같다.Compressive strength measurements for the manufactured bricks are as follows.

상기 실시예에서 알 수 있듯이 토양과 시멘트 원료에 본 발명의 특수조강소 조성물을 첨가하여(압축강도가 142-198kg/㎠인) 시멘트 가공제품을 생산할 경우 지금까지 알려진 어떤 토양응결용 경화제를 사용하여 만든 토양과 시멘트 가공제품보다 동량의 시멘트 비율을 적용한 경우 압축강도, 흡수율 등이 극히 양호하고 시멘트 단독 사용할 경우와 거의 동등의 강도를 나타내고 있으며, 영하의 낮은 온도에서도 대기양생을 가능케 할 뿐만 아니라 토양의 품질에 관계없이 어느지역의 토양에서도 사용이 용이하며 효과면에서도 높은 압축강도, 동결방지, 방수성 등이 양호할 뿐만 아니라 포장 및 작업과정이 간편하고 경제적인 유용한 토양과 시멘트 응결용 고상분말 조강소 조성물을 발명하였다.As can be seen in the above embodiment when using the special crude steel composition of the present invention on the soil and cement raw material (compressive strength of 142-198kg / ㎠) to produce a cement processed product using any hardening agent for soil coagulation so far known When the same amount of cement is applied than the soil and cement processed products, the compressive strength and absorption rate are extremely good, and they are almost the same as when using cement alone. Regardless of the quality, it is easy to use in soil of any region, and in terms of effect, it has high compressive strength, freeze prevention, waterproofness, etc., and it is easy and economical for packing and working process.
