Description

토양응결 경화제 조성물Soil Condensation Hardener Composition

본 발명은 알카리토류 금속염, 알카리금속염에다 암모늄염을 혼합하는 것을 특징으로 하는 토양응결 경화제조성물에 관한 것이다.The present invention relates to a soil coagulant hardening composition characterized by mixing an alkali earth metal salt and an alkali metal salt with an ammonium salt.

종래에는 토양경화제를 사용하여 토양에 시멘트를 혼합하여 건축자재를 만들거나 도로포장을 하였을 경우 콘크리트 정도의 강도를 얻을 수 없었고 또한 속히 노화가 되는등 결점이 있어서 많이 이용될 수가 없었다.Conventionally, when cement is mixed with soil using soil hardener, building materials or road pavement could not be used, because the strength of concrete could not be obtained and the aging quickly occurred.

본 발명은 이와같은 결점의 원인을 분석 그 원인을 제거하여 강력하고도 노화, 풍화가 되지 않고 시간이 경과됨에 따라 점점 응결경화가 더욱 진행되는 토양경화제를 얻는 것을 목적으로 한다.The present invention aims to obtain a soil hardening agent that analyzes the causes of such defects and removes the causes thereof so that the condensation hardening is further progressed over time without being strong, aged, and weathered.

본 발명자는 좋래의 결점인 약한 강도, 노화, 풍화의 원인으로서 토양 속에 들어간 공기나 수분이 온도의 변화에 따라 팽창 또는 수축작용을 하므로서 토양을 갈라지게 하고 갈라진 틈으로 빗물이 스며들어서 토양과 시멘트간에 응결경화 작용을 하는 칼륨, 나트륨이온이 서서히 유실되어 노화, 풍화된다는 것을 발견하고 토양내에 공기 또는 물이 남아 있지 않게 하고 그 유실된 칼륨, 나트륨의 적당량을 토양에 혼합하면서 시멘트의 교착력에 의해 응결시키고 더욱 강한 강도를 얻기 위하여 암모늄염을 첨가하여 강력하고도 풍화, 노화가 방지되는 토양응결 강화제를 개발하였다.The present inventors cause the weakness, aging, and weathering, which are the defects of the swelling, so that the air or moisture in the soil expands or contracts according to the temperature change, so that the soil splits and rainwater penetrates into the cracks. It finds that potassium and sodium ions, which harden the coagulation action, are gradually lost and become aging and weathered.Then, no air or water is left in the soil, and the lost amount of potassium and sodium is mixed into the soil. In order to achieve a stronger strength, ammonium salt was added to develop a strong, weathering, and anti-aging agent.

본 발명에서는 염화나트륨(NaCl), 탄산나트륨(Na2CO3), 탄산칼륨(K2CO3), 염화마그네슘(MgCl2), 염화 암모늄(NH4Cl), 규불화마그네슘(MgSiF6), 알루민산소다 (NaAlO2) 및 염화철(FeCl3)로 구성되는 조성물의 수용액을 시멘트, 흙에 혼합하여 각종 벽돌을 생산하므로 풍화에 견디는 내노후성, 강도등이 월등하게 우수한 흙벽돌이 제조되었다.In the present invention, sodium chloride (NaCl), sodium carbonate (Na 2 CO 3 ), potassium carbonate (K 2 CO 3 ), magnesium chloride (MgCl 2 ), ammonium chloride (NH 4 Cl), magnesium silicate (MgSiF 6 ), aluminic acid Soil (NaAlO 2 ) and ferric chloride (FeCl 3 ) is mixed with an aqueous solution of cement and soil to produce a variety of bricks to produce a variety of bricks with excellent aging resistance, strength, etc. to withstand weathering.

본 발명에서 염화나트륨, 탄산나트륨, 탄산칼륨은 시멘트, 흙을 제외한 조성물의 중량을 기준으로 하여 25%, 20%, 15%가 가장 적당하다.In the present invention, sodium chloride, sodium carbonate, potassium carbonate is most suitable 25%, 20%, 15% based on the weight of the composition excluding cement, soil.

또한 염화마그네슘, 규불화마그네슘, 알루민산나트륨 및 염화철은 각각 10%, 10%, 5%, 5%가 가장 적당하다.Magnesium chloride, magnesium silicate, sodium aluminate and iron chloride are most suitable for 10%, 10%, 5% and 5%, respectively.

상기한 조성에서 염화나트륨, 탄산나트륨, 탄산칼륨은 상기한 조성비보다 적어지면 충분한 이온침출과 기공폐쇄효과를 얻을 수 없고 충분한 반응이 되지 못하며 너무 과량 첨가되면 소성건조 후 외부로 결정 석출되면서 백화현상이 발생되며, 마그네슘화합물 등은 소량첨가로 충분한 경도와 신속한 경화가 이루어지지 못하고 너무 과량 첨가하면 가사시간이 짧아져서 성형성이 좋지 않으며 경화가 너무 강하게 이루어져 각종 물리적 특성이 악화되는 단점이 있다.In the above composition, when sodium chloride, sodium carbonate and potassium carbonate are less than the above composition ratio, sufficient ion leaching and pore closing effect cannot be obtained, and sufficient reaction cannot be obtained. If too much is added, whitening phenomenon occurs as a result of crystallization to the outside after firing and drying. , Magnesium compounds, etc., due to the addition of a small amount of sufficient hardness and rapid curing is not achieved, if excessively added, the pot life is short due to poor moldability, the curing is too strong, there is a disadvantage that various physical properties deteriorate.

상기한 본 발명의 조성물은 흙, 물 및 시멘트와 함께 혼합되면 나트륨과 칼륨의 화합물이 함께 첨가되는 염화암모늄(NH4Cl)과 공존하면서 다음의 반응이 일어나는 것으로 예상된다.When the composition of the present invention described above is mixed with soil, water and cement, it is expected that the following reaction occurs while coexisting with ammonium chloride (NH 4 Cl) to which sodium and potassium compounds are added together.

NH4Cl+Na2CO3+H2O→NH4OH+NaHCO3+NaClNH 4 Cl + Na 2 CO 3 + H 2 O → NH 4 OH + NaHCO 3 + NaCl

MgSiF6+2NH4Cl+nH2O→MgCl2+SiO2+2NH4OH+nHFMgSiF 6 + 2NH 4 Cl + nH 2 O → MgCl 2 + SiO 2 + 2NH 4 OH + nHF

MgCl2+2NH4OH→2NH4Cl+Mg(OH)2 MgCl 2 + 2NH 4 OH → 2NH 4 Cl + Mg (OH) 2

이상과 같이 다량의 콜로이드상 규산과 콜로이드상 수산화마그네슘이 형성되면서 이들 콜로이드상 물질이 우수한 활성때문에 흙중에 함유되어 있는 규산알루미늄 첨가된 염화철, 시멘트중에 함유된 활성 CaO, SiO2, Al2O3, Fe2O3와 물의 존재하에 서로 결합하여 복잡한 암석과 같은 물질로 변화되는 것이다.As mentioned above, since a large amount of colloidal silicic acid and colloidal magnesium hydroxide are formed, these colloidal materials have excellent activity, such as aluminum silicate-added iron chloride contained in soil, active CaO, SiO 2 , Al 2 O 3 , Fe 2 O 3 combines with each other in the presence of water to change into a complex rock-like material.

그 결과 종래의 흙벽돌에서 존재하는 알카리 금속염은 수분침출이 쉽게 일어나 성형 후 빗물 등에 노출되면 서서히 와해되는 노화현상이 필수적이지만 본 발명에 의한 제품은 단단한 규산염구조내에 포괄되어서 노화 및 풍화가 거의 않되는 것이다.As a result, the alkali metal salts existing in the conventional soil bricks are easily leached away when exposed to rainwater after molding, so that the aging phenomenon is essential, but the products according to the present invention are hardly aged and weathered because they are enclosed in a solid silicate structure. will be.

본 발명의 경화제는 토양뿐만 아니라 연탄재등 산업폐기물 등도 응결 경화시킬 수 있어 공해방지에도 기여하는 바 크다.The curing agent of the present invention can harden condensation not only soil but also industrial waste such as briquettes, which contributes to preventing pollution.

본 경화제를 사용하여 도로포장을 할 경우 콘크리트에 결여되어 있는 탄력성이 토양에 의하여 주어지고 균열을 방지하고 풍화, 노화가 방지되고 콘크리트와 같은 강도를 나타므로 종래의 토양경화제의 단점이 모두 보완된 우수한 특성을 가지고 있다.When paving the road using this hardener, the elasticity lacking in concrete is given by soil, preventing cracks, weathering and aging, and showing the same strength as concrete. Has characteristics.

건축자재(벽돌, 보도블럭, 블럭, 기와)를 생산할 경우 압축강도가 좋은 우수한 건축자재를 저렴한 가격으로 생산할 수 있다.In the case of producing building materials (brick, sidewalk blocks, blocks, tiles), excellent building materials with good compressive strength can be produced at low prices.
