Soil stabilizer for road surface layer pouring and preparation method thereof
The invention discloses a soil stabilizer for road surface layer pouring and a preparation method thereof. The self-repairing concrete comprises the following components in percentage by weight: 30-40% of cement, 10-15% of lime, 5-10% of sodium silicate, 10-15% of bentonite, 2-5% of a polymer additive, 1-3% of a fiber reinforced material, 1-3% of nano calcium carbonate, 0.5-1% of biological enzyme, 2-4% of self-repairing microcapsules and a proper amount of water. According to the soil stabilizer, the nano calcium carbonate, the biological enzyme and the self-repairing microcapsule are added, so that the compressive strength and the water stability of the material are remarkably improved. Firstly, due to the ultrahigh specific surface area and the nanoscale particle size of nano calcium carbonate, a tighter filling effect can be formed in soil, the binding force among soil particles is enhanced, and therefore the overall compressive strength is improved. In an experiment, the compressive strength of the embodiment added with the nano calcium carbonate reaches 4.0 MPa after 28 days, the strength is doubled compared with 2.0 MPa of a reference example 1, and the remarkable effect of the nano material on the aspect of enhancing the soil structure is shown.
本发明公开了一种用于道路面层浇筑的土壤固化剂及制作方法，本发明包括以下重量百分比的组分水泥30‑40％、石灰10‑15％、硅酸钠5‑10％、膨润土10‑15％、聚合物添加剂2‑5％、纤维增强材料1‑3％、纳米碳酸钙1‑3％、生物酶0.5‑1％、自修复微胶囊2‑4％及适量的水。本发明的土壤固化剂通过加入纳米碳酸钙、生物酶和自修复微胶囊，显著提升了材料的抗压强度和水稳性。首先，纳米碳酸钙由于其超高的比表面积和纳米级的粒径，能够在土壤中形成更紧密的填充效果，增强土壤颗粒之间的结合力，从而提高整体抗压强度。在实验中，加入纳米碳酸钙的实施例在28天后的抗压强度达到了4.0MPa，相较于对照例1的2.0MPa，强度提高了一倍，显示出纳米材料在增强土壤结构方面的显著效果。
