Groundwater-corrosion-resistant cement-soil mixing pile curing agent and preparation method thereof
The invention discloses a cement-soil mixing pile curing agent resistant to underground water corrosion and a preparation method of the cement-soil mixing pile curing agent, montmorillonite, mineral powder, fly ash, carbide slag and other industrial byproducts are adopted to replace traditional cement to serve as main curing materials, and the curing agent is prepared through different proportions. The curing material comprises 1-5 parts of montmorillonite, 10-20 parts of carbide slag and 70-85 parts of mineral powder and fly ash, and the ratio of the mineral powder to the fly ash is 7: 3-9: 1. And 8-12 parts of a sodium water glass alkali activator, wherein the modulus is 0.8-1.2. Compared with a traditional cement curing agent, the geopolymer curing agent disclosed by the invention not only can meet the mechanical property of the cement-soil mixing pile, but also has excellent underground water erosion resistance, and the applicability of the cement-soil mixing pile is enhanced. In addition, the curing agent disclosed by the invention has a remarkable environmental protection advantage, reduces carbon emission, can effectively utilize industrial by-products, provides a new thought for realizing green construction and sustainable development, and has a wide application prospect.
本发明公开了一种耐地下水腐蚀的水泥土搅拌桩固化剂及其制备方法，采用蒙脱石、矿粉、粉煤灰、电石渣等工业副产品代替传统水泥作为主要固化材料，通过不同配比制作成固化剂。固化材料包括：蒙脱石1～5份，电石渣10～20份、矿粉加粉煤灰70～85份，矿粉与粉煤灰比例7:3～9:1。钠水玻璃碱激发剂8～12份，模数为0.8～1.2。相较于传统水泥固化剂，本发明的地聚物固化剂不仅能满足水泥土搅拌桩的力学性能，而且具有优异的耐地下水侵蚀性能，增强了水泥土搅拌桩的适用性。此外，本发明的固化剂具有显著的环保优势，减少了碳排放，同时能有效利用工业副产品，为实现绿色施工和可持续发展提供了新的思路，具有广泛的应用前景。
