Soft soil curing agent, method for curing soft soil and application of soft soil curing agent
The invention relates to the technical field of soil solidification, in particular to a soft soil solidifying agent, a method for solidifying soft soil and application of the soft soil solidifying agent. The soft soil curing agent provided by the invention comprises cement, aluminosilicate minerals and an alkaline activator, in the soft soil curing agent, silicon-oxygen bonds and aluminum-oxygen bonds of the aluminosilicate minerals are subjected to a fracture-recombination process under the action of the alkaline activator, so that a three-dimensional cross-linked network is generated in cement-cured soft soil, and the curing effect of the cement-cured soft soil is improved. The three-dimensional cross-linked network further improves the solidification effect of the cement on the soft soil, the permeability coefficient of the solidified soft soil is 2.6 * 10 <-8 > cm/s when the solidified soft soil is maintained for 7 days, and the unconfined compressive strength of the solidified soft soil can reach 3.26 Mpa when the solidified soft soil is maintained for 28 days. According to the soft soil curing agent, the method for curing the soft soil and the application of the soft soil curing agent, the technical problems that an existing soft soil curing agent is poor in bead triangle soft soil curing effect and high in cost can be solved.
本申请涉及土壤固化技术领域，具体涉及一种软土固化剂、固化软土的方法及其应用。本申请提供的软土固化剂包括水泥、铝硅酸盐矿物以及碱性激发剂，软土固化剂中，铝硅酸盐矿物在碱性激发剂的作用下，硅氧键和铝氧键发生断裂‑重组过程，从而在水泥固化软土中生成三维交联网络，三维交联网络进一步提高了水泥对软土的固化效果，体现在固化软土7天养护期时其渗透系数为2.6×10‑8cm/s，28天养护期时其无侧限抗压强度可以达到3.26Mpa。本申请提供的一种软土固化剂、固化软土的方法及其应用，可以解决现有软土固化剂对珠三角软土固化效果不佳且成本较高的技术问题。
