Early-strength soil curing agent and application thereof
The invention discloses an early-strength soil curing agent and a preparation method thereof. The early-strength soil curing agent comprises the following components in percentage by mass: 40%-60% of steel slag, 10%-30% of cement, 5%-25% of filler, 5%-20% of alkaline waste residue, 0%-13% of phosphogypsum and 0%-1% of water reducing agent. The industrial wastes such as the steel slag and the phosphogypsum are used as raw materials to replace a cement curing agent to be applied to foundation reinforcement, so that the unconfined compressive strength of the reinforced soil is improved, the problem of low utilization rate of the industrial wastes is solved, the environmental protection is facilitated, and the economic benefit is obvious.
本发明公开了一种早强型土体固化剂及其制备方法。所述早强型土体固化剂中各组分的质量百分含量为：钢铁渣40%~60%，水泥10%~30%，填充剂5%~25%，碱性废渣5%~20%，磷石膏0%~13%，减水剂0%~1%。本发明以钢铁渣、磷石膏等工业废弃物为原料，代替水泥固化剂应用于地基加固，不仅提高了加固土的无侧限抗压强度，同时解决了工业废弃物利用率低的问题，有利于环境保护，经济效益明显。
