Cement slurry additive for foundation treatment
The invention discloses a cement slurry additive for foundation treatment, and belongs to the field of geotechnical engineering foundation treatment. The additive is mainly prepared by uniformly mixing a quick-setting component as a main material and a mineral admixture, an early-strength component and an alkaline activated component as auxiliary materials and comprises the components in parts byweight: 0.60-0.85 part of the quick-setting component, 0.07-0.13 part of the mineral admixture, 0.03-0.12 part of the early-strength component and 0.05-0.15 part of the activated component. The additive accelerates the hydration rate of cement, increases the consistency of cement slurry, solves the problems of too large initial fluidity and too long initial setting time of the cement slurry underthe condition of a high water cement ratio, and realizes effective regulation and control of the initial fluidity and the initial setting time of the cement slurry.
本发明公开了一种地基处理用水泥浆液添加剂，属于岩土工程地基基础处理领域。该添加剂主要以速凝组分为主，辅以矿物掺合料、早强组分和碱性激发组分后均匀混合而成，其组分为：速凝组分0.60～0.85份，矿物掺合料0.07～0.13份，早强组分0.03～0.12份，激发组分0.05～0.15份。该添加剂加快了水泥的水化速率，增加了水泥浆液的稠度，解决了高水灰比条件下的水泥浆液初始流动度过大和初凝时间太长的问题，实现了对水泥浆液的初始流动度和初凝时间的有效调控。
