摘要/Abstract

摘要： 采用普通硅酸盐水泥与硅灰体系进行低碱度(low-pH值)水泥配方开发,确定了前期试验中低碱度水泥的关键表征参数,并对水泥与硅灰体系进行试验验证。试验结果表明,影响低碱度水泥配方初凝、终凝时间和28 d抗压强度的主要因素是水/干料的值,影响低碱度水泥配方90 d的pH值的主要因素是SiO₂含量以及Ca/Si值,即产物中的Ca(OH)₂含量。

关键词: 地质处置, 低碱度水泥, 配方

Abstract: Formula studies on low-pH value cement for geological disposal were conducted with ordinary portland cement and silica fume employed. The key parameters thereof are also determined. Verification tests of cement and silica fume system were carried out. The results show that, for such a low-pH value cement, the major factor which effecting initial, final setting time and 28 d compressive strength is water/dry materials, while that for90 d pH is SiO₂ content and Ca/Si, i.e., the content of Ca(OH)₂ in products.

Key words: Geological disposal, Low-pH cement, Formulation
