| 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。

| Abstract: | Formula studies on low-pH value cement for geological disposal were conducted with ordinary port-land 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 for 90 d pH is SiO2 content and Ca/Si ,i .e .,the content of Ca (OH)2 in products . |
