摘要/Abstract

摘要： 为探究多元变量组合差异下水泥土强度的变化规律,以江西省内常见的黏性土、砂性土和砂砾土为研究对象,在不同配合比方案下开展无侧限抗压强度试验,并通过SEM测试分析水泥土微观结构。试验结果表明,在母土为最优含水状态下的三种水泥土中,水泥掺入比为21%(质量分数,下同)、水灰比为0.5、土质含砂砾率为100%的水泥土抗压强度最高,其C-S-H凝胶含量较多,孔隙数量较少,砂砾基质的粒状骨架较多。

关键词: 水泥土, 水泥掺入比, 水灰比, 土质含砂砾率, 抗压强度, 微观结构

Abstract: In order to explore the variation law of the strength of cemented soil with different combinations of multivariate variables, unconfined compressive strength tests were carried out on the common clayey soil, sandy soil and gravelly soil in Jiangxi Province under different mix schemes, and the microstructure of cemented soil was analyzed by SEM. The results show that among the three types of cemented soil with optimal water content, the cemented soil with 21% cement inclusion ratio (mass fraction, the same below), 0.5 water-cement ratio, and 100% sand and gravel content has the highest compressive strength, with more C-S-H gel content, fewer pores, and more granular skeleton in the sand and gravel matrix.

Key words: cemented soil, cement incorporation ratio, water-cement ratio, gravel content of soil, compressive strength, microstructure
