摘要:
为研究土质对于水泥土性质的影响,选取武汉市黏土、粉质黏土、细砂3种土样按不同的水泥掺入比设计12组室内对照试验,研究不同土质水泥土无侧限抗压强度(qu)和渗透系数(k)的差异,并运用扫描电子显微镜(SEM),观察并分析不同土质水泥土的微观固化改良情况。研究表明:水泥土宏观性质和微观固化情况均明显受到土质的影响; 细砂质水泥土qu受水泥掺入比影响最大,黏土最小,两者相差明显; 在同一水泥掺入比下,黏土质水泥土k要远小于细砂,此外黏土对于水泥水化情况影响也大于另外两种土质。
Abstract:
In order to study the effect of soil factors on the properties of cement soil,12 groups of specimens were prepared using clay,silty clay and fine sand from Wuhan with different cement mixing ratio to investigate differences of unconfined compressive strength(qu)and permeability(k)between different soils.Scanning electron microscope(SEM)was used to analyze the consolidation of cement soil.Results showed that the macro properties and solidification of cement soil were obviously affected by soil properties.The cement mixing ratio had the most influence on qu by fine sand cement soil and the least influence by clay cement soil and the difference was obvious.In the same cement mixing ratio,k of clay cement soil was much smaller than that of fine sand cement soil,and the influence of clay on the hydration of cement was greater than that of the other two clays.
