不同母土对水泥土微观结构及强度的影响
Influences of Different Parent Soils on Microstructure and Strength of Cemented Soil
摘要
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.关键词
