Abstract

Abstract: Strength is an important index to evaluate the solidification effect of cement soil and engineering design and construction inspection. The unconfined compressive strength test of cement mortar solidified soil was carried out. The results showed that the strength growth rate of cement mortar solidified soil increased linearly with the sand content, which was the maximum at 7d, and tended to be stable after 14d. The strength of solidified soil increased with age, and the initial growth rate was relatively fast. Compared with cement soil, the coefficient of deformation of cement mortar solidified soil did not slow down obviously in the later period. Taking cement mortar solidified soil as cement soil for strength calculation, the strength prediction equation of cement solidified soft soil at full age could well reflect the strength growth rule of cement mortar solidified soil.
