Abstract

In order to study the cracking resistance of cement soil, the mixing and molding methods of the mixture samples were compared. In this paper, vibration stirring and traditional stirring were adopted, and static pressure molding and roller molding were adopted. The dry shrinkage test and temperature shrinkage test of cement soil samples with different mixing methods and molding methods were carried out to study the influencing factors of cracking resistance. The comprehensive test results show that the dry shrinkage coefficient and temperature shrinkage coefficient of cement soil by vibration stirring are smaller than those by traditional stirring, indicating that the cement in cement soil by vibration stirring can be more evenly distributed in the soil particles, and the cement bonding effect can be better played to form a whole among the soil particles. The cracking resistance can be improved. Under different molding methods, the dry shrinkage (temperature shrinkage) coefficient of the samples by roller molding is smaller than that by static pressure molding, and roller molding has a greater effect on improving the cracking resistance of cement soil. The roller molding method used in the test is close to the actual roller rolling method in engineering.
