Abstract: This article takes the shrinkage deformation of concrete as an auxiliary indicator and studies the effects of three factors, including water cement ratio, expansion agent dosage, and air entraining agent, on the impermeability performance of self compacting concrete through experiments.
The results indicate that there is a certain relationship between the shrinkage deformation of self compacting concrete and its impermeability performance; When the water cement ratio is between 0.
35 and 0.
36 and the expansion agent is between 30 and 40 kg/m3, the shrinkage deformation of self compacting concrete is small, and the impermeability performance is optimal.
Moreover, the application of air entraining agent in self compacting concrete can effectively suppress its shrinkage deformation and improve its impermeability performance.
