Experiment Study on Viscosity Behavior and its Temperature Influence of Cement Silicate Grouts

Abstract:

The basic characteristics of the cement-sodium silicate grout were researched. Viscosity tests were performed. The viscosity curve and temperature curve with time were obtained. The change law of viscosity was analyzed. According to the varying characteristics of grout viscosity, the process was divided into three stages: low viscosity period, the growth period and curing period. solidification tests were carried out for cement-sodium silicate grout with different temperatures, densities and water-cement ratios. Three parameters affected the initial setting time of the grout significantly.
