摘要
利用改进过的滤纸法和环境模拟法,系统研究了砂子粒径、砂浆厚度对水泥砂浆早期失水率的影响规律。研究结果表明:砂子粒径对砂浆失水率的影响因砂浆物理状态不同而有所差别;砂浆失水率随砂浆厚度的增大有所增加。
Dehydration is the main reason causing early plastic shrinkage of thin mortar. In this paper, Using im?proved filter paper and environmental simulation method to study the influence of the sand particle size and the thickness of the cement mortar on the mortar rate of early period water loss. The results show that:the impact of mor?tar sand particle size on the rate of water loss changed with the different mortar physical state;mortar dehydration rate increased with the thickness of the mortar increasing.
