摘要
为了明确液态粉煤灰材料的干燥收缩特性,通过试验,系统分析了影响液态粉煤灰干缩特性的主要因素及其变化规律,试验结果表明,液态粉煤灰的干缩系数随含水量和水泥含量的增加而增大,干缩速率随着液态粉煤灰龄期的增加而减小。
In order to find out the dry shrinkage properties of fluid fly ash,the main factors influencing the dry shrinkage properties of fluid fly ash and its change laws were studied systematically through experiments. The test results indicate that the dry shrinkage coefficient of fluid flay ash would increase with the water content and cement content increased. Dry shrinkage speed would decrease with the curing age increased.
