水泥胶砂强度随水灰比变化的试验研究

摘要

本文根据标准砂一定而水灰比不同的条件下,水泥3天、7天和28天抗压抗折强度变化的规律,通过回归分析法得出不同水灰比时水泥胶砂强度随时间变化的关系式,为水泥检测检验工作提供一定参考.%According to the discipline of the change of cement' s compressive and flexural strength in three days, seven days and twenty-eight days,under conditions with certain standard sand and different water-cement ratio, by the regression analysis this paper got the relational expression of cement mortar strength with the time changing when water-cement ratio is different, to provide a reference for testing and inspection work of the cement.
