摘要
综合评价了粉煤灰、硅粉对水泥砂浆早期收缩开裂和强度的影响,进一步研究了粉煤灰、硅粉对砂浆自由收缩、初始开裂时间以及初始开裂时抗折强度的影响,在本试验材料体系内,优化出开裂敏感性相对较优的水泥基材料组成。
The paper has the comprehensive evaluation of the influence of fly ash,silica fume and cement mortar on shrinkage and strength in early period,researches on the influence of the fly ash,silica fume on mortar＇s free shrinkage,the crack time in early period,and on the flexural strength on cracks in early period,and optimizes the cement material components with better cracking sensibility.
