摘要
粉煤灰掺入混凝土后,不仅节约水泥,而且能提高混凝土的抗裂性。在此从极限拉伸、抗拉强度、弹性模量、水化热、温度场、自由板和嵌固板的温度应力的实验数据或计算结果对掺与不掺粉煤灰混凝土的抗裂性进行评价分析,为大体积混凝土的防裂问题提供了科学依据。
The addition of flyash to the concrete not only save the cement and also enhance the anticrack capability.From the analysis of stress,strength,temperature rise caused by concrete hydration and the temperature stress in the free slab and embeded slab, conclusion was drawn that flyash could improve the anticrack ability of concrete.
