摘要
粉煤灰作为一种掺合料,掺入混凝土中对混凝土的性能有一定的影响。文中研究了粉煤灰中不同含量的游离氧化钙对混凝土坍落度、抗压强度、混凝土早期抗裂性能的影响,得出粉煤灰中的游离氧化钙对混凝土坍落度和抗压强度的影响比较显著,对混凝土的早期抗裂性能影响微乎其微。
As an admixture,fly ash has a certain influence on the performance of concrete.In this paper,the influence of different content of free calcium oxide in fly ash on concrete slump,compressive strength and early crack resistance of concrete is studied.It is concluded that the free calcium oxide in fly ash has a significant effect on concrete slump and compressive strength,but has little effect on the early crack resistance of concrete.
