摘要
通过抗压强度、氯离子扩散系数和干燥收缩试验,探讨分析不同矿物掺合料对珊瑚砂混凝土性能的影响。结果发现,单掺15%矿粉和5%偏高岭土可以提高珊瑚砂混凝土的最终强度,降低氯离子扩散系数、减少珊瑚砂混凝土的干燥收缩;单掺15%粉煤灰的珊瑚砂混凝土的强度出现倒缩、渗透性能变差。
Through the compressive strength and chloride ion diffusion coefficient and the drying shrinkage test,this article analyzes different mineral admixture affect to the performance of coral sand concrete.The results show that mix 15% slag and 5% metakaolin can improve the compressive strength,reduce the chloride ion diffusion coefficient and decrease drying shrinkage of coral sand concrete,but mix 15% fly ash sample cuts down the compressive strength and make permeability badly.
