中文摘要：

在煤脉石的这份报纸，可使用性，力量和耐久性，有不同的钢纤维内容层次的粗糙的总数水泥被学习了。结果显示在 28 天岁时的具体压缩力量，曲折力量和张力的切开力量增加，钢纤维内容增加，当费用和不能渗透的性质或状态与钢纤维内容增加减少时。基于新鲜具体、机械性质的可使用性和变硬的水泥的耐久性的数据，具体费用索引系统被建立由功效在煤脉石水泥评估并且优化钢纤维内容系数方法。优化结果表明系统功效系数的最大的值直到 0.87，有钢纤维 1.5% 的煤脉石水泥(V : V ) 更好表现。

英文摘要：

In this paper,workability,strength and durability of coal gangue coarse aggregate concrete with different steel fiber content levels have been studied.The results indicate that the concrete compressive strength,flexural strength and tensile splitting strength at the age of 28 days increase with the steel fiber content increasing,while cost and impermeability reduce with steel fiber content increasing.Based on the data of the workability of fresh concrete,mechanical properties and durability of hardened concrete,the concrete cost index system are established to evaluate and optimize the steel fiber content in coal gangue concrete by Efficacy Coefficient Method.The optimization result reveals that the maximum value of the system efficacy coefficient is up to0.87,the coal gangue concrete with steel fiber 1.5%（V︰V）performs better.
