摘要/Abstract

摘要： 为了合理利用机制砂、石屑组成的复合砂,从而缓解天然河砂的不足,通过采用级配合成计算的方法快速确定两者之间的最佳搭配比例,以获得满足国家规范II区中砂技术指标要求的复合砂。分别研究了不同掺配比例的复合砂对C30~C50强度等级混凝土工作性、力学性能及耐久性能的影响。结果表明,不同组合比例的复合砂对混凝土性能具有不同程度的改善作用,当机制砂与石屑二者的比例为6c∶4(质量比)时,各强度等级混凝土综合性能最优。

Abstract: In order to make rational use of the composite sand composed of manufactured sand and stone chips to alleviate the deficiency of natural river sand, the optimal matching ratio between them was determined quickly by using the method of grade-combination calculation, so as to obtain the composite sand that meets the technical requirements of sand in area II of the national standard. Then, the effects of composite sand with different compound ratio on the workability, mechanical properties and durability of C30 to C50 strength grade concrete were studied respectively. The results show that, different combination ratio of composite sand improve the performance of concrete to different degrees. When the ratio of manufactured sand to stone chips is 6∶4 (mass ratio), the comprehensive performance of each strength grade concrete is the best.

Key words: manufactured sand, stone chip, workability, mechanical property, durability, economy
