超高强度高炉矿渣细骨料混凝土的试验研究

The test research on ultra high strength blast furnace slag fine aggregate concrete

通过混凝土配合比设计和力学性能试验,探讨了高炉矿渣代替天然砂作为超高强度混凝土细骨料的可行性,并对比了高炉矿渣代砂混凝土与天然砂混凝土的压缩强度,结果表明:高炉矿渣细骨料混凝土拌合物工作性能优良,压缩强度超过了100 MPa。

Through the concrete mix proportion design and mechanical properties test,this paper discussed the feasibility of blast furnace slag instead of natural sand as ultra high strength concrete fine aggregate,and compared and analyzed the compression strength of blast furnace slag for sand and natural sand concrete,the results showed that the blast furnace slag fine aggregate concrete mixture had good performance,the compression strength more than 100 MPa.
