摘 要:研究了钢渣-矿渣-粉煤灰复合微粉混凝土的抗冻性能,分析了冻融循环前后复合微粉混凝土的抗压强度和动弹性模量变化规律。结果表明:当m钢渣∶m矿渣∶m粉煤灰=2∶1∶1时,复合微粉的最优掺量为50%;当m钢渣∶m矿渣∶m粉煤灰=1∶2∶1时,复合微粉的最优掺量为10%;当m钢渣∶m矿渣∶m粉煤灰=1∶1∶2时,复合微粉的最优掺量为40%;当m钢渣∶m矿渣∶m粉煤灰=1∶3∶1时,复合微粉的最优掺量为30%。
Abstract: The frost resistance of steel slag and slag and fly ash composite micro powder concrete was studied, and the change rule of compressive strength and dynamic elastic modulus of composite micro powder concrete before and after freeze-thaw cycle was analyzed. The results show that when msteel slag∶mslag∶mfly ash=2∶1∶1, the optimum content of composite micro powder is 50%. When msteel slag∶mslag∶mfly ash=1∶2∶1, the optimum content of composite micro powder is 10%. When msteel slag∶mslag∶mfly ash=1∶1∶2, the optimum content of composite micro powder is 40%. When msteel slag∶mslag∶mfly ash=1∶3∶1, the optimum content of composite micro powder is 30%.
