摘要
对掺钢渣-矿渣-粉煤灰复合微粉混凝土冻融循环后抗压强度进行数学分析,试验结果表明,对于本实验中的三掺复合微粉混凝土而言,粉煤灰的较优掺量为20%,钢渣对混凝土的抗冻性能有一定的改善作用,矿渣的抗冻性差,对混凝土的强度和稳定性都有不良影响。
Through the mathematical analysis of the compressive strength of concrete mixed with steel slag,slag and fly ash composite micro powder after freeze-thaw cycle.The test results show that for the three admixture composite micro fly ash concrete in this experiment,the optimal dosage of fly ash is 20%,and steel slag can improve the frost resistance of concrete to a certain extent.The frost resistance of slag is poor,which has a negative impact on the strength and stability of concrete.
