摘　　要：通过混凝土力学性能的试验,研究粉煤灰和矿粉对混凝土力学性能的影响规律,确定粉煤灰和矿粉掺量的适宜比例。试验结果表明:结合本次试验得出高性能混凝土劈裂抗拉强度与抗压强度拟合公式fp l=0.1583f0c.u762,相关系数为0.89;粉煤灰掺量23%、矿粉掺量10%的混凝土为较佳配合比。According to the experiment of concrete mechanical properties,influences of fly-ash and slag on mechanical properties of concrete were investigated,the suitable dosage of fly-ash and slag were determined.The experiment test suggests that a formula fpl=0.1583f 0.762cu is presented for high performance concrete compressive and splitting strength,and the index of correlation is 0.89;the proportion of concrete replaced cement with 23% fly-ash and 10% slag is better.
