| Abstract: | 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. |
