Abstract:The effects of different lithologic manufactured fine aggregate(MFA) and contents of aggregate micro fines(AMF) on frost-resistant performance of concrete were researched,and the effects of contents of AMF on working performance,compressive strength of concrete were stu-(died.) The results show that frost-resistant performance,working performance,compressive strength of concrete may be improved by mixing proper AMF;the effects of type of mother rock on MFA concrete is not remarkable;the frost-resistant performance of MFA concrete may be improved by mixing air-entraining agent and thickening agent,or increasing the proportion of cement and AMF.
