Abstract
Based on orthogonal experimental design,high ductility cement-based composite materials with different mix proportions were de-signed.The effects of fly ash replacement rate,slag powder replacement rate,and fiber volume fraction on the compressive strength,flexural strength,and tensile strength of ECC were studied,and the optimal mix proportion of ECC was determined.The results showed that the fiber volume fraction had the greatest impact on the mechanical strength of ECC.At 7 days,the effect of fly ash replacement rate on the mechanical strength of ECC was greater than that of slag powder replacement rate.At 28 days,the effect of slag powder replacement rate on the mechanical strength of ECC was greater than that of fly ash replacement rate.关键词
