Abstract
In this paper,the differences of sulfate corrosion resistance,chloride ion penetration resistance and mechanical properties of con-crete mixed with mineral powder and fly ash under various conditions of dry-wet cycle and soaking environment were studied.The results show that the relative dynamic elastic modulus of concrete prepared under different mineral admixtures has certain differences,and the corrosion re-sistance from high to low is F40 group,F30S30 group,F40S20 group,F60 group and F0 group,among which F40 group concrete has good e-conomic benefits,and it is recommended to prepare concrete with 40%fly ash alone.Reduce the economic cost of materials on the basis of meeting the quality requirements.关键词
