Abstract
In this paper,the shrinkage performance,chloride ion shrinkage resistance,impermeability and compressive strength of C30 and C50 concrete with different content of ore powder were tested.The results show that the early strength of concrete mixed with mineral powder is lower than that of ordinary concrete,but it will increase further after the curing age reaches a certain number of days.The compressive strength of concrete decreases with the increase of mineral powder content,but its durability also improves.The article suggests adjusting the amount of mineral powder according to actual needs in engineering practice,and fully improving the performance of concrete.关键词
