Abstract
This article studies the effect of replacing slag powder with lithium slag at different dosages on the workability,compressive strength,and durability of concrete.The application of lithium slag as an admixture in concrete is analyzed through carbonation resistance,freeze-thaw resistance,and chloride ion penetration resistance tests.The results indicate that replacing slag powder with lithium slag within 40 kg/m3 has little effect on the workability and mechanical properties of concrete;but has a certain negative impact on resistance to carbonation and freeze-thaw,and a positive effect on resistance to chloride ion penetration;when the substitution amount is 60 kg/m3,it has a significant impact on all aspects of concrete;by matching ratio raw material cost analysis,mixing lithium slag powder concrete has better economy.关键词
