摘要
Abstract
Based on the Yebatan Hydropower Project,a comparative analysis was conducted on the effects of three mineral admixtures—volcanic ash,phosphorus slag powder,and fly ash-on the mechanical and durability properties of concrete under different mixing ratios(20%and 30%).The study results indicate that at a 20%mixing ratio,phosphorus slag powder concrete exhibited the best compressive strength(46 MPa at 28 days)and splitting tensile strength(3.51 MPa),while fly ash concrete had the best axial tensile strength(3.36 MPa)and ultimate tensile value(1.34×10-4).In terms of durability,phosphorus slag powder concrete had the least mass loss(0.3%),and volcanic ash concrete had the highest dynamic elastic modulus(89.3%).As the mixing ratio increased to 30%,all performance indicators of the concrete showed varying degrees of de-cline,with the deterioration of fly ash concrete being the most significant.关键词
