摘要
结合高速铁路连续梁工程混凝土弹性模量的试验研究,重点探讨了砂率、水胶比、粗骨料、矿物掺合料、养护时间等因素对弹性模量的影响。
Combining the experimental research about the elastic modulus of high performance concrete in continuous high- speed rail bridge project, it studies the effect of sand ratio, water-cement ratio, coarse aggregate, mineral admixture and maintenance time on elastic modulus.
