| 摘 要： | 试验研究了粗骨料的最大粒径对高强高性能混凝土的强度及弹性性能的影响,结果表明,粗骨料在高强混凝土中存在最大粒径效应,高强混凝土弹性模量随粗骨料粒径的增大而增大,并在25mm处取得最大值,各组高强混凝土应力-应变曲线的上升段更接近于直线。

| Abstract: | This article studies the maximum size of coarse aggregate＇s influence on strength and elastic ability of high-strength concrete. The result shows that coarse aggregates have the most grain size effect. The elastic modulus of high-strength concrete increases as the size of coarse aggregate increases. And the maximum size 25 mm of coarse aggregate is obtained. The upward section of stress-strain curve of each group of highstrength concrete approaches into a straight line. |
