| 粗骨料最大粒级及颗粒级配影响混凝土的抗折强度，本文主要研究了粗骨料最大粒级、粗骨料单级配、二级配、三级配对混凝土抗折强度的影响。研究表明，粗骨料的最大粒级及颗粒级配对混凝土抗折强度影响很大，合理的最大粒级和级配能够提高混凝土的抗折强度。 |
| 英文摘要: |
| The maximum particle size and particle size distribution of coarse aggregate affect the flexural strength of concrete. This paper mainly studies the influence of coarse aggregate maximum particle size, coarse aggregate single gradation, two gradation, and three gradation on the flexural strength of concrete. The research shows that the maximum particle size and particle size of coarse aggregate have great influence on the flexural strength of concrete, and the reasonable maximum particle size and gradation can improve the bending strength of concrete. |
