| 摘 要： | 本文研究了粗集料的最大粒径、级配和压碎指标值等对路面混凝土抗折强度的影响，结果表明，合适的最大粒径和连续级配有助于提高混凝土的抗折强度，粗集料的压碎指标值与混凝土的抗折强度没有明显的相关关系。

| Abstract: | The effect of maximum diameter,grading distribution and crushing index of coarse aggregate on flexural strength of concrete is investigated through experiments.The test results indicate that 1)using aggregate of certain maximum diameter and of continuous grading is a good way to increase the flexural strength of concrete,2)crushing index can not completely express the mechanical properties of coarse aggregate,and 3)the kind and surface state of aggregate also influence the flexural strength of concrete greatly. |
