concrete e crushing strength 混凝土抗压强度
The effect of maximum diameter, grading distribution and crushing index of coarse aggregate on flexural strength of concrete is investigated through experiments.
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。
Experimental results show that the compressive strength of concrete is closely related not only to the water-to-cement ratio, but also to the crushing value of aggregate.
试验结果表明，混凝土抗压强度不仅与水灰比密切相关，而且与骨料压碎指标有关。
