摘要
分析了影响道路混凝土抗折强度的因素,研究了粗集料级配对道路混凝土抗折强度的影响,通过三种不同级配粗集料的对比试验表明合理的级配能大幅度提高道路混凝土的抗折强度。
The effect of grading distribution of coarse aggregate on flexural strength of road concrete was studied?Contrast experiments of three kinds of different coarse aggregate on grading distribution indicated that:rational grading distribution could boost greatly flexural strength of road concrete?
