粗集料特性对混凝土抗折强度影响研究

摘要

This paper introduced the factors influence of concrete flexural strength,mainly from the coarse aggregate maximum particle size,par-ticle size distribution,surface characteristics three aspects,researched the influences laws of coarse aggregate characteristics to concrete flexural strength,the research results provided method and basis to improve the concrete pavement performance.%介绍了影响混凝土抗折强度的因素，主要从粗集料最大粒径、颗粒级配、表面特征三个方面，研究了粗集料特性对混凝土抗折强度的影响规律，研究结果为提高混凝土路用性能提供了方法和依据。
