摘要
笔者在农村公路检测中发现,多数混凝土路面抗折强度达不到4.0MPa设计标准。本文从原材料、掺合料、外加剂及配合比设计等方面,综合分析探讨了道路混凝土抗折强度的影响因素,并在原材料的选用和配合比设计上,为配制道路混凝土提供了参考。
Based on the author＇s work experience in road inspection, the flexure strength of most concrete pavements cannot meet the design standard 4.0MPa. This paper in view of raw materials, mixtures, additives and proportioning design, analysed the factors to affect flexure strength of concrete pavement and give opinions on selection and proportioning design of raw materials as for reference.
