Abstract

Abstract: Temperature contraction coefficient is a parameter for material expansion and contract property when temperature becomes high ot low. Through the test in lab, the temperature contraction coefficient of lean concrete is studied and analyzed by the paper. The testing results are important parameters for calculation of temperature stress of lean concrete road base.

Key words: road base, lean concrete, temperature contraction, coefficient

摘要： 温度收缩系数是反映材料热胀冷缩特性的参数,贫砼基层材料的温缩特性又直接影响到温度应力.笔者通过室内试验,从水泥含量、集料种类、含水状态等方面研究分析了贫砼温度收缩系数随温度变化的特性,试验结果为贫砼基层结构温度应力的计算提供了重要的参数.

关键词: 道路基层, 贫砼, 温度收缩系数
