摘要
通过对半刚性材料干燥收缩机理和现常用测试方法优缺点分析,设计了新的更能模拟工程实际的测试仪器,用该仪器进行了不同温度、湿度环境下的不同细集料级配、不同结合料配比的干燥收缩试验,揭示了半刚性基层材料的收缩特性,并提出减少干燥收缩的方法。
Through analyzing the mechanism of generating dry shrinkage of semi-rigid materials and the advantages and shortcomings of general testing ways, the new testing equipment which can simulate engineering practice is designed, and the dry shrinkage tests with mixture of different fine aggregate gradation and different proportion of inorganic materials in different temperature and moisture are carried out. The methods for reducing dry shrinkage of semi-rigid materials are presented.
