本文以石灰土类、石灰粉煤灰类、水泥砂砾类三种典型半刚性材料为对象,较系统地研究了半刚性材料的温度收缩和干燥收缩机理、介绍了半刚性基层收缩规律的研究结果,提出了提高半刚性基层材料抗裂性能的基本途径和方法。
In this paper, three typical semi-rigid materials, lime soil, lime fly ash and cement gravel, are studied systematically to study the mechanism of temperature shrinkage and drying shrinkage of semi-rigid materials. The results of research on the shrinkage law of semi-rigid base are introduced , Put forward to improve the semi-rigid base material crack resistance of the basic ways and methods.
