摘要
针对普通混凝土存在的收缩问题,提出了一种生态混凝土,通过对生态混凝土进行室内干燥收缩、温度收缩试验,得到生态混凝土的干缩率、温缩系数,全面了解生态混凝土的收缩性能,为生态混凝土用于高等级长寿命路面结构提供理想的基层材料和设计依据。
Aiming at the shrinkage problem of common concrete,an ecological concrete was put forward,the shrinkage ratio and thermal shrinkage coefficient of eco-concrete are obtained,and the shrinkage performance of eco-concrete is fully understood,which provides ideal base material and design basis for eco-concrete used in high grade and long life pavement structure.
