不同强度砂浆界面过渡区对再生骨料混凝土性能的影响
Influence of Mortar Transition Zone with Different Strength Class on Recycled Aggregate Concrete
摘要
Abstract
In this research, the experiment aimed to investigate the influence of surface mortar strength and adhesive rate around coarse aggregate on recycled aggregate concrete. Different strength class concretes were produced with surface mortar strength and adhesive rate changing. The strength and carbonization tests were carried to evaluate the recycled aggregate concrete properties. The experiment showed that for lower strength class recycled aggregate concrete with higher strength parent concrete, the strength of recycled aggregate concrete and ordinary concrete were nearly the same. The effect of surface mortar strength and adhesive rate around coarse aggregate on recycled aggregate concrete was lower, while the carbonization depth of recycled aggregate concrete was higher than ordinary concrete. However, for higher strength and the same strength class recycled aggregate concrete with lower strength parent concrete, there were big differences between recycled aggregate concrete concrete and ordinary concrete.The effect of surface mortar strength and adhesive rate around coarse aggregate on recycled aggregate concrete was higher, and carbonization depth was increasing.关键词
