将废弃陶瓷破碎筛分制成再生骨料以不同比例(50%、80%、100%)代替相应天然骨料配制混凝土.在对废弃陶瓷再生骨料混凝土和天然骨料混凝土的力学性能进行对比研究的基础上,进一步对再生骨料与水泥石的粘结性能进行了对比研究.研究表明:混凝土中虽然随着再生骨料代替量的增加,力学性能有所下降但下降幅度大都没超过15%,且表现出较好的界面粘结性能,因此,废弃陶瓷再生骨料完全可以代替天然骨料用于混凝土的配制.

This paper is focused on preparing concrete by crushing the ceramic wastes to make the recycled aggregate to substitute for the natural aggregate in different ratios(50%、80%、100%).The comparison of the mechanical performances between recycled ceramic concrete and normal concrete is conducted,as well as the interfacial zone between recycled aggregate and masonry mortar.Results show that the mechanical performances of recycled ceramic concrete decrease no more than 15%in comparison with that of natural concrete though the performances exhibit monotonically decreasing as the recycled ceramic aggregate ratio increases,and the bonding performance of interfacial zone is better.Therefore,the recycled ceramic aggregate can fully substitute for the natural aggregate to prepare concrete.
