The Influence of Matrix Concrete on The Strength of Recycled Concrete
Recycled coarse aggregates obtained by crushed concrete were used for concrete production in this study.Four different recycled aggregate concretes were produced; made with 50% of recycled coarse aggregates of four intensity levels.The damage of the recycled concrete is the bond failure of the interface of aggregate and mortar,which is basically the same as the damage process and damage mechanism of the natural concrete.The strength of recycled concrete was influenced by matrix concrete.When the strength grade of matrix concrete is less than C35,the recycled strength of concrete will be inferior to that of natural concrete basically.But when the strength grade of matrix concrete is higher than C35,the recycled concrete strength will be higher than that of natural concrete.
