説明

Coarse aggregate adhered mortar and lumps of mortar are produced from mixed concrete for the experiment, influence of existence form of mixed mortar on the properties of recycled coarse aggregate concrete is examined. As the result, it is confirmed that compared to adhered mortar, residual lumps of mortar have a profound influence on compressive strength, static modulus of elasticity and length change of recycled coarse aggregate concrete. Meanwhile, recycled coarse aggregate concrete is equivalent to splitting tensile strength of ordinary coarse aggregate concrete. In addition, it is confirmed within the study that water-cement ratio of the original concrete have little influence on the properties of recycled coarse aggregate concrete.
