In the construction industry, a lot of waste discharged, for example steel, concrete et al. In order to waste concrete is consist of mortar and coarse aggregate, it is impossible to separate them completely. So waste concrete crush up, and are using as base coarse material. But road construction is reducing now. From the point of view, when waste concrete using as coarse aggregate, these chemical and mechanical properties are unknown. Therefore we will examine that mixing fresh concrete to broken their blocks (20～50mm diameter), and hardening concrete containing waste concrete will be able to fulfill function structural member.
