An approach for the recycling of waste concrete powder as cementitious materials

초록

Recycled concrete powder, which was generated by crushing waste concrete, was reutilized as concrete material. The experiment intends to perform several tests for the exploitation of recycled concrete powder as cementitious material. The recycled concrete powder significantly influences the properties of mortar according to the type of recycled concrete powder, replacement ratio, and mix design. The flexural strength and compressive strength after 28 days of the mortar mixed with matrix recycled concrete powder was slightly larger than that of mortar using demolished recycled concrete powder. Thus, the use of recycled concrete powder will be promoted and realized through the utilization of self-consolidating concrete, pavement concrete, and roller compacting concrete.
