Research on recycled concrete and its utilization in building structures in China

Large quantities of construction and demolition(C&D)building waste are being generated as a result of rapid urbanization and natural disasters in China.An increasing awareness of environmental protection is escalating C&D waste disposal concerns.This paper presents a brief introduction to current shaking table test research in China on structures built with recycled aggregate concrete(RAC).Test structures include a cast-in situ frame model,a precast frame model and a block masonry building.The test results prove that it is feasible to use RAC as a structural material in seismic areas,with recommended modifications and proper design,especially in low-rise structures.This paper also presents several successful applications of RAC in civil and structural engineering projects in China,which will serve to promote RAC as a global ecological structural material.
