AXIAL COMPRESSIVE BEHAIVOR OF FRP-CONFINED RECYCLED BRICK AGGREGATE CONCRETE

摘要：

　　Waste bricks are one of the largest sources of Chinas construction and demolition(C&D)waste.An effective way of utilizing waste bricks is to reuse them as recycled aggregate to substitute natural aggregate for fabricating new concrete.Recycled brick aggregate concrete(RBAC)generally exhibits inferior mechanical and durability properties compared with natural aggregate concrete(NAC)due to the relatively high water absorption and low strength of bricks.This paper proposes FRP jacketing as a new means to achieve much enhanced performance of RBAC.The test results show that the compressive strength and the ductility of RBAC can both be significantly enhanced by FRP confinement.The test results are also compared with a stress-strain model originally proposed for FRP-confined NAC.
