Abstract
Abstract: Sprayed steel fiber reinforced recycled concrete (SSFRC), as a green product of small particle size recycled aggregate (RA), was tested for compressive performance using an electro-hydraulic servo pressure testing machine. The replacement rate of RA, the volume ratio of Steel Fiber (SF), and the strain-stress curve of SSFRC were studied. The relationship between the axial compressive strength and the compressive constitutive model of SSFRC was proposed, and theoretical support for expanding the engineering application of recycled concrete (RC) was provided.
