In order to promote the engineering application of the recycled aggregate of construction waste, the natural aggregate was substituted by regenerated fine aggregate for the research parameters to configure four groups of recycled aggregate concrete.The cubic and prismatic compressive strength specimens were made.Based on the compressive strength tests for four groups of recycled aggregate concrete at different ages, the effect of the regenerated fine aggregate substitution ratio on the compressive properties of brick-rich recycled concrete was studied.The results show that the compressive strength of recycled concrete decreases under 28d age with the increase of the replacement rate of regenerated fine aggregate, but the effect is less at 3d and 7d.The calculation model between axial compressive strength and cuboidal compressive strength was obtained considering the influence of regenerated fine aggregate substitution rate.
