Abstract

Abstract: This paper analyzed the cube compressive strength of concrete containing recycled aggregate as part of coarse aggregates and rubber particles as part of fine aggregate, simultaneously. The effect of content of both aggregates on concrete compressive strength was studied. 25 sets of samples were made with a constant water/cement ratio of 0.39. Cube compressive strength of different samples at age of 28 days were obtained in accordance with relevant standard. Influence of replacement ratio of recycled aggregate and rubber on strength was investigated basing on the analyses of testing data and microstructure inspections, respectively. Results indicate that both recycled aggregate and rubber particles weaken the compressive strength of concrete while rubber particles plays a more important role. Replacement of fine aggregate over 20 vol% by rubber particles should be used carefully.
