Abstract: C30 grade concrete was prepared to produce the recycled aggregate and the basic properties of recycled aggregate were investigated experimentally. Then the recycled coarse aggregates with different natural coarse aggregates replacement ratio were used to produce recycled self-compacting concrete. The cube compressive strength and elastic modulus of recycled self-compacting concrete with different recycled coarse aggregate replacement ratio were tested respectively, the replacement ratio of recycled aggregate were 0%, 50%, 70%, 100%. The results indicate as follows: with the increase of recycled coarse aggregate replacement, the workability of recycled self-compacting concrete deteriorates; the cube compressive strength and elastic modulus of recycled self-compacting concrete reduce by 15% and 20% respectively.
Keywords:Recycled self-compacting concrete, Recycled coarse aggregate, Replacement rate, Compressive strength, Elastic modulus
