Experimental Research on Recycled Aggregate

2012-4-26  Recycled aggregate could be used to make recycled aggregate concrete for pavement if its technical specification conforms to the requirements of the standard of cement concrete pavement for highway (China) (JTGF30-2003). Consequently, recycled concrete aggregate is a good economic resource and great method for future development.

The compressive strength was 20.09 and 24.27 MPa, respectively for the concrete made by recycled brick aggregate and natural brick aggregate at 28 days. By using 10%, 15%,and 20% blast furnace slag with recycled brick aggregate, the compressive strength at 28 days was found to be 21.81, 24.52 and 25.30 MPa, respectively.

Efects of using recycled concrete of dlferent qualities as coarse aggregate upon the strength and deformation of concrete are reported. Tests on the aggregates showed that the recycled concrete aggregates have lower specific gravity and higher absorption capacity than the original crushed granite aggregate.

The effects of coarse recycled concrete aggregate on freeze–thaw resistance, mechanical performance and transport properties of self-consolidating concrete (SCC) were investigated. Recycled concrete aggregate (RCA) was substituted for crushed coarse limestone aggregate as 0, 20, 40 and 60 wt% of limestone aggregate.

Mortar mixtures containing more than 50% recycled concrete aggregate showed higher sulfate resistance than the control mixture. This was attributed to the accumulation of ettringite in pores of the RC aggregate resulting in lower expansion.
