Abstract:

With existing disposal sites for concrete being rapidly exhausted and good sources of virgin aggregate depleting, the implication of using recycled concrete aggregate (RCA) in our infrastructure has gained importance. Pervious concrete pavements are an environmentally conscious alternative to traditional pavements. This work investigated using recycled concrete in pervious concrete, specifically the effects on the density, strength and permeability. Cylindrical specimens of pervious concrete with different percentages of RCA and conventional aggregate were cast. The coarse aggregate was substituted by 0, 10, 20, 30, 50, and 100% RCA. As percent RCA increased both compressive strength and permeability generally decreased. The strength and hydraulic characteristics of mixes examined in this study compared generally well with other studies on porous concrete without RCA found in the literature indicating that RCA. The results indicate that up to 50% substitution of course aggregate can be used in porous concrete without compromising strength and hydraulic conductivity significantly. Further testing evaluating freeze-thaw durability is necessary if the porous concrete with RCA is to be used in cold climates.
