Aug 19, 2020  Methodology. Recycled concrete aggregates are generally more porous than the primary coarse aggregates. The main property of pervious concrete is its permeability, so the part of fine aggregate can be reduced and the part of natural aggregate can be replaced with recycled concrete aggregate to enhance permeability without much affecting the strength of the concrete.

Resistance to fragmentation of recycled concrete aggregates

Aug 10, 2016  This work deals with the characterization of fragmentation of recycled concrete aggregate (RCA) by the Los Angeles test. The standard testing procedure for the Los Angeles index requires the measurement of the mass passing 1.6 mm after 500 revolutions of the drum. Questions arise on the significance of this measure for RCA as the resistances of the mortar, of the original aggregate
