Properties and Characteristics of Recycled Concrete Aggregate A concrete pavements strength and performance is very dependent on the aggregates used to produce the concrete. Recycled concrete aggregates are different in many ways from virgin aggregates as shown in Table 1. Table 1. Comparison of typical virgin aggregate and recycled concrete.

    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.
