Effect of different substitution of natural aggregate by recycled aggregate on performance characteristics of pervious concrete
The objective of this research was to incorporate recycled aggregate into pervious concrete to create a very sustainable concrete product for many applications. The research methodology interested replacing natural aggregate with recycled aggregate in the pervious concrete production at 4 different replacement levels of 25, 50, 75 and 100 %, with two different water-to-cement ratios of 0.27 and 0.32. Single sized recycled and natural aggregate, passing from 12.5-mm sieve and retained on 9.5-mm sieve, were used in the manufacturing of pervious concrete. Totally ten different concrete mixtures were produced and each of the concrete batches was tested for dry density, porosity, compressive and splitting tensile strength, water permeability and abrasion resistance. The properties of pervious concrete produced with recycled aggregate were also evaluated by statistical technique, namely GLM-ANOVA. The experimental results showed that the properties of pervious concrete were significantly affected by using recycled aggregate. Substituting the natural aggregate with recycled aggregate resulted in a considerable increment in permeability coefficient. However, it was observed that the mechanical properties of such concretes were adversely influenced up to a certain degree.
