Engineering properties of porous concrete made of sustainable aggregate

Abstract

The effect of using different types of aggregate on engineering properties of previous concrete is experimentally evaluated in this study. For this purpose, a total of four concrete mixes are cast and tested. The main parameters studied in this study are the aggregate type (natural and recycled) and aggregate size. The recycled aggregate was provided from damaged pavement roads at Amarah city. The flexural and compressive strength, infiltration, and permeability of pervious concrete are recorded throughout the study. The results of study revealed that the mechanical and physical properties of previous concrete made of recycled aggregate confirms with the international specifications. Furthermore, the conclusions appear the ability of using recycled aggregate from damaged road pavements as aggregate for producing the pervious concrete have an acceptable engineering properties. The utilizing of recycled aggregate contributes to reduce the pollution and represent as a kind of sustainability of this type of concrete materials.
