Comparison in strength of pervious concrete block by using natural course aggregates and plastic coated course aggregates

Abstract

This paper presents comparison in strength of pervious concrete block by using Natural course aggregate (NCA) and plastic coated course aggregate (PCCA). Pervious concrete is a concrete which consists of course aggregate and cement paste. In this paper concrete made by NCA and PCCA. Previous studies indicate that pervious concrete has lower compressive strength capabilities than conventional concrete. This work investigated prior studies on the compressive strength on pervious concrete as it relates to water cement ratio, aggregate size and compaction and compare those results with results obtained in laboratory experiments conducted on sample of pervious concrete block made by NCA and PCCA. The present study investigated the use of waste plastic for the modification of properties of aggregate and compressive strength of PCCA pervious concrete. The plastic waste thoroughly mixes with hated aggregates forming a layer on the surface of the Natural aggregates. This PCCA aggregate tested for impact test, crushing value, specific gravity and water absorption. It has been found that there is significantly improvement in the properties of plastic coated aggregate and the compressive strength of PCA cubes is slightly less than the NCA cubes.
