Study On Fresh And Harden Properties Of Self Compacting Concrete Using Recycled Bituminous Road Aggregates

Abstract

Self compacting concrete or self consolidating concrete has high potential application for congested reinforcement member with good workability. Self compacting concrete (SCC) is normally being used for construction of high rise buildings and industrial structures. This paper presents the methodology and test to be performed on self compacting concrete prepared by combination of natural coarse aggregate (NCA) and recycled bituminous road aggregate (RBRA). The study has to be conducted in order to find out the amount of percentage of coarse aggregate to be replaced by RBRA and also to find out the alteration in the fresh and hardened properties of self compacting concrete with such combinations. The study also help us to investigate, what will be the effect on self compacting concrete if some percentage of cement is replaced by fly ash. The overall aim is to find out the percentage to which replacement of NCA with RBRA can be raised in order to get concrete of desired strength without much alteration in its properties.
