The Performance Characteristics of Concrete with Over Burnt Bricks as Partial Replacement of Coarse Aggregate

Abstract

To contradict the demand of natural stone aggregates this research aims to utilize the Over Burnt Clay Bricks (OBCB) as alternative to coarse aggregates. In this study the possibility of utilizing crushed over burnt clay bricks as a replacement of coarse aggregates in M30grade concrete. Trial mixes were prepared using crushed over burnt clay bricks as coarse aggregate at various replacement levels. Experimental        investigation was   carried to enumerate the mechanical   properties of the concrete by testing the workability, water absorption and density. The test results showed that concrete made by over burnt clay bricks in concrete as 50% replacement of coarse aggregate, gives the higher compressive strength of 46.27MPa.
