Flexural behaviour of self compacting concrete beams modified using recycled concrete waste aggregates

Abstract

This study presents an investigation on the flexural behaviour of normally vibrated concrete and self-compacting concrete beams subjected to loading tests. Seven specimens were cast to investigate the flexural behaviour. This experimental analysis mainly varied the parameters such as (1) Percentage of coarse aggregate replacement (RCWA), and (2) percentage of Steel fibres. Results are exhibited in terms of flexural strength, stiffness, failure modes, and deflection curves. The test results revealed that RCWA could be successfully used in SCC. The flexural behaviour of beam decreased with the addition of RCWA. However, the addition of RCWA in combination with SF in SCC significantly improved the overall flexural behaviour. Finite element model also developed to study the behaviour of beams produced by SCC with RCWA content.
