Effect of notch-depth ratio on fracture properties of light weight self compacting concrete beam

The utilisation of recycled concrete aggregate (RCA) in Self-Compacting Concrete (SCC) has the potential to reduce both the environmental impact and financial cost associated with this increasingly popular concrete type. However, to date limited research exists exploring the use of coarse RCA in SCC. The work presented in this paper seeks to build on the existing knowledge in this area by examining the workability, strength, and fracture properties of SCCs containing 0%, 25%, 50%, 75%, and 100% coarse RCA. The experimental programme indicated that at RCA utilisation levels of 25% to 50% little or no negative impact was observed for strength, workability, or fracture properties, with the exception of a slight reduction in Young’s modulus.

Light Weight Aggregate

The density of concrete less than that of nominal concrete achieved by any means is referred as Light weight concrete. Circulated air through Concrete, Light Weight Aggregate Concrete, Foamed Concrete are different types of Light weight concrete. In this research study, the density of the concrete has been reduced by replacing the coarse aggregate by the pumice stone as light weight coarse aggregate. The major advantage of this study is to reduce the risk of seismic damages of the structure by reducing the self weight of the structure. The decrease in dead load of structure because of the utilization of LWC additionally brings about reduction in the cross segment of other auxiliary individuals such as beam, column and foundation. The pumice stones have huge number of voids and have moderately higher warm protection than the ostensible aggregates. The objective of this research is to obtain light weight concrete having low unit weight and an optimum compressive strength. The Nominal concrete and the light weight concrete is prepared and the tests were led to decide the mechanical properties and compressive quality, its flexural capacity in beams
