Flexural Behaviour of RC Beams with Recycled Aggregates

Abstract

Continuous raw material demand was increased in concrete productions which require good quality and cost efficient alternative materials like Recycled Coarse Aggregate, M Sand and Glass as aggregate. This paper reports the behaviour of concrete using Glass aggregate as Fine Aggregate and Recycled aggregate as Coarse Aggregate replacement in concrete up to 15% and 30% respectively. In this project work, the concrete grade M25 was selected and IS method was used for mix design. The properties of Cement, M-Sand, Natural Coarse Aggregate, Glass as Aggregate and Recycled Aggregate were investigated. The Beam Specimens were casted with and without C&D waste (Coarse Aggregate Replaced with Recycled Aggregate at 30% and Fine Aggregates replaced with Glass Aggregate at 15%). Vibration Analysis was made by using FFT analyser to determine acceleration characteristics. The work is focused on possible conservation of natural resources by substituting with waste material by suggesting a possible reuse option for Construction waste.
