Study on the Replacement of Construction &Demolition Waste Materials as Fine Aggregates inthe Production of Low Strength Concrete

ACLThe construction industry is searching for a more ecological material which can provide a good sustainability and also have the eco-friendly label. The quest to protect the environment has enabled researches to find alternate materials which can fit the concrete matrix to produce a concrete that can meet the demand of the construction industry. The purpose of this research is to substitute traditional materials with construction and demolition waste by keeping the same slump value and by replacing natural fine aggregates (NFA) with Construction and Demolition Waste (C&D) materials and investigate their properties on fresh and hardened concrete. To determine and compare the properties, different tests were performed to evaluate the workability, density, compressive strength, flexural strength and absorption of each concrete mix. The results demonstrated that, construction and demolition waste materials with a define slump range decreases the compressive strength and flexural strength, and the water absorption increases with increasing C&D content
