Development of Sustainable Concrete Using Construction and Demolition Waste

ABSTRACT Waste from construction and demolition accounts for a significant portion of global solid waste, with the majority of it ending up in landfills. Processing this debris and using it to make fresh concrete is a useful and profitable approach to manage it. Effective methods for utilising construction and demolition debris in concrete have been investigated by researchers. The study aimed to test the quality of recycled materials by evaluating their strength, water absorption, density, and the type of concrete they can produce. Compared to natural coarse aggregates, recycled aggregates from leftover concrete are heavier, more angular, and absorb more water. Strength and load-bearing capacity are enhanced as a result. To improve workability and examine their endurance, more research is necessary. This study explores the properties of recycled aggregates and focuses on developing concrete mixes incorporating them to minimize the environmental impact of the construction industry. It also compares concrete made with recycled and natural aggregates to evaluate their strength, Durability and Workability. We replaced natural aggregate concrete with 100% recycled aggregate concrete. Natural aggregate concrete has a higher compressive strength than recycled aggregate concrete.
