ABSTRACT

Now-a-days Demolished Concrete waste handling and management is a challenging job for all civil masterminds all over the world. Every year a lot of tons of construction concrete waste is produced through demolition of Structures. According to the Building Material Promotion Council (BMPTC), India generates an estimated 150 million tons of construction and demolition (C&D) waste every year. Utilizing this recycled aggregate is certainly an important step towards sustainable development in the concrete industry and management of construction waste. Recycling the Demolished Concrete will reduce the environmental pollution and protect the natural resources. Construction and demolished waste are generated due to natural disasters, or for future development the old buildings are replaced by new ones, and war inflicted damages. The use of recycled aggregate obtained from the waste concrete, as a component of the new concrete mixture, implies a thorough understanding of its fundamental properties. The main idea of the current research project is concentrated on utilizing the Demolished Concrete waste and reducing the generation of construction waste, and to investigate variability of natural aggregate properties and recycled aggregates properties, collecting Demolished Concrete from the building location. By performing some fundamental procedures like collecting, crushing and sieving for getting the aggregates of required size and shape. Eventually by conducting the physical tests and Mechanical tests on obtained recycled aggregates the properties are determined.

Keywords: Demolished Concrete waste, recycled aggregate, crushing, sieving, physical tests and Mechanical tests.
