Effectiveness of Construction and Demolition Wastes on Mechanical Characteristics of M-30 Grade Concrete

The industrialization production rate increases the disposal demand of waste materials. The land disposal method for disposing the waste materials is one of the conventional methods requires a large area of land, but now a days due to lack of land availability these waste materials used as a construction material in various civil engineering applications.In recent years, Construction and Demolition Wastes (CDW) are increasing day by day and these are the wastes which influence our natural environment. To reduce the impact of these types of wastes, a study was conducted in laboratory and targeted to attain sustainability by reusing waste demolished concrete or recycled aggregates up to the optimum use. For examine the efficiency by RA, different percentage of RA replace with natural aggregate (0%, 20%, 40%, 50%, 60%, 80%, 100%) and evaluated the compressive strength of concrete cubes at 7and 28 days
