COMPARISON BETWEEN TRADITIONAL CONCRETE AND CONCRETE MADE UP OF WASTE CONCRETE DEBRIS

As we all know that making of fresh concrete is uneconomical today as the fresh raw material or material mix for concrete in costly day by day. In this project, we use old concrete demolition debris in making fresh concrete by introducing this debris in optimum percentage in mix of concrete. This use of concrete demolition waste in our project also helps in Solid Waste Management which is today in construction world one of the major problem. Therefore, by using demolition concrete in fresh concrete we minimize the construction cost of construction cost of fresh concrete. In this project we work as Hardness, and toughness of old concrete debris, workability and compressive strength on fresh and hard concrete, respectively by adding 5%, 10%, 15%, 20%, and 25% of old demolition concrete
