Abstract: The demand of Natural River Sand is increasing day by day due to the usage of concrete increased. Many Researches are made by many scientists for a suitable replacement of natural river sand as a fine aggregate. The aim of our project is to use demolished concrete waste as fine aggregate. In our project, natural river sand is fully replaced by demolished concrete waste as fine aggregate. The comparison between the properties of natural river sand and our demolished concrete waste is done. The specimens are cast and compressive strength test and split tensile strength test is done. The test results are compared to conventional concrete with demolished concrete waste. The results are shown by graphically.

Keywords: Demolished Concrete Waste, Fine Aggregate, Specimen and Casting, Compressive and Split Tensile Strength Test.
