Abstract: With concrete being the most ubiquitous material used in the construction sector, rampant exploitation of natural resources has been observed in the form of plummeting availability of natural aggregates, which account to most of the volume of concrete. On the contrary construction and demolition waste obtained from the demolition of buildings end up accumulating space at landfills and contribute to environmental waste. To address the following problems, recycled aggregates serve as a solution. These aggregates have the advantage of reducing transportation costs as well as the amount of Carbon dioxide. But these aggregates aren’t used on a large scale owing to the inferior quality of concrete produced. The research presents an experimental investigation to study the mechanical properties of concrete (compressive and split tensile strength) and compare the strength of conventional concrete with concrete having untreated as well as treated aggregates. The recycled aggregates were substituted with virgin aggregates in different percentages of 25, 50, 75 and 100. Treatment of the recycled aggregates was done to enhance its properties, thus utilizing its functionality. Concrete specimens were casted using recycled aggregates, untreated aggregates and treated recycled aggregates separately.
