As we know concrete comprises of cement, fine aggregates, coarse aggregates and water. The easy access to these construction resources has no doubt boosted the construction throughout the world. But the rapid depletion of these resources and increasing cost is emerging as an attention seeking issues. Due to which construction industries are facing crises for the easy availability of these resources but we would like to make prime emphasis on fine aggregates as our research moves that way. At many place digging rivers for sand has been made illegal. So it's becoming a tough job to get river sand at cheap rate .That is why various alternatives is being adopted to counter this problem such as reuse and recycling of construction waste. So keeping all the facets in our mind we begin with our project of reuse of recycled demolished concrete. In this project we replaced fine aggregates with the demolished concrete in the range 0%, 10%, 20%, 30%, 40%, 50% using M25 grade of concrete. Sieve analysis is also performed for recycled demolished concrete and coarse aggregates. The prepared concrete mix is compared and test in terms of compressive strength, tensile strength and flexure test to conventional concrete. The test was performed at 3, 7 and 28 days in order to evaluate the strength properties. Key words: Compressive strength, Split tensile strength, Flexural strength, recycled demolished concrete.
