Study on Durability Characteristic Strength of Recycled Waste Concrete

In developing countries, with the increasing population, both economy and pollution free environment in construction industry are of principal importance in order to meet the inevitable human needs of multifarious forms. Thus, use of waste aggregates in the production of new type of concrete, which plays an important role in the construction industry, for fulfilling the demand of aggregates. Most of the waste materials are generated from industrial waste and demolishing waste. Hence, recycling, reuse and substitution of this waste appears to be an effective solution and most appropriate decision. In the present research work desirable characteristics of recycled aggregate concrete were studied. The experiments were conducted for different ages of concrete such as 7 and 28 days to assess the compressive and split tensile strength. The workability properties of mix are evaluated by workability tests such as sump flow test, V- funnel, U- box and L- Box test. It addresses experiments on various mixes of self compacting concrete – One with fresh coarse and fine aggregates, while the others with replacement of 20%, 40 %, 60%, 80% And 100% recycled fine aggregates.
