SELF-COMPACTING CONCRETE USING RECYCLED COARSE AGGREGATE- A FEASIBLE SOLUTION FOR WASTE DEMOLISHED CONCRETE

Concrete is mainly used construction material around the world. Different types of concrete have been developed. In case of heavy reinforcement it is very difficult to make sure that whether formwork gets completely filled, compacted. This problem can be sort out with Self Compacting Concrete(SCC) Self Compacting Concrete is the kind of concrete which does not require vibration at the time of placing, also it is having the capacity to flow in congested reinforcement under its own weight. This study gives an experimental investigation of fresh and hardened state properties of Self Compacting Concrete made with recycled coarse aggregate. In this study tests on coarse aggregates are performed and after that M30 grade of concrete is prepared. Five trial mixes with replacement of natural coarse aggregate with replacement of recycled coarse aggregate in percentage replacement of 0%,25%,50%,75% and 100% are prepared. The effect of recycled aggregate on fresh properties, compressive strength properties of SCC is studied in this research. All the tests gives satisfactory results. It is observed that recycled aggregate can be used in the production of Self Compacting Concrete (SCC) without any significant reduction in its properties.
