Abstract: A self-compacting concrete (s.c.c) is a special concrete which settles itself without any vibration due to its own mass and self-weight. This will happen due to use of special admixtures which have tendency to increase the flow of concrete by reducing the viscosity nature. This particular type of concrete was developed by the japan researchers in 1988. Later it was modifies and developed in many parameter’s by UK and U.S.A researchers. This particular thesis is about the improvement of performance of the S.C.C by replacing the fines and cement of the aggregates by the waste products that obtained from the different industries. The fines are replaced partially by crushed sand obtained as quarry waste and the aluminium slag that obtained from many industries as a waste product is partially introduced as binding material By using this S.C.C the problems that are facing by the construction industries during the placement of the concrete will solve. Now days the structures are designed and made as heavy reinforced structures where the sizes of structural elements are restricted due to architectural and some structural considerations. So the concrete that poured in those elements shows the voids and honey combing it can be prevented by using this S.C.C. not only the improvement of the strength but also the construction time and cost also gets reduced by using this product, because with this material no need of vibration. It reduces the time of construction and cost regarding vibration equipment and labor. But the main problem while preparing s.c.c is to select the proper admixture to prevent the cracking and shrinkage issues. This type of concrete requires 20-25 percent higher matric paste when compared to conventional concrete. This thesis works on mainly preparing the most feasible mix for s.c.c with the partial replacement of fines and cement by above mentioned materials which makes the matrix still in plastic state without altering the original properties of the concrete. The second task is to prepare the specimens for different strength tests and like compression and tensile and bending parameters check along with the considering the shrinkage issues.
