The self compacted concrete is an innovative product in civil engineering field of India. The necessity of this product was felt by civil engineers to overcome in the issue of workmanship, in structural concreting of heavily reinforced sections in execution of concrete. The introduction of SCC in the precast concrete industry was successful, with regard to application in situ; the development is slower because of the sensitivity of the product.The development of concrete that can be compacted in to every corner of a formwork by means of its own weight and without vibration is reviewed.SSC was developed to achieve durable concrete structures.This type of concrete has used by large construction companies.In recent years SSC has gained wide use for placement In reinforced concrete structures with difficult casting conditions. Sludge is a major issue since the they are the obtained from sewage and industrial waste where it causes many problems, so it can be used as admixture to the concrete because it attains more strength. In this paper, the mechanical properties of SCC in comparison to conventional concrete and concrete using sludge were discussed. The compressive strength results of hardened concrete showed that SCC gained strength slowly compared to theconventional cement concrete due to the presence of admixture and it’s 28 days strength was lower than conventional cement concrete ,but SCC eventually had potentials of higher strength beyond 90 days. Finally the effect of water cement ratio on the plastic properties of SCC was quite negligible compared to conventional method.
