Abstract :SCC is a type of concrete that can be placed in the form work and it passes through any obstruction by its own weight and does not require any vibration. Modern application of SCC is focused on high performance, better and more reliable and uniform quantity. Recognizing the lack of uniformity and complete compaction of concrete by vibration, researches at the university of Tokyo, Japan, started in late 1980’s to develop SCC . By the year 2000, the SCC has become popular in Japan for prefabrication products and ready mixed concrete. The present study focuses on utilization of quarry dust and Metakaolin in SCC as a partial replacement of fine aggregate and cement respectively. Quarry dust is a by-product from the crushing process during quarrying activities is one of such materials. In recent days there were also been many attempts to use Metakaolin, it is not an industrial by product. Metakaolin has a partial replacement for cement to have higher workability, long term strength and to make the concrete more economically available. The present experiment is carried out to investigate the fresh and hardened properties of Self Compacting Concrete with 0 to 30% percentage of quarry dust as a replacement for fine aggregate and Metakaolin as partial replacement of cement. In this project, an attempt has been made to study the fresh and hardened properties such as flow ability, passing ability, compressive, tensile and flexural strength of Self compacting concrete.
