Abstract: “The Dolomite Powder (DP), as a filler material has been used in the Self Compacting Concrete (SCC), which regulates the segregation of fresh concrete as well as rendering favorable impacts on the deformability of the SCC. The current study addresses the investigation of effects of locally available DP along with the proportions of locally available Fly Ash (FA), on the properties of SCC. The other aspect of this research work deals with the search of economical filler material to be used in concrete without compromising the strength of concrete and within the prescribed guidelines of European Federation of National Associations Representing producers and applicators of specialist building products for concrete (EFNARC).The specimens of concrete were cast using variousmix ratios of DP and FA. On the basis of the results obtained, it was indicated that with the use of DP along with the proportions of FA, the SCC fulfilled the criteria of EFNARC both in the fresh state and the hardened st”
