AN EXPERIMENTAL STUDY IS CONDUCTED TO DETERMINE HOW CHARACTERISTICS OF SCC METAKAOLIN AND FLY ASH AFFECT THE MECHANICAL

Due to the absence of compaction, self-compacting concrete (SCC) has better characteristics and enhances productivity and working conditions. SCC is suited for installation in crowded reinforcement structures without causing vibration, and it aids in producing higher-quality surface finishes. However procedure of Metakaolin and Fly ash as an effective pozzalonic material which causes great enhancement in the pore structure, also compatibility is precious by the characteristics of materials and the mix proportions, it becomes necessary to evolve a procedure for mix design of SCC. The purpose of this experimental investigation is to determine how metakaolin and fly ash affect the mechanical characteristics of self-compacting concrete. In this case, fly ash is replaced with 30% in order to increase strength, and for that amount of fly ash (FA), metakaolin (MK) is substituted with percentage weights of cement, i.e. (0%, 5%, 10%, 15%, 20%). The outcomes demonstrated that the addition of metakaolin to fly ash improves the mechanical characteristics of self-compacting concrete. Additionally, the sample's results from the binary SCC test are contrasted with those from the standard test using cement, metakaolin, and fly ash
