Abstract

SCC is an innovative concrete that does not require any vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. SCC has favourable characteristics such as high fluidity, good segregation resistance and the distinctive self-compatibility without any need for vibration during the placing process and so noiseless construction. The control mix obtained by trial and error procedure. The mix is prepared replacing 15% to 30% of cement with Metakaolin and finding out the optimum percentage of Metakaolin. Polypropylene fibers of the range varying from 0.1 to 0.5% are added by keeping the optimum value of Metakaolin constant. The effects of Polypropylene fiber and Metakaolin inclusion on the fresh and hardened properties of self-compacting concrete are studied. Fresh properties of the SCC are tested comprising of slump flow, L-box height ratio and V-funnel flow time and hardened properties including compressive strength, flexural strength and splitting tensile strength are tested and compared with that of normal SCC. With the addition of Metakaolin and Polypropylene fiber the properties of SCC are enhanced.
