One of the well know and commonly used construction material is concrete. Due to the requirements of high quantity of concrete study on high performance concrete is gaining the importance to obtain the required properties of concrete by limiting the quantity and not sacrificing the required quality and also maintaining the cost efficiency and because cement is mostly used in concrete and production of concrete is not ecofriendly as it releases lots of carbon dioxide and hence research are being done to replace the cement in the concrete ,some of the replacements known are ,fly ash, silica fume and metakaolin etc. .Many researchers have used these types of waste products which were considered as waste materials in concrete and conducted many tests and found that these admixtures helped to boost the properties of the concrete greatly and hence This project also examines the properties changes in the high performance concrete(HPC) on compressive strength and the mechanical behavior of concrete made of fly ash and silica fume and Metakaolin, each of 0% ,5%,7.5% and 10% to the weight of cement. and fibers (Polypropylene Fibers and steel fibers) by referring to various articles which have been mentioned in the literature .Hence Specimen were casted under laboratory conditions with high quality materials by considering a constant water cement ratio and varying percentage of admixtures and also water binder ration and they were cured properly and tested for 7th and 28th days strength test such as compressive strength test, split tensile strength test and flexural strength tests were done on specific machines the results were tabulated and concluded

Key Words - Metakaolin, Silica fumes, Polypropylene fibers, Fly ash, Compressive strength, Steel Fibers, Flexural strength, Split tensile strength
