In the last few decades, Concrete consumption has become multifold and usage has enhanced in massive scale due to the rapid growth of infra sector. Generally, Concrete consists of cement, aggregate, and water; these ingredients become more expensive day by day and additionally hard to please and is increasing widely. During the process of making Ordinary Portland Cement (OPC) produces a large amount of greenhouse gases and the environment being polluted. To minimize the cement utilization and environmental issues is essential to switch the cement by another alternate materials such as pozzolanas. The various number of pozzolanic materials comes from industrial wastes are Groundz Granulatedz Blastz furnacez Slagz (GGBS), xFlyqAsh (FA), zSilicazFume (SF), Metakaolin (MK) etc are utilized in concrete. The excessive usage of natural sand in construction industry day by day , which leads natural sand is getting depleted .Therefore, it is necessary to replace natural sand in concrete by an alternate material either partially or completely without compromising the quality of concrete. Manufactured Sand (M-sand) is adopted to replace river sand. Concrete is strong in compression and weak in tension. Concrete is brittle and will crack with the application of increasing tensile force. To increase the tensile and flexural strength , fibres are added in concrete. The addition of fibres to concrete will result in a composite material that has properties different from those of un-reinforced concrete. The fibres in the concrete which are randomly oriented, arrests the cracks formation .It offers increasing toughness and ductility, tighter crack control and improved load-carrying capacity. Different types of fibres are available in the market for reinforcing concrete and they are steel, glass, acrylic, aramid, carbon, nylon, polyester, polyethylene, polypropylene, etc . To maintain the workability of concrete Water reducing admixture (super plasticizer) is used and to maintain less water binder ratio.The percentage of super plasticizer added in the concrete By trial and error method. An attempt is made in the present investigation to study on properties of fiber reinforced concrete of M40 grade made with OPC, GGBS, MK with different proportions and Natural sand is completely replaced with manufactured sand.qsteelu fibers are adding 1% of binder in every mix . The various mix proportions are M0, M1, M2 and M3 which contains 100% OPC, 80% OPC + 10% GGBS + 10% Metakaolin , 70% OPC + 15% GGBS + 15% Metakaolin and 60% OPC + 20% GGBS + 20% Metakaolin respectively. By casting requisite number of cubes, cylinders and cured in water with 7 days and 28days. Mechanical properties are determined such as fCompressivekstrength,sSplitdtensile strength tests and in addition to that durability properties are determined by conducting Water absorption and Sorptivity tests. Test results are of M40 grade is shows that the mix M2 contains 70% OPC + 15% GGBS + 15% Metakaolin is optimum for strength and durability criteria.
