This paper deals with the effect of cement replacement by activated clay. The increased use of concrete creates an impact on the environment because of the emission of greenhouse gases. Also, the high usage of cement in concrete increase the carbon foot print level, leading to global warming. Concrete being the second largest utilized material after water and researches are aiming to reduce its consumption. This paper focuses on the reduction of the cement usage by replacing it with activated clay. Clay being abundantly available is used as an alternate to cement since it possesses pozzolanic nature. To enhance the properties of clay it was chemically activated before being used in the mix. On the other hand, the efficiency of Fiber Reinforced Concrete-FRC is far superior to the plain concrete. To improve the mechanical properties of concrete Nylons fibers are used in the mix. Nylon fibers has high strength to weight ratio and good abrasion resistance. This paper studies the effective replacement of cement with activated clay by 50% and the same was partially replaced with 2.5% and 5% of fly ash and nylon fiber. The mechanical properties such as compressive strength, spilt tensile strength and flexural strength were tested after 28 days of curing. The test results indicate that there is a significant increase in the compressive and flexural strength whereas a decline was observed in tensile strength.
