Abstract: Concrete is recognized as a quite breakable material when exposed to impact loading and normal stresses. Concrete tensile strength is nearly one-tenth of its compressive strength. As a result of which concrete members are not able to support such stresses and loads which mainly occurs in most concrete structures. So, we mainly reinforce it with such materials which help it to increase its tensile and flexural strength. Fibers are the material which helps to increase the toughness and durability of concrete and reduce plastic and drying shrinkage. As we know cement, sand and aggregate are three basic construction materials. Due to the huge demand for these materials, their deposits are scarce. So, we need to find the material which can replace them partially and fully. Stone quarry dust is material that may be used to replace sand partially and fully. In this study, the casting of moulds for various percentage of stone quarry dust (5%, 10%, 20%, 30%, 40%, and 50%) is carried and maximum value for stone quarry dust is obtained. After obtaining the max value of stone quarry dust at 10% it is replaced with various percentages of polypropylene fiber (0%, 0.1%, 0.2% and 0.3%). This study aims to investigate the limit up to which stone quarry can be replaced with sand for M35 grade of concrete and to investigate the combined effect of stone quarry dust (10%) and polypropylene fiber with varying percentage (0%, 0.1%, 0.2%, and 0.3%).
