Concrete plays a vital role in the construction industry and on the other hand River sand, one of the essential material used in the concrete, has become expensive and also a scarce material. Due to increase in its usage depletion of sand deposits is occurring. Quarry Rock Dust (QRD), a by-product from crushing process during quarrying activities is one of the substitute materials for the natural river sand. In general, concrete is strong in compression & weak in tensional property. In this research, to increase the tensile property of Concrete, Glass Fibers are added with dosage of 1kg per m3 of concrete. In this investigation, an attempt is made to introduce the QRD in a percentage variation and to quantify the optimum usage of QRD in replacement to Natural Sand for Fiber Reinforced Self Compacting Concrete (FRSCC).Compressive Strength & Split Tensile Strength Tests were conducted to study the Mechanical Properties of FRSCC for the replacement of Natural Sand with QRD. It is observed that; at 40% replacement of Natural Sand with QRD, Target Strength is achieved.
