Newly developed cementitious material, Reactive Powder Concrete (RPC), firstly developed by Richard and Cheyrezy in 1990’s at Bouygues Laboratory,and is recognized as a revolutionary material that provides a combination of ultrahigh strength and excellent durability. RPC is a composite mixture of cement, silica fume, natural sand, quartz powder and steel fibres.On the other hand, Generation of Industrial Waste and its disposal is the biggest problem all over the Globe. However, the use of waste in concrete can be a good scope. Locally available industrial waste (Rajkot, Gujarat) used in the study is used foundry sand. Also another waste material used in the study is Fly ash.In this paper, the effect of combination of the two industrial by-product i.e. Fly ash and Used Foundry Sand on the Split Tensile Strength of Reactive Powder Concrete is presented. The results shows that Cement can be replaced by fly ash upto 15% along with the replacement of natural sand by foundry sand up to 20% gives considerable strength along with economy.
