Cinder being a highly pyroclastic material possesses mass less than that of the incentive aggregate. Apart from being vitric in nature. Cinder dust can be a replacement for fine aggregates for both construction industries as well as for road construction. The availability of natural river sand is becoming less in the environment hence there is a necessity to find replacement for natural river sand. This can be achieved by compensating the industrial wastes such as slag, cinder & manufacturing sand. Here in this research, natural sand is replaced partially with cinder as fine aggregates, in this regard, the replacement is so done to enhance the desired property of mortar. Commonly the natural sand is replaced by cinder sand but no emphasis on the size of the fine aggregate (fineness modulus) is taken into consideration which is based on the theory that property of the material changes due to variation in the size The properties of cinder sand is compared with natural river sands per IS 383. In this research sample cubes of standard size 70.6mm x 70.6mm x 70.6mm specimens have been casted for 1:3 proportion with replacement of sand with cinder by weight. The resultant samples have been tested for their strength and quality parameters to check the suitability of application of the above-mentioned replacement of natural aggregate with cinder to cement sand mortar.
