Partial Replacement of Cement by Kota Stone Slurry in Mortar

S. C. Harshwardhan, Pawan Kalla, Ravindra Nagar, Pradeep Kumar Gautam



Kota stone is one of the lime stones which is found in Kota, Jhalawar, and Chittor districts of Rajasthan. It is a very fine-grained siliceous calcium carbonate rock of sedimentary nature. During cutting and polishing process, a lot of material remains unused, and this waste may be called as Kota stone cutting and polishing waste. The disposal of Kota Stone Slurry (KSS) from the Kota stone industry is one of the major environmental problems today causing bronchial, vision and skin disorders in the nearby inhabitants. This paper presents a study on mortar mixes containing Kota stone slurry as a partial replacement for cement. Total seven mortar mixes were evaluated on the basis of compressive, flexural and tensile strength. Portland Pozzolana Cement was used for the study; it was replaced by KSS between 0 and 30% in mortar mixes. For testing of mortar mixes prepared with replacement of cement by KSS, ASTM and BIS standards were used. Improvement in strength was observed up to 10% KSS replacement which was attributed to its filler effect.
