PERFORMANCE EVALUATION OF CEMENT MORTAR BLENDED NANOFIBRILLATED CELLULOSE

Abstract

This paper focuses on the effect on rendering cement mortar by addition of aqueous Nanofibrillated Cellulose. For preparation of the mortar mix crushed sand was used. The Nanofibrillated Cellulose made from cotton linter were added in the percentage of 0.32%, 0.64%, 0.96%, 1.28% and 1.60% by weight of cement was added in cement mortar in order to observe its effect on fresh and hardened properties of the cement mortar. The results showed by addition of Nanofibrillated Cellulose lead to decrease in the fresh density and bleeding rate of cement mortar. The results also showed that by addition of Nanofibrillated Cellulose in the cement mortar leads to increase in the rate of capillary and moisture absorption in the mortar and decrease in the length of the cracks formed on the plastered surface.
