Abstract : In recent past use of natural fiber as reinforcing agent in construction materials is drawing attention of the researchers on the virtue of improving mechanical strength of the concrete. Although the natural fiber has enough potential to act as reinforcing agent in concrete products, its compatibility in cementitious matrix is real concern. This paper evaluates the compatibility of jute fiber in cement matrix by setting time measurements as well as demonstrates the feasibility of jute fiber as a reinforcing agent in commercial concrete products viz. paver blocks. The paver blocks containing 1wt% (w.r.t. weight of cement) chemically modified jute fiber show 69% and 54% higher compressive and flexural strengths, respectively than that of the reference one. The retention of tensile strength values of the chemically modified jute fibers, in cement matrix after 90 days curing, was found to be as high as 97.7 %, which signifies the durability of the fibers within the cement matrix.
