The study is purely based on the tests carried out on jute mortar to observe the various changes and to know about its different properties. A result of 36 specimens (27cubes and 9 beams) with varying chemical modified ratios has been included in the experiment. A total 27 cube samples of 150mm x 150mm x 150mm size and 9 beams of 100mm x 100mm x 500mm were prepared to experiment. The result of specimens has been brought out in which compressive strength and flexural strength for each are evaluated for 7 and 28 days. The results were then compared with the conventional mortar specimens for each chemically modified jute at the respective ages. Results found shows that, the compressive strength increases by 48%, flexural strength increases by 55% and water absorption of chemically modified jute decreases by 50-60%. The investigation shows that, the chemically modified jute reinforced mortar is a very durable material and has higher strength than ordinary mortar and that too at very low cost when compared to new technological innovative materials.
