Abstract:

In this experimental work to reduce the usage of cement, supplementary cementing materials like fly ash and GGBS (Ground Granulated Blast furnace Slag) are used as cement replacing materials. The investigations are carried for the compressive test, flexural strength test on the concrete specimens. Usage of natural fibers in a relatively brittle cement matrix has attained significant toughness and strength of the composite. When comparing the 28th day cube compressive strength test results it is noticed that the Jute Fibre Reinforced Cement Concrete mix (JFRCC) with 30% GGBS has maximum compressive strength of 46.32 N/mm2 which is 8.86% higher than normal concrete and 15.8% higher than JFRCC with 30 % Fly ash. In case of JFRCC with 30 % GGBS has the maximum deflection of 20.46 mm under the moment of 2.475 kNm which is 9.09% higher than the normal RCC beam.

Keywords:
