Abstract


Objectives: To evaluate the suitability of short coconut and PP fiber as a reinforcing agent in cement concrete. Mixing and casting of untreated coconut and PP fiber in RCC check the mechanical properties of HFRC. The experimental background is cited in the literature. Methods/Statistical Analysis: From the basic tested data a mix design for M20 grade concrete at a weight of cement fraction is 1%.For this work 12nos of cube (150 mm * 150 mm * 150 mm) and 12nos of beam (700mm *150 mm*150 mm) were casted by using different fiber proportion of polypropylene fiber & coconut fiber in the laboratory; along with one set of control sample were examined and compared with the HFRC. Findings: All the cube specimens were tested by UTM and beam specimens were tested in UTM by using two points loading as per IS 516-1959. The test result shows that the weight fraction of 1% with Polypropylene 0.75 – coconut coir 0.25 combination specimens improves compressive strength and flexural strength as compared with control specimen. Applications/Improvements: The use of hybrid fiber reinforced concrete in non-structural components like Walls & Surfaces of Septic Tank, Water Storage Tanks and Dams, Sports Grounds, Industrial, Residential Floors & Warehouses etc. The major contribution of fibers in crack resistance and crack control, improve ductility of concrete.
