Experimental Investigation on High Strength Concrete Using Polypropylene Fiber

K.L. Ravisankar, Dr.E.K. Mohanraj and B. Shyamala

Now-a-days the world is seeing the development of testing and troublesome structural designing structures. Concrete made with Portland cement having high compressive quality yet it has frail rigidity and it will in general be fragile. Likewise splits begin to create when cement is put and before it has appropriately solidified which may prompt debilitating of solid structures, break and disappointment and general absence of sturdiness. Thus this Project is aimed at reducing the aforementioned shortcomings of concrete to increase its applicability and performance. Addition of polypropylene fibers also leads to a reduction in shrinkage cracking. Polypropylene Fiber Strengthened Cement is a creating development material which can be depicted as a solid having high mechanical quality, Inflexibility and hardness. In this study various ratio of polypropylene fiber has used such as 0.25%, 0.50%, 0.75%, 1.00% and 1.25%. Each series consists of cubes, cylinders and prisms as per IS standard with M40 Grade and tests were carried out to find out the Compressive strength, Flexural strength, Split tensile strength and Deflection tests at various ages. The test result shown that the 1% addition of polypropylene fiber shows the optimized result.
