Experimental investigation of blast impact on concrete using steel fibers

Civil Engineering

The world has seen many divesting blasts during the last decade which killed many people and demolished many buildings. With the increased number of blasts the interest of research on blast resistant building materials and building techniques has increased in a rapid place. It is better go for protective measures during design and construction to withstand the worst that could happen. In this project thesis we are going to replace fly ash 30% with admixture and steel fibre 0%, 0.5%,1%,1.5%and 2% and the curing days from 7,14 & 28 days .Test were casting on cubes , cylinder and beam to conduct the compressive , split tensile and Flexural test of concrete for M30 concrete using IS method. Therefore the need of new materials and technologies is much essential for building blast resistant structures. It is found that steel fibers reinforced concrete has shown some satisfactory results during the blast, but still is not good enough to with stand completely for a blast. An experimental study on slab samples of M30 concrete with 10mm rod steel reinforcement with and without steel fiber reinforcement is tested and with different magnitude of energy release by blast.
