Abstract: Concrete is the most widely used construction material in the world due to its ability to get cast in any form and shape. The strength and durability of concrete can be changed by appropriate changes in its ingredients like cementitious material, aggregate, water and by adding some special ingredients. However concrete has some deficiencies. The presence of micro crack in the mortar – aggregate interface is responsible for the inherent weakness of plain concrete. This weakness can be removed by inclusion of fibers in the mixture. Different types of fibers those used in traditional composite material can be introduced into the concrete mixture to increase its toughness or ability to resist crack growth. Such a concrete is called as fiber reinforced concrete. The newly developed fiber reinforced concrete named as engineered composite is 500 times more resistant to cracking and 40% lighter the traditional concrete.
The study has been carried out by using M30 grade concrete. The combination of steel fibers and HDPE fibers with an aspect ratio of 50 and water cement ratio of 0.45 has been used. The percentage of steel fiber is kept constant i.e. 0.5% and the percentage of HDPE fiber is varied from 0.5% to 2.0% by volume of concrete. The study has been concentrated on analysis of strength characteristics the compression, tensile, flexure, shear tests are planned.
