Impact Energy Assessment of Steel Fibre Reinforced Concrete

Abstract

A structural system is exposed to various types of loading conditions during its whole life span. Reinforced concrete and plane concrete are the most suitable materials used to construct any structural system owing to their inherent properties. Mechanical property such as high compressive strength makes it usable for static compressive loading, but these properties can't be used to anticipate the failure of concrete when exposed to extreme loadings. The study focuses on behaviour of normal concrete as well as performance of fibre reinforced concrete having various percentage of steel fibre, under static loading and impact loading. Initially, the performance of steel fibre reinforced concrete performance has been examined under traditional concrete tests such as compressive strength test and flexural strength test. In addition, the drop weight impact test has been carried out on standard specimens to assess the performance of normal as well as steel fibre reinforced concrete. The test results demonstrate that the impact resistance of fibre reinforced concrete is enormously improved by including steel fibres. It has also evident that with higher volume expansion of what, a more noteworthy improvement of impact resistance has been accomplished.
