Abstract

There is sudden increase in blast phenomenon either due to terrorist attack or due to accidents. As a result, security and safety of structure becomes more important and considering blast load in design aspect of structure. One of the ways to increase the concrete strength is to increases the size of the member which will increase the stiffness of the structure and the uplift force below the foundation, but this not only increase the economy but also the factor of limited area will be restrain. This objective of this study is to find the mechanical strength of concrete which can withstand impact and blast loads. In this paper use of use of high-performance concrete is used along with bitumen fiber to give large deformation. Main focus was to increase the ductility of concrete and strong enough to resist blast impact loads without failure. Use of such concrete will considerably affect the economy of the structure by reducing the dimension of the members.
