Fiber Reinforced High Performance Concrete for Special Applications

Abstract

The paper refers to the experimental works being carried out within the research of special concrete precast elements of civilian infrastructure, which exhibit improved mechanical performance when exposed to the explosion.

The experimental work is aimed at designing the concrete mixtures for special applications such as trash bins and baggage lockers, in which several types of aggregate and reinforcement are used. The effects of aggregate types and sizes and types of reinforcement (oriented and randomly dispersed) are presented. The reinforcements used are various metallic and non-metallic nets and dispersed fibers. Mechanical and explosion tests were performed and the effect of different kinds of aggregate and reinforcement on explosion resistance and mechanical performance of the concrete samples were evaluated.

For lower explosion load levels the reinforced high performance concrete is a good and mainly inexpensive solution compared to recently applied other system.
