Paper Title
Resistance of Ultra High-Performance Concrete with Basalt Addition against Projectile Impact
Abstract
The aim of this paper is focused on the influence of the basalt as a coarse aggregate in ultra high-performance
concrete (UHPC) on its resistance against extreme load. The paper deals with a projectile impact resistance of ultra highperformance
steel-fibre-reinforced concrete (UHPFRC) in terms of depth of penetration and size of the crater. The samples
made of UHPFRC with different types and quantities of basalt were designed and produced, to be subjected to impact
loading in the form of projectile impact. Damaged surface of samples were scanned by means of a 3D scanner and the
damaged parts was evaluated. The main goal of the paper was to find the optimum content of basalt as a coarse aggregate in
the mixture in order to improve its resistance against projectile impact.
