Effect of Corundum and Basalt Aggregates on the Ballistic Resistance of UHP-SFRC

Popis výsledku v původním jazyce

Ultra-high-performance steel-fibre-reinforced concrete is a technologically advanced composite with a high ability to absorb and dissipate mechanical energy. This work investigates the possi-bility of increasing ballistic resistance by adding different percentages of corundum and basalt aggregate to concrete. The most common type of ammunition, a 7.62 x 39 mm calibre with a full-metal jacket and a mild-steel core, was used to test all samples. The size of the damage and the mode of failure was determined using a 3D scanner operating on the principle of photogrammetry. The experimental campaign showed that the addition of basalt and, especially, corundum ag-gregate has a positive effect on ballistic resistance. In particular, the increase in compressive strength and the slight decrease in depth of penetration (DOP) was observed in the case of the usage of the corundum aggregate.
