Blast testing of ultra-high performance concrete fortifications using local materials
Abstract
This paper presents experimental results on blast testing of fortifications made from ultra high performance concrete (UHPC) and ordinary concrete (NC) by a non-contact explosion test with the TNT explosive. UHPC and NC samples used in the test were of the type of precast fortification of the real-scale and structure. TNT explosive was used in the test with a mass of 600 g per detonation. The explosive charge was centered on the top of fortifications, with the distance from the center of the explosion to the top of the fortification roof being 600 mm, 450 mm, and 300 mm, respectively. The test results, i.e., the strain of fortification roof ele-ments, the explosive load resistance, and the destruction level, were evaluated by comparing the UHPC and NC fortifications.
