Abstract
This research evaluates the performance of different protective solutions for reinforced concrete slabs subjected to blast loading. A series of full-scale blast tests were carried out on concrete slabs at scaled distances ranging from 0.20 to 0.83 m/kg1/3. For this purpose, 16 concrete slabs were tested; eight of them were unreinforced as ‘control specimens’, and the other eight were protected with five different protective solutions. After the tests, a damage assessment was conducted based on three different parameters. The results showed that there was no clear improvement in the concrete performance when the charge was located 0.5 m from the slab. Significant local damage that completely perforated the slab occurred. In the tests with the load placed 1 m from the slab, the reinforcements that were used significantly contributed to the retention of some fragments produced in these tests.
