- EPS foam blast attenuation in full-scale field test of reinforced concrete slabs Fausto Batista Mendonça Girum Solomon Urgessa Rita Lazzarini Dutra Rene Francisco Boschi Gonçalves Koshun Iha José Atilio Fritz Fidel Rocco Ingeniería non Blast test pressure reduction reflected pressure expanded polystyrene Predicting explosion parameters is an important step when planning for blast tests or the design of blast resistant buildings. This paper presents a comparison of recorded pressure that was reflected on the surface of reinforced concrete slabs with and without EPS (Expanded Polystyrene) foam retrofit measured from a detonation of 2.7 kg of non-confined plastic explosive. Two 50 MPa reinforced concrete slabs measuring 1.0x1.0x0.08 m, simply supported on two sides were tested. The explosive was suspended at a distance of 2.0 m from the upper surface of the slabs; one of the slabs had 5.0 cm thick foam on the top side. Eight piezoelectric pressure sensors were positioned at a distance of 2.0 m from the explosive. Results showed that the foam retrofit reduced the reflected pressure by approximately 57% when compared to the slab without EPS foam retrofit. 2020 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303265671001 https://www.redalyc.org/journal/3032/303265671001/ https://www.redalyc.org/journal/3032/303265671001/html/ https://www.redalyc.org/journal/3032/303265671001/303265671001.epub https://www.redalyc.org/journal/3032/303265671001/movil https://doi.org/10.4025/actascitechnol.v42i1.40020 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
