“…For decades, previous studies have utilized fiber-reinforced composites at both material and structural levels to improve the blast and impact resistance of cement-based composite materials (Yamaguchi et al 2011;Silva and Lu 2007;Ohkubo et al 2008;Ha et al 2011;Wu et al 2009;Mosalam and Mosallam 2001;Razaqpur et al 2007;Xie et al 2014;Ohtsu et al 2007;Lan et al 2005;Soe et al 2013;Nam et al 2010;Kim et al 2015;Li et al 2016;Coughlin et al 2010;Yoo et al 2015;Kim et al 2015;Yoo and Yoon 2016;Nam et al 2016). Yamaguchi et al (2011) reported that polyethylene fiber-reinforced concrete has superior blast resistance under contact explosions as compared with normal RC.…”

This study investigates the blast resistance of fiber-reinforced cementitious composite (FRCC) panels, with fiber volume fractions of 2%, subjected to contact explosions using an emulsion explosive. A number of FRCC panels with five different fiber mixtures (i.e., micro polyvinyl alcohol fiber, micro polyethylene fiber, macro hooked-end steel fiber, micro polyvinyl alcohol fiber with macro hooked-end steel fiber, and micro polyethylene fiber with macro hooked-end steel fiber) were fabricated and tested. In addition, the blast resistance of plain panels (i.e., non-fiber-reinforced high strength concrete, and non-fiberreinforced cementitious composites) were examined for comparison with those of the FRCC panels. The resistance of the panels to spall failure improved with the addition of micro synthetic fibers and/or macro hooked-end steel fibers as compared to those of the plain panels. The fracture energy of the FRCC panels was significantly higher than that of the plain panels, which reduced the local damage experienced by the FRCCs. The cracks on the back side of the micro synthetic fiber-reinforced panel due to contact explosions were greatly controlled compared to the macro hooked-end steel fiber-reinforced panel. However, the blast resistance of the macro hooked-end steel fiber-reinforced panel was improved by hybrid with micro synthetic fibers.

“…Morishita et al (2000Morishita et al ( , 2004 and Tanaka et al (2003) have studied the influences of concrete strength, bar arrangement, and amount of explosives on the damage to normal RC slabs, and proposed a useful method for estimating the size of the damage to normal RC slabs subjected to contact detonation. Furthermore, the following techniques have been proposed for improving the blast resistance of RC slabs: one is strengthening with fiber reinforced polymer (FRP) composites (Muszynski et al 2003;Buchan et al 2007;Razaqpur et al 2007;Silva et al 2007) or steel plates (Lan et al 2005) on the blasted and/or rear surface of the RC slab; the other technique is employing a fiber reinforced concrete as the slab material (Sun et al 1999;Banthia et al 2004;Lan et al 2005;Ngo et al 2007;Zhou et al 2008;Coughlin et al 2010).…”

When designing blast-resistant reinforced concrete (RC) structures, reducing spall damage due to reflected tensile stress waves is a major problem. To investigate the applicability of polyethylene fiber reinforced concrete (PEFRC) for use in blast-resistant RC structures, experimental investigations were conducted to evaluate the damage to PEFRC slabs subjected to contact detonation. As a result, it was shown that PEFRC was effective in reducing the spall damage due to contact detonation as compared with normal RC. Moreover, an equation for estimating damage depth to the PEFRC slab subjected to contact detonation was derived based on the test results.

“…Until now, a number of experimental and numerical studies have been conducted regarding the evaluation of damage to normal RC slabs subjected to contact detonation (Hader 1985;McVay 1988;Kraus et al 1994;Nash et al 1995;Morishita et al 2000Morishita et al , 2004Tanaka et al 2003;Katayama et al 2007). Furthermore, the following techniques have been proposed for improving the blast resistance of RC slabs: one is strengthening with fiber reinforced polymer (FRP) composites (Muszynski et al 2003;Buchan et al 2007;Razaqpur et al 2007;Silva et al 2007) or steel plates (Lan et al 2005) on the back surface of the RC slab; the other technique is employing a fiber reinforced concrete as a slab material (Sun et al 1999;Banthia et al 2004;Lan et al 2005;Ngo et al 2007;Zhou et al 2008;Coughlin et al 2010). The authors also conducted the contact detonation tests on polyethylene fiber reinforced concrete (PEFRC) slabs and showed that the PEFRC was more effective in reducing spall damage due to contact detonation as compared with normal concrete (Yamaguchi et al 2008a(Yamaguchi et al , 2011.…”

When designing blast-resistant reinforced concrete (RC) structures, reducing spall damage due to reflected tensile stress waves is a major problem. Furthermore, for rapid construction of the blast-resistant structures against sudden terrorist bomb attacks, it is necessary to build it with precast concrete walls and reduce the weight of the precast elements by reducing their size for ease of transportation and construction. In this study, to propose an idea for rapid construction and better blast resistance of blast-resistant RC structures, double-layered RC slabs composed of precast thin plates, 50 mm thick, were fabricated and utilized for contact detonation tests. The tests were conducted under a condition that the amount of explosives and the dimensions of specimen were constant respectively, and two types of concrete, normal concrete and polyethylene fiber reinforced concrete (PEFRC), were employed as the slab materials. Our results showed that creating an air cavity between the two layers of PEFRC slab was effective in reducing spall damage, while the air space had no advantage in normal RC, under a condition that the thickness of the air space was fixed at 15 mm. Furthermore, the above difference between PEFRC and normal RC slabs was discussed, based on the numerical result on the fracture process of the air-sandwiched normal RC slab.
