Abstract

Reducing spall damage is a major problem when designing blast-resistant concrete structures. This study was conducted to evaluate the influence of various material factors on the blast resistance of Fiber Reinforced Cementitious Composite (FRCC) slabs under contact detonation. The contact detonation tests were carried out on Polyvinyl Alcohol Fiber Reinforced Mortar (PVAFRM) slabs with four different shapes of PVA fibers and four different water-binder ratios (W/B) of the mortar matrix. Fly ash (type II) was used as admixture and the fluidity of the PVAFRM in its fresh state was varied using a superplasticizer and thickener. As a result, it was obtained that longer fiber is more effective to suppress spall if the fiber diameter is constant, and if the aspect ratio of fiber (lf/df) is constant, finer fibers are more effective to reduce spall. Moreover, the spall-reducing performance is reduced when the W/B value is too high or too low, and it is considered that there is an appropriate value of W/B that depends on the fiber shape.
