Experimental investigation on blast load resistance of reinforced concrete slabs retrofitted with epoxy resin impregnated glass fiber textiles

Blast mitigation of civil and transportation infrastructure is in focus due to the ever‐present volatile geopoliticalsituation. Structures are not designed to withstand blast load, and in areas of an imminent attack, their sensi-tive elements require blast retrofit. The retrofit technique selected follows three criteria: speed and ease ofapplication and relatively low price. Commercially available glassfibers, in the form of textiles and mats, wereapplied on RC slabs using epoxy resin. The test program consisted of two phases. Thefirst phase consisted oflaboratory four‐ point static bending tests of RC slabs to determine the feasibility and efficiency of devised retro- fit. The second phase consisted offield blast tests of RC slabs to study blast behavior and determine the appli-cability of devised retrofits. Applied retrofit has been proved useful in reducingflying debris and maximumdeflection in the tested range of explosion.
