Blast responses of polyurea-coated concrete arches
The effects of polyurea coating on anti-explosion performances of reinforced concrete arches were studied through explosion experiments. Three coating schemes were proposed and investigated, including intrados coating, enclosed coating and fiber-grid/polyurea hybrid coating. The arches exhibit cracking, spalling and crashing failure modes in succession accompanying with reducing the scaled distance. The damage degree of the exploded arch is evaluated quantitatively by the residual load carrying capacity under quasi-static mid-span concentrated loading experiments. It is revealed that polyurea coatings have excellent anti-spalling ability than carbon fiber-reinforced polymer (CFRP) strengthening method and greatly increase the blast-resistance of the concrete arch and enclosed polyurea coating is the most efficient.
