Investigation of Expanded Foam in Control and Reduction of Explosive Blast

Expanding foam for controlling and reducing explosive blast have been used to reduce the harmful effect of shock wave when neutralization of explosives in public area and chemical warfare is to be performed. Recently, usage of expanding foam to reduce harmful effect of shock wave in the mine and petroleum site are developed. The reduction of blast noise by foam has also been studied. The major parts of this type of foam are aqueous. Some solid foams based on polymer have also been proposed, absorbing the shock wave and distributing the weight of persons or vehicles on the surface of sheet plat foamed to afford the possibility of safe passage through the land mine. In this contribution, the application and formulation of different type of foams to control and reduce the explosive blast are investigated.
