International Classification:

F41H 5/02

US Classification:

89 3602, 89901, 89903, 89920, 428911, 109 495

Abstract:

A cementitious armor panel assembly including cementitious armor panel with ballistic and blast resistant properties attached to a frame structure to produce a protective structure. The cementitious armor panels have a continuous phase resulting from the curing of an aqueous mixture of an inorganic cement binder, an inorganic mineral filler having a particle size of about 150-450 microns, a pozzolanic mineral filler, a polycarboxylate based superplasticizer self-leveling agent, and water. The mixture may also contain alkanolamine, and acid or acid salt. Prior to curing, the continuous phase is reinforced with fiber uniformly distributed in the continuous phase before it is cured to form the panel. The panel may be reinforced with a skin attached to at least one surface of the panel.

International Classification:

B32B 13/02

US Classification:

4282947, 428703

Abstract:

A cementitious panel with ballistic and blast resistant properties having a core layer of ultra-high compressive strength composite and at least one skin layer. The panels can also be used in walls, ceiling and flooring panels which require high compressive strength for resistance to earthquakes and surfaces resistant to surface abuse such as in prison and other institutions. The panel core layer has a continuous cementitious phase resulting from the curing of an aqueous mixture, in the absence of silica flour, of inorganic cement binder, inorganic mineral filler having a particle size of about 150-450 microns, a pozzolanic mineral filler, polycarboxylate based superplasticizer, alkanolamine and acid or alkali metal acid salt; and water. The mixture may be uniformly reinforced with fiber added before curing. The cementitious core layer is then reinforced with the skin, such as fiber reinforced polymer, attached to at least one panel surface.
