Abstract:
A configuration (100), all components of which are man portable in some embodiments, for holding panels (10) to protect assets against external force and impacts from airborne projectiles. An open box-like stackable frame module (800) holds panels (10) along a side of the frame (800). Multiple frames (800) are connected to construct a protective barrier, such as a wall (1000). Frames (800) include provisions for connection in a vertical configuration (1000) so as to allow stacking of the frames (800) to increase the height of the barrier. A method of installing is also provided.
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.
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.

Abstract:
A configuration (600), all components of which are man portable, for holding inexpensive composite panels (100) that protect assets against external force and impacts from airborne projectiles. An open box-like stackable frame module (1400) holds thin panels (100) along a longitudinal axis of the frame (1300). Multiple frames (1400) are connected to construct a protective barrier, such as a wall (1500). The panels (100) may be formulated of a very high strength portland cement-based concrete with one side, both sides, or both sides and all edges, covered with elastic material, the combination of which significantly reduces penetration of projectiles. A panel (100) may be covered with specially formulated elastic material (103) comprising multiple layers, each layer of a different type or thickness of elastic material (103). The elastic material (103) may include reinforcing material such as fabric woven from available COTS high-strength fibers. The panels (100) may be fabricated using basic means available in rural locations. A method of installing is also provided.

Abstract:
A self-leveling cementitious mixture with excellent flow properties and which hardens with a controlled rate of strength development to an ultra-high compressive strength composite composition for use in making articles such as cementitious armor panel with ballistic and blast resistant properties including: a continuous 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, pozzolanic mineral filler, polycarboxylate based self-leveling agent and water. The cementitious mixture may include alkanolamine, such as thethanolamine, and acid or acid salt, such as tartaric acid. The cementitious composition may be reinforced with reinforcing fibers, e.g. glass fibers, in an amount of about 0.5 - 6.0 % by volume of the overall cementitious composition. The fibers are uniformly dispersed in the cementitious composition before it is cured to form a final cementitious armor panel.
