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.
