Light-weight, fire-resistant mineral foam includes an inorganic cementitious matrix and at least one metal hydrate that is a super hydrate substance, in which water is present with the substance in an amount of at least about ten moieties of water of hydration per formula unit of the substance. As a cured solid, that mineral foam, or another mineral foam composition including an inorganic cementitious matrix, can be provided as a structural member in part of an assembly that has at least one open web, thermally insulating support member at least partially embedded in the cured solid. Also, the cured mineral foam may be a solid foam in a form of a panel, panel block or tile, which may have a tongue provision and/or a groove provision.

A method to make an ultra-stable structural laminate of a cementitious material with a nano-molecular veneer and a foam component catalytically reacted into an expanded closed cell foam having a thickness from .sup.th inch to 8 inches, a density from 1.5 pounds/cubic foot to 3 pounds/cubic foot that inter-engages the cementitious material forming a matrix creating the ultra-stable structural laminate with fire resistance; a lateral nail pull strength from 44 pounds to 300 pounds of force; an insulation R value from 1 to 40; a resistance to seismic impact for earthquakes over 3.1 on the Richter Scale; a break point from 7 lbs/inch to 100 lbs/inch; and a resistance to wind shear equivalent to a 15 mph downburst.

An ultrastable cementitious material with nano-molecular veneer makes a cementitious material by blending 29 wt % to 40 wt % of a magnesium oxide dry powder containing 80 wt % to 98 wt % of magnesium oxide based on a final total weight of the cementitious material, with 14 wt % to 18 wt % of a magnesium chloride dissolved in water and reacting to form a liquid suspension, mixing from 2 to 10 minutes, adding a phosphorus-containing material, and allowing the liquid suspension to react into an amorphous phase cementitious material, wherein a portion of the amorphous phase cementitious material grows a plurality of crystals. The plurality of crystals are encapsulated by the amorphous phase cementitious material forming a nano-molecular veneer. A process to make the ultrastable cementitious material. A tile backer board incorporating the ultrastable cementitious material and a process for making the tile backer board.
