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 for manufacturing a concrete product includes providing a metal-based cementing agent, and an acid-based cement reacting agent of the form H.sub.nXO.sub.m, where X is an element selected from group consisting of phosphorous, carbon, sulfur and boron, n and m are selected so that the cement reacting agent is an acid, and X will bond with the metal-based cementing agent to form a metal cement. The method further includes providing an aggregate defined by an exposed surface area having metallic aggregate linking elements thereon which can chemically bond with X in the presence of the acid-based cement reacting agent, and providing a hydroxide-supplying additive. The method includes combining together the metal-based cementing agent, the acid-based cement reacting agent, the aggregate and the hydroxide-supplying additive, and allowing the metal-based cementing agent and the acid-based cement reacting agent to react and bond with the aggregate to form the concrete product.
