Abstract: A sprayable insulation composition curable at ambient conditions consisting essentially of:(a) a dry mix of 100-120 parts by volume of expanded perlite, 20-30 parts by volume of Portland cement, 0.5-2.0 parts by volume of hydrated lime and 0.1 part by volume of diatomite admixed with(b) an aqueous solution of 0.25-2 ounces per Imperial gallon of water-soluble foaming agent, at a level of 20-26 pounds of dry mix per one Imperial gallon of solution.

Abstract: A clip for holding an insulating and/or fireproofing panel to the surface of a structural member such as an I-beam or the like. The panel may be coated on one side thereof with a suitable adhesive and the clip will assist in supporting the panel in intimate contact with the surface of the structural member during the setting or hardening of the adhesive. In instances where the panel is left uncoated with an adhesive, the clip is strategically spaced along the length of the structural member to maintain the panel in close contact with the structural member.

Abstract: A self-hardening composition consists essentially of 3-5% by weight of an alkaline earth metal chloride, 0.5-1.5% by weight of calcium metasilicate, 0.5-1.5% by weight of sodium fluorosilicate, 30-40% by weight of sodium silicate, 0.02-0.04% by weight of aluminum silicate clay and water. Composites made therefrom can include expanded aggregate material and/or reinforcing fibers, as extenders, or to impart control over the open curing time to preset requirements.
