Abstract:
Lightweight, fiber reinforced, cementitious panels possessing exceptional toughness for use as building components in applications such as roofing elements, siding elements, framing and sheathing elements, and substrate elements for installation of floor finishes in residential and other building construction types. The panels employ a continuous phase resulting from the curing of an aqueous mixture of inorganic binder, PVA fibers and lightweight filler. The inorganic binder may be, for example, hydraulic cement alone, or a combination of hydraulic cement and pozzolan/s, or a combination of hydraulic cement, alpha hemihydrate, active pozzolan and optionally lime. The PVA fibers reinforce the continuous phase and are randomly distributed throughout the composite. Typical panels of the invention have a density of 60 - 85 pcf.

Abstract:
The invention relates to a luminous composition including hydraulic cement, a polymer, limestone and micro-capsules of an alkaline earth metal aluminate encapsulated in a light-transmitting resin, light-transmitting glass or combination thereof. The invention is also directed to a method of making a luminous composition. The method includes cooling an alkaline earth metal aluminate encapsulated in a light-transmitting resin, light-transmitting glass or combination thereof to a temperature of about -250 F to about -350 F and rendering the encapsulated aluminate into a powder comprising micro-capsules of the alkaline earth metal aluminate encapsulated in the light-transmitting resin, light-transmitting glass or combination thereof, wherein the micro-capsules range in size from about 0.7 µm to about 200 µm. The method then includes combining the aluminate powder with hydraulic cement, a polymer and limestone.
Abstract:
Noncorroding reinforcing steel (16), and steel reinforced concrete (74), which has an adherent bond with hydrated concrete formed by a thermally sprayed hydraulically reactive layer (76) of a material such as blast furnace slag on the steel surface.
Abstract:
A method of treating a contaminated material comprising forming a low-permeability barrier (20) over the contaminated material (21) thereby creating a substantially hydraulically closed system and treating the material beneath the barrier by at least one of delivering a substance to treat the contamination and removing flowable material from beneath the barrier (20).

Abstract:
The invention relates to a granulated material, characterised in that it consists essentially of a core made up of fibres of paper and/or paperboard and/or card, or a core made up of clay substances and fibres of paper and/or paperboard and/or card and an outer layer consisting of clay substances. The invention also relates to a material containing clay substances and fibres of paper and/or paperboard and/or card, the proportion of clay substances being between 2 and 98 % vol. and the proportion of fibres of paper and/or paperboard and/or card being between 98 and 2 % vol.
Abstract:
A method of producing a non-combustible composite material structure, which comprises the steps of forming a non-combustible liquid continuous phase matrix by adding and mixing metal oxide powder and liquid soluble silicate, preparing a dispersed phase comprising non-combustible fibers or particles, forming an intermediate structure of a composite material by wetting the dispersed phase by the liquid continuous phase, and drying the intermediate structure to cure the continuous phase and obtaining a solidified non-combustible composite material structure. A preferred method provides a composite material laminate structure of a plurality of layers containing continuous glass fibers oriented in two directions. This composite material structure is available in various forms such as a tube structure, a sheet member, a foamed heat insulating material and a paint coating material.
