Abstract:
A prefabricated structural building panel is disclosed. The panel includes a first sheet having inner and outer planar surfaces. A plurality of structural ribs are disposed on the inner surface of the first sheet and are interconnected to form a geometric design having a plurality of chambers. The first sheet and the structural ribs are integrally formed as a single unit from a fiber and fly ash composite material.
Abstract:
In preferred form, the cement composite includes a mixture of a commercial grade fly ash having a high lime content and a dry flue-gas desulfurized fly ash. A prefabricated structural building panel is disclosed. The panel includes a first sheet having inner and outer planar surfaces. A plurality of structural ribs are disposed on the inner surface of the first sheet and are interconnected to form a geometric design having a plurality of chambers. The first sheet and the structural ribs are integrally formed as a single unit from a fiber and fly ash composite material.
Abstract:
A fiber-reinforced concrete used for molding or extruding a variety of building materials includes a mixture of cement, sand, water, liquid sodium silicate, plasticizer and hydrophobic fiber. The water, liquid sodium silicate and plasticizer are mixed together before adding the sand and cement to the mixture. The last component to be added to the mixture is the hydrophobic fiber.
Abstract:
A process of making a light weight, cementitious, three-dimensional structure such as a building panel which includes the steps of measuring a quantity of water, measuring about 425 kilograms of cement, and between approximately 40 to 60 grams of ferric chloride in 40 % solution by volume per approximately 278 liters of said water, mixing said quantity of water, said cement and said ferric chloride, measuring between approximately .620 kilograms and 1 347 kilograms of substantially pure powdered aluminum, between approximately .230 kilograms and .710 kilograms of Hexafluorosilicate, between approximately .560 and .680 kilograms of calcium formate, and between approximately 4 and 8 kilograms of fiber, per approximately 278 liters of said water, combining said mixture of said cement, said ferric chloride and said water with said powdered aluminum, said Hexaflurosilicate, said calcium formate and said fiber, mixing said combination, waiting until said mixed combination rises, and forming the lightweight, cementitious, three-dimensional structure.
Abstract:
The invention relates to a cement composition with synthetic or natural fibers and/or microfibers having a diameter smaller than 0.0508 mm (2 mils) in a proportion from 0.2 to 1.5 % by weight of the dry composition. The fibers along with other additives serve to achieve proper thixotropy, plasticity and preserve the dimensional structure and integral mechanical bonds of the obtained cement. The cement composition is excellent for modelling and is useful for constructing, machining, restoring or creating various forms with or without structural reinforcement and do so in the absence of fissures or cracks upon solidifying.
Abstract:
A process for modifying the slump of a concrete or mortar by the addition at different times of a water-soluble poly(alkylene oxide) and a (beta)-naphthalene sulphonate formaldehyde condensate, a plasticizer or superplasticizer which is selected from lignosulphonates, melamine sulphonate formaldehyde condensates, carboxylates and selected styrene-maleic anhydride copolymers. The poly(alkylene oxide) is preferably partially replaced by a (hydroxy)alkyl cellulose. The process is advantageously used in shotcreting.
Abstract:
The invention relates to a method for the continuous production of a low density mineral foam comprising the following steps: (i) preparing a cement slurry comprising: -cement; ultrafine particles of which the D50 is comprised from 10 to 600 nm; -a water reducing agent; a manganese salt; and water; (ii) adding to the cement slurry obtained after step (i) a gas-forming liquid comprising: a gas-forming agent; and a viscosity-modifying agent which is a polymer chosen among anionic bio- based polymer, amphiphilic bio-based polymer, alkali swellable acrylic polymer and mixture thereof; to obtain a foaming slurry; (iii) applying the foaming slurry obtained at step (ii) on a support; (iv) leaving the foaming slurry to expand on the support.
Abstract:
