摘要:
Disclosed herein are corrosion-resistant composites. In particular, the composites can include a piezoelectric material embedded within a binding medium that can impede or inhibit the corrosive effects caused by salts and acids. Also disclosed herein are methods of making the composites and methods of protecting a concrete or concrete-related substrate from corrosion.

A method of forming a concrete wall having a substantially uniform exterior surface texture. The method includes the initial step of pouring concrete into a wall form. The concrete is poured from a first mixture and is allowed to cure. After the concrete is cured, the wall form is removed from the resultant concrete base structure. A roughened texture is then created on the base structure. A finishing mixture is then applied to the roughened texture. The finishing mixture may be created by separating the aggregate from a portion of the remaining first mixture. The finishing mixture creates a smooth texture on the exterior surfaces of the initially formed base structure.

A method for forming a uniform texture concrete wall using Shotcrete or other pneumatically projected concrete materials. The method generally includes forming an exterior face mixture from a concrete mixture wherein the large aggregates are removed such that when the face mixture is pneumatically applied to a base structure, the face mixture defines a uniform surface.

The invention relates to a building material (M2), which can be produced by combining 30 to 70% by weight of a cement or respectively hydraulic binder, 20 to 80% by weight of water and 0.05 to 15% by weight of a porous and/or pore-forming material; or by combining 10 to 80% by weight of a cement or respectively hydraulic binder, 10 to 80% by weight of a pulverulent and/or granular mineral filler, 20 to 80% by weight of water and 0.05 to 15% by weight of a porous and/or pore-forming material; and in each case by subsequent mixing of the combined components for 1 to 15 minutes. The invention furthermore relates to a building system element (1; 2) with a first section (11; 21) containing particularly compact solid particles distributed in a hardened cement matrix (M1) and fixed thereby, and with a second section (12; 22) containing pores distributed in a hardened cement matrix (M2). This second section (12; 22) can be composed of the building material (M2) according to the invention.
摘要:
A method for photocatalytic activation of at least one surface of a structural component having a porous mineral binder matrix, which is produced from an aqueous mixture of at least one mineral, inorganic binder, and generally at least one aggregate, additive and/or admixture, applies water to the surface of the structural component to be photocatalytically activated, until a film of water forms, immediately afterward applies dry fine-particle binder meal particles and fine-particle photocatalytically active particles in meal form to the water film, reacts the binder meal particles with water of the water film, and allows the water film disappear. The binder meal particles harden to form binder stone having a hydrate crystal matrix so that the photocatalytically active particles are bound into the binder stone, with surfaces remaining free, and the hydrate crystal matrix of the binder stone firmly combines with the surface matrix of the structural component.

A cementitious veneer and laminate composition is provided. The cementitious laminate composition includes a substrate, a primer layer applied to the substrate, the primer layer comprising a mixture of polyvinyl alcohol catalyst, Portland cement, and sand; and a cementitious veneer layer applied to the primer layer, the veneer layer comprising a mixture of magnesium sulfate, filler, magnesium oxide, gypsum cement, and polyvinyl alcohol catalyst. The polyvinyl alcohol catalyst comprises a mixture of polyvinyl alcohol fibers dissolved in water and mixed with butylene carbonate. The veneer layer is applied to the substrate and primer layer by means including spraying and manual spreading. The veneer layer can be ornamentally manipulated either before or after curing of the veneer layer. The veneer composition can be formed into laminated tiles or panels for use in building applications.
