The present invention provides a liquid composition of quicklime particles within an alkylene glycol-based paste or slurry environment, which allows for pumpability and meterability of a liquid composition into cementitious materials such as concrete and mortar. Treated quicklime particles of the present invention manifest an unexpected and surprising hydration induction postponement behavior, as demonstrated through calorimetric testing.

Disclosed are a polymer cement-granite composite tomb box and a preparation method thereof. The tomb box has a layered structure or an upper-lower composite structure, where the layered structure is composed of one or two layers of granite slabs and one layer of the polymer cement, and an upper portion of the upper-lower composite structure is made of granite slabs, and an lower portion of the upper-lower composite structure is made of the polymer cement or a combination of the polymer cement and the granite slabs.

Disclosed are composite building boards and associated manufacturing methods. The composite boards may include, for example, one or more slurry layers with embedded fibrous mats. An exterior plastic coating is mechanically adhered to the underlying slurry layer. The plastic layer chemically bonds and cross-links with polymer additives within the slurry layer. The result is an integrated polymer matrix with greatly improved durability and surface strength.

Pavement aging can be reduced by applying to an asphalt-containing pavement a topcoat layer or a surface treatment containing asphalt binder emulsion with sterols.

A board consisting at least of a substrate formed at least of a gypsum-based and/or cement-based basic material layer. The board is provided with a chamfer extending through the basic material layer.

The present application relates to a concrete pre-mix composition comprising a cementitious material and a plurality of conductive carbon microfibers mixed with said cementitious material, where said conductive carbon microfibers are present in the concrete pre-mix composition in an amount such that, when said concrete pre-mix composition is hydrated to form concrete and cured, the conductive carbon microfibers are dispersed in the cured concrete in an amount of 0.75% to 2.00% of total mass of the concrete. The present application further relates to a concrete composition, a method of producing an electrically conductive concrete composition, an electrically conductive cured concrete form, and a system for heating pavement.

The invention comprises a concrete form. The concrete form comprises a first panel having a first primary surface for contacting plastic concrete and a second primary surface opposite the first surface, wherein the first panel is made from a rigid plastic sheet or a metal sheet; and a second panel spaced from the second primary surface of the first panel, wherein the second panel is made from a rigid plastic sheet or a metal sheet. The concrete form also comprises a layer of insulating material disposed between the first panel and the second panel. A method of using the concrete form is also disclosed.

The present invention relates to the use of carbon dioxide gas to cure concrete media by applying a pressure differential created through a partial replacement of the original ambient volume of air present in a curing enclosure with pure CO2 gas.

A decorative coatings method, system, device, and composition, wherein the initial part may be the blending of several materials to create the face coat. The next step may be the application of this face coat into a mold. Then the backfilling of this mold with another blended material that is not usually associated with the face coat. The method ensures the adhesion of the backfill to the face coat. The specific mixtures allow the materials to bond and form a solid product when removed from the mold.

A method for manufacturing a layered tile comprising a mutually connected ceramic tile and a concrete body, the method comprising the steps of applying an organic primer to a first surface of the ceramic tile, optionally positioning the ceramic tile in a mold, exposing the first surface, applying a concrete mixture on top of the tile's first surface, pre-hardening the concrete mixture for obtaining a green product, removing the product from the mold, and fully hardening the concrete for obtaining the layered tile.
