A method of forming a lightweight concrete block and the resulting structure. Calcium sulfoaluminate (CSA) cement and specialized grout maybe added to an amount of water in a mixer. The CSA cement, specialized grout, and water may be blended to a smooth consistency. Lightweight aggregates (LWA) maybe added to form a mixture. The mixture may be poured into a mold, allowed the mixture to cure, and removed from the mold to form the lightweight concrete block. The lightweight concrete block may have a first side and a second side joined by a plurality of interposing walls, the interposing walls defining one or more inner cavities and one or more outer cavities. The lightweight concrete block may have features that allow for the insertion of fiberglass rebar to aide in stacking and filling to form a wall.

A method of forming a lightweight concrete comprising lightweight aggregates (LWA) made from recycled materials and the resulting composition. The lightweight concrete may be formed by adding calcium sulfoaluminate (CSA) cement and a specialized grout to an amount of water in a mixer, wherein a ratio of the water to the CSA cement is 1 quart to every 10 lbs of CSA cement. The CSA cement, specialized grout, and water may be blended to a smooth consistency. LWA may be added to the blended CSA cement, specialized grout, and water, wherein a ratio of the CSA cement to LWA is 60/40 by weight. The mixture of LWA, CSA cement, specialized grout, and water may be poured over a fiberglass rebar. The mixture may be allowed to cure and before being densified with a lithium densifier.

A pavement laying method and a polyurethane pavement coating are provided. The pavement laying method includes: providing a solid particle material; mixing a polyester polyol material and an isocyanate material into the solid particle material to form a mixed slurry; and laying the mixed slurry onto a pavement and solidifying the mixed slurry, so as to form a polyurethane pavement coating on the pavement. In addition, at least one of the polyester polyol material and the isocyanate material is derived from biomass resources.

A coating composition includes: an aqueous dispersion of self-crosslinkable core-shell particles, where the corm-shell particles include (1) a polymeric core at least partially encapsulated by (2) a polymeric shell having urethane linkages, keto and/or aldo functional groups, and hydrazide functional groups, where the polymeric core is covalently bonded to at least a portion of the polymeric shell, and a hydrophobic additive including a wax and/or a silicon-containing compound, where the hydrophobic additive is non-reactive with the polymeric core and the polymeric shell. A substrate coated with a coating formed from the coating composition and a method for improving stain resistance of a substrate are also disclosed.

An exterior sheathing cementitious panel which prevents water penetration and air leakage is provided. Methods for manufacturing exterior sheathing cementitious panels with a highly efficient integrated air/water barrier membrane are provided as well.

The present teachings contemplate a method for sealing comprising providing a substrate that includes a plurality of pores, locating a polymerizable composition onto a surface of the substrate, the polymerizable composition including a monofunctional, difunctional or multifunctional methylene malonate or a cyanoacrylate, and initiating polymerization of the composition, wherein polymerization is initiated by the use of an initiator or by the presence of a latent activating agent.

The present invention relates to a method for the manufacturing of a coated panel, in particular a wall, ceiling or flooring panel for applications in outdoor areas, as well as such a panel. The method comprises the following steps: providing a carrier plate of mineral wool and/or glass wool, comprising a front side and a rear side, applying a primer onto the front side of the carrier plate, thereafter applying a liquid first oligomer in an amount of 30 to 150 g/m.sup.2 onto the front side of the carrier plate; thereafter applying a liquid second oligomer, which differs from the first oligomer, in an amount of 30 to 180 g/m.sup.2 onto the wet surface of the before applied layer of the first oligomer.
