The present disclosure describes architectural blocks configured to give the appearance of real cut stone. A fresh plaster composition may be applied to one or more surfaces of a block, such as a concrete masonry unit (CMU) to form an architectural block having the appearance of cut stone. The fresh plaster composition includes a cementitious component, such as white Portland cement, water, a limestone aggregate component, and optionally an adhesive component. The limestone aggregate component includes a fine sand portion and a coarse sand portion that effectively enable the appearance of cut stone after finishing of the hardened or curted plaster surface via sanding and/or polishing.

The present invention relates generally to silicate-based coatings and to methods to make and apply same. In one embodiment, the silicate-coatings of the present invention are formed from a two part mixture of phosphate-based component and a glass-based component. In another embodiment, the silicate-based coatings of the present invention are free from any organic materials.

The present invention relates to nanoparticles and their use to form nanocomposite material, in particular bionanocomposite material, specifically wherein the nanoparticles are formed using plant virus attached to a scaffold of cellulosic material and/or cellulose derived materials, in particular wherein said cellulosic material further comprises plant cell components, for example hemicellulose, pectin, protein or combinations thereof.

A two-component hybrid coating system which contains both an organic film forming polyacrylate polymer and particles capable of forming a geopolymer is provided. When the two reactive components are combined, a hybrid coating composition is provided containing a film forming organic polyacrylate polymer component and a geopolymer component.

A concrete and asphalt repair coating formulation includes a cement component and an aggregate component. The cement component includes a calcium sulfoaluminate cement and a Portland cement. The aggregate component includes coarse aggregates between 125-500 microns in diameter and fine aggregates between 5-62.5 microns in diameter.

Disclosed are an organic binder-based coating; a composite gypsum board containing face and back cover sheets, an outside surface of the back cover sheet bearing the coating; and a method of preparing composite board where the back cover sheet contains the coating on its outer surface. The coating is formed from a composition comprising an alkaline silicate, a solid filler, and optionally, a borate. An enhancing layer can also be applied to the back cover sheet.

A roofing material is provided that comprises a coating composition including a filler and a bituminous composition comprising at least one bitumen base, at least one compound of general Formula (I): Ar1-R.sub.1—Ar.sub.2 (I), and at least one compound of general formula (II): R.sub.2—(NH).sub.nCONH—X—(NHCO).sub.p(NH).sub.n—R′.sub.2 (II). The invention also concerns a process for the preparation of a roofing material comprising the coating composition.

The present invention relates to a water-based coating composition, the preparation and use of the composition, a two-component coating system comprising the composition and use thereof, and an article obtained by coating with the composition or the two-component coating system. The water-based coating composition comprises a water-based UV resin; a silane-treated nanosized silicon oxide compound; and a photoinitiator; wherein per kilogram of the solid constituent of the water-based UV resin contains not less than 3 mol of ethylenically unsaturated groups, and wherein the weight ratio of the solid constituent of the nanosized silicon oxide compound to the solid constituent of the water-based UV resin is 11:20 to 73:100. The coating layer formed by the water-based coating composition of the present invention has high hardness and good adhesion, and is particularly suitable for electronic, electrical and communication equipment in the 5G field.

An inverted roof and a method of installing the inverted roof, and in particular to an inverted roof including cellular glass insulation material having a protective alkali silicate coating on the upper surface of the cellular glass insulation material.

The invention relates to a potting paste composition for honeycomb reinforcement having improved fire retardancy characteristics. The potting paste composition comprises (a) a curable polymer; (b) a curing agent for the curable polymer; (c) a fire retardant comprising an ammonium polyphosphate in combination with an ingredient selected from the group consisting of metal hydroxides, expandable graphites, liquid phosphate esters, phosphorous organic compounds or salts thereof, and zeolites; and(d) a filler selected from the group consisting of polymeric microspheres, hollow glass microspheres, and thixotropic fillers; wherein the potting paste has an uncured density determined by the method according to EN ISO 1183 of not more than 0.7100 g/cm.sup.3, preferably of at most 0.680 g/cm.sup.3, more preferably of at most 0.673 g/cm.sup.3, still more preferably of at most 0.660 g/cm.sup.3, even more preferably of at most 0.658 g/cm.sup.3, yet more preferably of at most 0.653 g/cm.sup.3 and in particular of at most 0.620 g/cm.sup.3; and wherein the total content of the fire retardant is at least 5.0 wt.-%, preferably at least 10 wt.-%, more preferably at least 15 wt.-%, relative to the total weight of the potting paste composition.
