The present invention relates to a composition for manufacturing methylene malonate cementitious hybrid systems. Particularly, the invention relates to a composition comprising at least one methylene malonate monomer (A), at least one methylene malonate polymer (B), at least one acidic stabilizer (C), and cement (D), to the preparation thereof, and to the use of the composition in construction, particularly as a surface protection material, a structural consolidation material or as a material used in underground constructions.

Provided is a silica aerogel blanket capable of preventing deterioration of heat insulating performance while reducing dust generation, and method for manufacturing the same. The method manufactures a low-dust silica aerogel blanket by separately adding a silica sol to prevent an opacifying agent from being exposed to the surface of the silica aerogel blanket.

A mineral wool insulating product which comprises a layer, notably a continuous layer, of mixed mineral wool fibres, the mixed mineral wool fibres comprising a binder, first mineral wool fibres and second mineral wool fibres, the first mineral wool fibres and the second mineral wool fibres have a difference of softening point.

A microfibrous shotcrete mixture which is used in mining applications, in highway, railway, subway tunnels, as excavation support element slope applications. The microfibrous shotcrete mixture provides a decreased amount of rebound. The objective of the present invention is to increase cohesion significantly and reduce the rebound amount in shotcrete up to four times by establishing a bridge between concrete particles by means of the special structure of the developed microfiber.

A mixture for a thermal insulating plaster, especially a mixture for a thermal insulating plaster that contains aqueous solution of silicate, which contains 78 to 90 volume percent of hollow glass microspheres, 5 to 17 volume percent of aqueous solution of potassium silicate, 0.1 volume percent of water-glass-binder stabilizer, 1.5 to 5 volume percent of styrene-acrylate dispersion, 0.4 to 3 volume percent of aqueous colloidal solution of silver, 0.2 to 2.4 volume percent of tensides as an aerating agent, and 0.5 to 7 volume percent of water.

The present invention relates to a coating composition comprising: 10 to 80 wt % of cerium oxide comprising a dopant based upon the total weight of the composition, wherein said dopant is selected from iron oxide, cobalt oxide, chromium oxide, lanthanum oxide, or mixtures thereof, and the atomic ratio of dopant metal to cerium is in the range 0.01:1 to 0.5:1; and 10 to 50 wt % of binder based upon the total weight of the composition.

Roofing substrates, including shingles, provide for protection of the structure it is covering as well as aesthetics. Shingles come in various types including asphalt, clay, and metal. The shingles may have a dry polymer modified cement mixture applied on top of current shingles or may be used to replace certain layers of, for example, asphalt shingles. The dry polymer modified cement may be applied before or after installation. The dry polymer modified cement may be colored to provide desired aesthetics and lower absorption of the sun's radiation (e.g., visible spectrum, infrared spectrum). The dry polymer modified cement may add minimum weight to the shingles while providing protection to the underlying substrate from environmental deterioration and weathering, thus increasing life of the shingle. The dry polymer modified cement mixture is prepared by mixing a dry polymer modified cement blend (ordinary Portland cement, aggregate and polymer powders) with water.

A mineral wool insulating product which comprises a layer, notably a continuous layer, of mixed mineral wool fibres, the mixed mineral wool fibres comprising a binder, first mineral wool fibres and second mineral wool fibres, the first mineral wool fibres and the second mineral wool fibres have a difference of softening point.

A spin caster for spraying a surfacing material upon an interior surface of a vessel includes a spin head configured to rotate about an axis, the spin head including an input port, and a supply line coupled to the input port and configured to convey a first material to the spin head and a second material to the spin head. The supply line comprises a first channel configured to convey the first material to the spin head and a second, different channel configured to convey the second material to the spin head.

A system for spraying granular pasty matrices onto buildings. A spray gun for a wet mortar which makes possible the easy, safe and efficient spraying of wet mortars including aggregates with a particle size D50 of between 1 and 15 millimeters. The system which it concerns which includes spray gun for wet mortar provided with gun body, with at least one injector emerging in contacting chamber, at least one spray nozzle for mortar, and at least one connection end piece mounted on inlet of body for flow of mortar. Flow of mortar within the guiding duct of body is monodirectional or multidirectional (angular deviation<30°. The position of injection head of the injector in chamber is adjustable. The mortar is constituted by a pasty matrix including aggregates, fillers and additives. The aggregates have a D50=1-15 mm and a form factor F≠1.
