The application relates to road construction, in particular to a road surfacing composition which has favorable environmental as well as civil engineering and optical properties, to its use and to a method for maintaining, repairing and/or constructing an asphalt road surface. The invention provides a road surfacing composition comprising the components (i) 30-45vol% of olivine; (ii) 20-35vol% of supported photocatalyst which can convert NOx into nitrate; and (iii) 30-40vol% of light reflective road metal, based on the sum of the parts by volume of components (i), (ii) and (iii) in the composition, with the sum of the parts by volume being 100.
摘要:
Cement-based photocatalytic composition, which comprises: (a) at least one cement binder; (b) at least one photocatalyst; (c) at least one cellulose ether; (d) at least one fluidizing agent; (e) at least one first calcareous filler in the form of particles of which at least 95% by weight has a size not greater than 100 μm; (f) at least one second calcareous filler in the form of particles of which at least 95% by weight has a size not greater than 30 μm; (g) at least one silane supported on an inorganic support in the form of powder. Such composition can be employed as a water paint for obtaining wall coatings with very low thickness, in particular the outdoor applications, which ensure a high and stable photocatalytic effect over time even with relatively low quantities of photocatalyst, generally lower than 10% by weight, with optimal results in terms of uniformity of the coating and resistance of the same to weathering agents.
摘要:
The present disclosure relates to coating compositions, kits, and methods of applying the same, for use with fireproofing materials. The coating compositions are effective to control the drying rate and shrinkage of fireproofing materials. The coating compositions are also able to be applied to fireproofing materials shortly after these materials have been applied to a substrate.
摘要:
Plastomer-modified asphalt binders meeting MSCR specifications, asphalt paving materials with such asphalt binders, and methods for fabricating such asphalt binders are provided. The asphalt binder contains a base asphalt and a plastomer. If the plastomer has a drop point no greater than about 139° C., the asphalt binder further contains sulfur; sulfur-containing compounds, such as hydrocarbyl polysulfides and thiuram disulfides; phenolic resins; metal oxides; or a combination thereof. The asphalt binder is substantially free of elastomer.
摘要:
Compositions include an aerogel component and have low thermal conductivity. Methods for preparing slurries or composites include, for example combining the aerogel component with a surfactant, binder and other ingredients, such as, for instance, fibers. The compositions can be slurries that can be used in coating applications or self supporting rigid composites.
摘要:
Methods for adjusting the mechanical properties of cement systems include preparing a cement slurry containing water, an inorganic cement and at least two minerals. At least one of the minerals has a specific gravity higher than that of the cement at least one of the minerals has a specific gravity lower than that of the cement The slurry is allowed to harden and form a set cement. The concentrations of the cement and the minerals may be varied such that the slurry has a constant solid volume fraction and a constant slurry density.
摘要:
Die vorliegende Erfindung betrifft einen lösungsmittelfreien Mehr-Komponenten-Reaktionsharzmörtel auf Epoxidharzbasis mit mineralischen Füllstoffen und gegebenenfalls Pigmenten, welcher dadurch gekennzeichnet ist, dass dieser eine hohe Beständigkeit gegenüber wassergefährdenden Flüssigkeiten aufweist, derart, dass ein aus diesem Mörtel hergestellter Prüfkörper nach Aushärtung eine Eindringtiefe für Dieselkraftstoffe von weniger als 40 mm aufweist. Der Reaktionsharzmörtel eignet sich für die Instandsetzung von Betonbauteilen in LAU-Anlagen. Aus diesem Reaktionsharzmörtel wurden zylindrische Prüfkörper hergestellt und in eine Prüfflüssigkeit, beispielsweise Dieselkraftstoff für eine gewisse Zeitdauer eingelagert und danach wurde die Eindringtiefe der Prüfflüssigkeit bestimmt. Ein Längsschnitt durch einen solchen Prüfkörper 24 ist dargestellt, wobei durch Anlegen eines Maßstabs 25 verdeutlicht ist, wie weit die Prüfflüssigkeit in den Prüfkörper 24 eingedrungen ist. Die Linie der eingedrungenen Flüssigkeit ist mit 26 bezeichnet.
