Decoupage or découpage ( / ˌdeɪkuːˈpɑːʒ /; [ 1] French: [dekupaʒ]) is the art of decorating an object by gluing colored paper cutouts onto it in combination with special paint effects, gold leaf, and other decorative elements. Commonly, an object like a small box or an item of furniture is covered by cutouts from magazines or from ...
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [ 1] The IUPAC name for an epoxide group is an oxirane .
Decalcomania (from French: décalcomanie) is a decorative technique by which engravings and prints may be transferred to pottery or other materials. A shortened version of the term is used for a mass-produced commodity art transfer or product label, known as a "decal". Decalcomania is adapted from French décalcomanie, equivalent to décalquer ...
Collage. Collage ( / kəˈlɑːʒ /, from the French: coller, "to glue" or "to stick together"; [ 1]) is a technique of art creation, primarily used in the visual arts, but in music too, by which art results from an assemblage of different forms, thus creating a new whole. (Compare with pastiche, which is a "pasting" together.)
This is important for long-term use of some materials, such as composites and sealants. [13] By dissolving minerals in enamel, etchants remove the outer 10 micrometers on the enamel surface and make a porous layer 5–50 micrometers deep. [42] This roughens the enamel microscopically and results in a greater surface area on which to bond.
Roman concrete, also called opus caementicium, was used in construction in ancient Rome. Like its modern equivalent, Roman concrete was based on a hydraulic-setting cement added to an aggregate. Many buildings and structures still standing today, such as bridges, reservoirs and aqueducts, were built with this material, which attests to both its ...
Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures to a solid over time. Concrete is the second-most-used substance in the world after water, [ 1] and is the most widely used building material. [ 2] Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium combined.
The composition of PM generated from cutting or mixing concrete made with Portland Cement would be different from those generated from cutting or mixing concrete made with different types of slag (e.g. GGBFS, EAF slag [164]), fly ash or even EAF dust (EAFD), [165] while EFAD, slag and fly ash are likely to be more toxic as they contain heavy ...
