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 ...
Roman concrete, like any concrete, consists of an aggregate and hydraulic mortar, a binder mixed with water that hardens over time. The composition of the aggregate varied, and included pieces of rock, ceramic tile, lime clasts, and brick rubble from the remains of previously demolished buildings. In Rome, readily available tuff was often used ...
In the United Kingdom, fly ash has been used for over fifty years to make concrete building blocks. They are widely used for the inner skin of cavity walls. They are naturally more thermally insulating than blocks made with other aggregates. [39] Ash bricks have been used in house construction in Windhoek, Namibia, since the 1970s. There is ...
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.

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.)
Papercrete. Papercrete is a building material that consists of re-pulped paper fiber combined with Portland cement or clay, as well as other soils. First patented in 1928 by Eric Patterson and Mike McCain [ 1] (who originally named it "padobe" and "fibrous cement"), it was revived during the 1980s.
Foam concrete is a versatile building material with a simple production method that is relatively inexpensive compared to autoclave aerated concrete. [1] Foam concrete compounds utilising fly ash in the slurry mix is cheaper still, and has less environmental impact. Foam concrete is produced in a variety of densities from 200 kg/m 3 to 1,600 kg ...
