    In the illustration of the column formwork above, the 'column clamps' are closer together at the bottom. Note that the column is braced with steel adjustable 'formwork props' and uses 20 mm 'through bolts' to further support the long side of the column. Some models of "permanent formwork" also can serve as extra reinforcement of the structure.

    en.wikipedia.org/wiki/Insulating_concrete_form

    The first expanded polystyrene ICF Wall forms were developed in the late 1960s with the expiration of the original patent and the advent of modern foam plastics by BASF. [citation needed] Canadian contractor Werner Gregori filed the first patent for a foam concrete form in 1966 with a block "measuring 16 inches high by 48 inches long with a tongue-and-groove interlock, metal ties, and a waffle ...

    en.wikipedia.org/wiki/Advanced_composite...

    Aluminium has a relatively high fracture toughness, allowing it to undergo large amounts of plastic deformation before failure. Composites, on the other hand, are less damage tolerant and undergo much less plastic deformation before failure. An airplane made entirely from aluminium can be repaired almost anywhere.

  6. Closed-cell PVC foamboard - Wikipedia

    en.wikipedia.org/wiki/Closed-cell_PVC_foamboard

    PVC foamboard is distinct from the extra-lightweight foamcore board, laminated of foam and card surfaces, used for indoor signage and modelling. Like PVC, closed-cell PVC foamboard is solid and has a very rigid structure. Where it differs is in its closed-cell foam structure, which makes it very light (as little as half the weight of solid PVC ...

    en.wikipedia.org/wiki/Sandwich-structured_composite

    Metal composite material (MCM) is a type of sandwich formed from two thin skins of metal bonded to a plastic core in a continuous process under controlled pressure, heat, and tension. [3] Recycled paper is also now being used over a closed-cell recycled kraft honeycomb core, creating a lightweight, strong, and fully repulpable composite board ...

    Tidy Sums. Like so many other things you don't need to buy, many cleaning products simply don't work well, do more harm than good, or can be skipped in favor of a much cheaper do-it-yourself solution.

    en.wikipedia.org/wiki/Foam_concrete

    Foam concrete, also known as Lightweight Cellular Concrete (LCC) and Low Density Cellular Concrete (LDCC), and by other names, is defined as a cement-based slurry, with a minimum of 20% (per volume) foam entrained into the plastic mortar. [1]
