  2. Cellular floor raceways - Wikipedia

    en.wikipedia.org/wiki/Cellular_floor_raceways

    Cellular floor raceways. Cellular floor raceways are electrical wiring ducts or cells made from steel floor deck that serve as structural formwork for placement of concrete floor slabs and also as wire and cable raceways within the concrete floor slab. These raceway systems are generally used to create floor slabs on multi-story steel-framed ...

  3. Fiber-reinforced concrete - Wikipedia

    en.wikipedia.org/wiki/Fiber-reinforced_concrete

    Fiber-reinforced concrete or fibre-reinforced concrete ( FRC) is concrete containing fibrous material which increases its structural integrity. It contains short discrete fibers that are uniformly distributed and randomly oriented. Fibers include steel fibers, glass fibers, synthetic fibers and natural fibers [ 1] – each of which lend varying ...

  4. Reinforced concrete - Wikipedia

    en.wikipedia.org/wiki/Reinforced_concrete

    The plate assemblies are fabricated off site, and welded together on-site to form steel walls connected by stringers. The walls become the form into which concrete is poured. Steel plate construction speeds reinforced concrete construction by cutting out the time-consuming on-site manual steps of tying rebar and building forms.

  5. Concrete - Wikipedia

    en.wikipedia.org/wiki/Concrete

    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.

  6. History of fluid mechanics - Wikipedia

    en.wikipedia.org/wiki/History_of_fluid_mechanics

    The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history. The field has undergone a continuous evolution, driven by human dependence on water, meteorological conditions and internal ...

  7. Epoxy - Wikipedia

    en.wikipedia.org/wiki/Epoxy

    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 .

  8. Hollow-core slab - Wikipedia

    en.wikipedia.org/wiki/Hollow-core_slab

    The slabs are typically 120 cm wide with standard thicknesses normally between 15 cm and 50 cm. Reinforcing steel wire rope provides bending resistance. Slabs in prestressed concrete are usually produced in lengths of up to 200 meters. The process involves extruding wet concrete along with the prestressed steel wire rope from a moving mold. The ...

  9. Composite construction - Wikipedia

    en.wikipedia.org/wiki/Composite_construction

    In structural engineering, composite construction exists when two different materials are bound together so strongly that they act together as a single unit from a structural point of view. When this occurs, it is called composite action. One common example involves steel beams supporting concrete floor slabs. [1]
