  2. Precast concrete - Wikipedia

    en.wikipedia.org/wiki/Precast_concrete

    Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and maneuvered into place; examples include precast beams, and wall panels, floors, roofs, and piles.

  3. Prestressed concrete - Wikipedia

    en.wikipedia.org/wiki/Prestressed_concrete

    Prestressed concrete is a form of concrete used in construction. It is substantially prestressed during production, in a manner that strengthens it against tensile forces which will exist when in service. [1] [2]: 3–5 [3] It was patented by Eugène Freyssinet in 1928. [4]

  4. Lintel - Wikipedia

    en.wikipedia.org/wiki/Lintel

    Modern-day lintels may be made using prestressed concrete and are also referred to as beams in beam-and-block slabs or as ribs in rib-and-block slabs. These prestressed concrete lintels and blocks can serve as components that are packed together and propped to form a suspended-floor concrete slab. An arch functions as a curved lintel. [1] [2]

  5. Beam and block - Wikipedia

    en.wikipedia.org/wiki/Beam_and_block

    Beam and block is a construction method to support flooring, especially for ground floors as well as multi story buildings. [1] It is made of cast concrete, one piece of which is a prestressed concrete beam, which can be an inverted T-shaped beam, or lintel, the other piece being a simple rectangular block. [1]

  6. Autoclaved aerated concrete - Wikipedia

    en.wikipedia.org/wiki/Autoclaved_aerated_concrete

    Reinforced autoclaved aerated concrete (RAAC) is a reinforced version of autoclaved aerated concrete, commonly used in roofing and wall construction. The first structural reinforced roof and floor panels were manufactured in Sweden. Soon after, the first autoclaved aerated concrete block plant started there in 1929.

    A component that securely connects separate segments of post tensioning ducting, commonly used when joining precast concrete segments in a prestressed structure. dummy strand A short length of prestressing strand pre-installed into ducting during concreting to maintain duct integrity. Occasionally used at some jointing arrangements.

  8. Jack arch - Wikipedia

    en.wikipedia.org/wiki/Jack_arch

    A jack arch is a structural element in masonry construction that provides support at openings in the masonry. Alternate names are lintel arch, [1] flat arch and straight arch. Unlike regular arches, jack arches are not curved in form. Instead, they are flat in profile and are used under the same circumstances as lintels.

  9. Precast concrete lifting anchor system - Wikipedia

    en.wikipedia.org/wiki/Precast_concrete_lifting...

    The anchor selection, together with additional reinforcement, and rigging arrangements is influenced by: - The dead weight of the element - The number of anchors in the element and the configuration of the anchor - Capacity of the anchor at the specific concrete compressive strengths at time of lift - The dynamic loads applied during lifting ...
