  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. Retaining wall - Wikipedia

    en.wikipedia.org/wiki/Retaining_wall

    A retaining wall is designed to hold in place a mass of earth or the like, such as the edge of a terrace or excavation. The structure is constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil. [1]

    en.wikipedia.org/wiki/Mechanically_stabilized_earth

    A diagram of a mechanically stabilized earth wall as it would be modeled in a finite element analysis. Mechanically stabilized earth (MSE or reinforced soil) is soil constructed with artificial reinforcing. It can be used for retaining walls, bridge abutments, seawalls, and dikes. [1][2] Although the basic principles of MSE have been used ...

    en.wikipedia.org/wiki/Double_tee

    The Precast/Prestressed Concrete Institute (PCI) published the double tee load capacity calculation (load tables) for the first time in the PCI Design Handbook in 1971. The load tables use the code to identify double tee span type by using the width in feet, followed by "DT", followed by depth in inches, for example, 4DT14 is for 4-foot (1.2 m ...

  6. Bison industrialised building system - Wikipedia

    en.wikipedia.org/wiki/Bison_industrialised...

    Bison Manufacturing was founded in 1919 to build military pill-boxes. The Bison wall-frame construction system was a construction method used in tower block construction. It was launched in 1963 by Concrete Ltd who set up factories across the UK to pre-fabricate the parts it. It was not a frame structure as such, instead precast concrete panels ...

  7. Prestressed concrete - Wikipedia

    en.wikipedia.org/wiki/Prestressed_concrete

    Prestressed beam with load. Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" (compressed) 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]
