Cast-in-place concrete or Cast-in-situ concrete is a technology of construction of buildings where walls and slabs of the buildings are cast at the site in formwork. [1] This differs from precast concrete technology where slabs are cast elsewhere and then brought to the construction site and assembled. [ 2 ]
Concrete is sometimes used as a fire protection for steel frames, for the same effect as above. Concrete as a fire shield, for example Fondu fyre, can also be used in extreme environments like a missile launch pad. Options for non-combustible construction include floors, ceilings and roofs made of cast-in-place and hollow-core 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.
Franki piles can be used as high-capacity deep foundation elements without the necessity of excavation or dewatering. [4] They are useful in conditions where a sufficient bearing soil can only be reached deeper in the ground, [5] [6] and are best suited to granular soil where bearing is primarily achieved from the densification of the soil around the base.

In situ [a] is a Latin phrase meaning "in place" or "on site", derived from in ("in") and situ (ablative of situs, "place"). [3] The term refers to the examination or preservation of phenomena within their original place or context. This methodological approach, used across diverse disciplines, maintains contextual integrity essential for ...
With concrete work, neat volume is calculated assuming there is no bowing in the formwork, or, for cast-in-place concrete, that the surfaces in contact with the concrete have no voids or imperfections that would require a greater volume of concrete to fill.
Cast stone is commonly manufactured by two methods, the first method is the dry tamp method and the second is the wet cast process. [6] Both methods manufactured a simulated natural cut stone look. Wood, plaster, glue, sand, sheet metal, and gelatin are the molding materials that are used to manufacture drawing work and casting molds like ...
Shells may be cast in place, or pre-cast off site and moved into place and assembled. The strongest form of shell is the monolithic shell, which is cast as a single unit. The most common monolithic form is the dome, but ellipsoids and cylinders (resembling concrete Quonset huts / Nissen huts) are also possible using similar construction methods.
