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 ]
The concrete is then settled through vibration to prevent any voids or honeycomb effects. The forms are removed when the concrete is cured; rigging is attached and a crane tilts the panel or lifts the element into place. In circumstances when space is at a premium, concrete elements can be cast one on top of the other, or stack cast.
In Latin America, contractors have started to use a form of lift slab construction where load-bearing concrete walls are raised at the same time as the floor slabs. Both the wall panels and the floor slabs are cast on the ground. The walls are attached to the slabs through hinges formed by plastic ropes.
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.
The first residential building of slipform construction; erected in 1950 in Västertorp, Sweden, by AB Bygging Later picture of the residential building in Västertorp. Slip forming, continuous poured, continuously formed, or slipform construction is a construction method in which concrete is placed into a form that may be in continuous motion horizontally, or incrementally raised vertically.
Formwork is molds into which concrete or similar materials are either precast or cast-in-place. In the context of concrete construction, the falsework supports the shuttering molds. In specialty applications formwork may be permanently incorporated into the final structure, adding insulation or helping reinforce the finished structure.
You won't able to tell by looking when complete, but these affordable homes will be super energy efficient with insulating concrete forms, not lumber. The Village on Walnut in OKC using unusual ...
Slipform stonemasonry produces a hybrid wall of reinforced concrete with a rubble stone face. Natural stone veneers over CMU, cast-in-place, or tilt-up concrete walls are widely used to give the appearance of stone masonry. Sometimes river rock of smooth oval-shaped stones is used as a veneer.
