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 ]
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.
Reinforced concrete can be classified as precast or cast-in-place concrete. Designing and implementing the most efficient floor system is key to creating optimal building structures. Small changes in the design of a floor system can have significant impact on material costs, construction schedule, ultimate strength, operating costs, occupancy ...
The Filigree Wideslab method is a process for construction of concrete floor decks from two interconnected concrete placements, one precast in a factory, and the other done in the field. The method was developed during the late 1960s by Harry H. Wise as a more efficient and economic construction process than conventional cast-in-place ...
Reinforced concrete can be precast or cast-in-place (in situ) concrete, and is used in a wide range of applications such as; slab, wall, beam, column, foundation, and frame construction. Reinforcement is generally placed in areas of the concrete that are likely to be subject to tension, such as the lower portion of beams.
In situ: Formwork construction and pouring of concrete occur on site, then the slab is assembled (if required). [4] Precast: The slabs are made somewhere else and then brought to the site and assembled. [4] Pre-fabricated: The reinforcements are integrated into the slab while being manufactured, without needing to reinforce the assembly on site ...
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]
[32] [36] Solidia Technologies fires its brick and precast concrete at lower temperatures and cures them with CO 2 gas, claiming to reduce its carbon emissions by 30%. [32] [36] Carbonaide uses carbon dioxide in the curing phase of precast concrete production and has demonstrated up to 40% savings in cement consumption with their first client. [39]
