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 lifted into place. In contrast, standard concrete is poured into site-specific forms and cured on site. Precast stone is distinguished from precast concrete by using a fineaggregate in the mixture so the final product approaches the appearance of naturally occurring rock or stone.
By producing precast concrete in a controlled environment (typically referred to as a precast plant), the precast concrete is afforded the opportunity to properly cure and be closely monitored by plant employees. Utilizing a Precast Concrete system offers many potential advantages over site casting of concrete. The production process for Precast Concrete is performed on ground level which helps with safety throughout a project. There is a greater control of the quality of materials and workmanship in a precast plant rather than on a construction site. Financially, the forms used in a precast plant may be reused hundreds to thousands of times before they have to be replaced which allows cost of formwork per unit to be lower than for site-cast production.
Many states across the United States require a precast plant to be certified by either the Architectural Precast Association (APA), National Precast Concrete Association (NPCA) or Precast Prestressed Concrete Institute (PCI) for a precast producer to supply their product to a construction site sponsored by State and Federal DOTs.
There are many different types of precast concrete forming systems for architectural applications, differing in size, function and cost. Precast architectural panels are also used to clad all or part of a building facade free-standing walls used for landscaping, soundproofing and security walls and some can be Prestressed concrete structural elements. Stormwater drainage, water and sewage pipes and tunnels make use of precast concrete units. The New South Wales Government Railways made extensive use of precast concrete construction for its stations and similar buildings. Between 1917 and 1932, they erected 145 such buildings.
Magnetic Blocks, Magnetic Boxes, Button Magnets, Shuttering Magnets, Magnetic Shutters, Magnetic Force 600 to 2100 kg Shuttering Magnet Magnetic blocks are fixed by a push button on the shuttering. Advantages of the magnetic block locking system are for locking of shuttering profile for faster precast cast molding cycle. The magnetic block are selected according to lengths and height of shuttering profile. Magnetic block […]
