How is precast concrete made?
Precast concrete is made in a factory, where a dedicated batch plant produces a specially designed concrete for precast products such as structural beams, columns and double tees, architectural cladding, and wall systems. Aggregates usually come from nearby quarries, and cement and other ingredients are often supplied by local manufacturers. The mixed concrete is placed into a form around reinforcement and, often, prestressing strands that provide load-resisting camber to the finished precast concrete member. After the member is cured, the precast concrete product is stripped from the form and moved to the precaster s yard for finishing and storage prior to shipping to the jobsite.
