Hi guys,
I have recently designed some prestressed concrete beams and was looking for some information on how prestressed concrete units are actually made. I have organised a trip to a local facility but was wondering if anyone has some information on the process of making prestressed concrete beams.

Don't they need to wait for the concrete to achieve a design strength before they strands can be cut.

The concrete mixes are highly proprietary for the local materials, products and curing. Normally, a precaster will only use its own mixes since using something different could be in contflict with the PCI certification program. The program is well established through the years and is used by the upper 85% of the industry. The certification is not just the mix design but is a very advanced and monitored quality program that puts the quality variations for poured concrete to shame by a large factor.
