Advantages to Precasting

As long as there has been concrete it has been precast-going clear back to the Romans. And there are lots of good reasons for that. The National Precast Concrete Association has information on its website outlining the value of precast concrete.

Most of the advantages they cite are really advantages of concrete in general rather than specific to precast, but when compared to site-cast concrete, precast does have lots of advantages:

- Since precast is manufactured in a controlled casting environment it is easier to control the mix, placement, and curing;

- Quality can be controlled and monitored much more easily;

- Since a precaster can buy materials for multiple projects, quantity discounts can lower costs;

- Weather is eliminated as a factor-you can cast in any weather and get the same results, which allows you to perfect mixes and methods;

- Less labor is required and that labor can be less skilled;

- On site, precast can be installed immediately, there is no waiting for it to gain strength and the modularity of precast products makes

installation go quickly;

- Repeatability-it's easy to make many copies of the same precast product; by maximizing repetition, you can get plenty of value from a mold and a set-up;

- Accelerated curing, by heating the precast parts, greatly increases strength gain, reducing the time between casting the part and putting it into service;

- With the ability to so tightly control the process, from materials to consolidation to curing, you can get extremely durable concrete;
