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. Most precast products are cast in a factory using a wet-cast method, but others are cast on site-such as tilt-up panels.
Advantages to Pre-castingMost of the advantages 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 client 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.
Concrete blocks are a versatile masonry material which can be used in a wide variety of applications. These blocks are produced in mass production lines by KCP which allow homeowners and contractors to purchase them immediately and have them delivered or picked up ready for installation. These blocks are available in many different sizes and designs. They can also be assembled in many different patterns. Concrete blocks are an inexpensive building material which can save homeowners hundreds in the pocket. They are a great alternative to natural stone blocks.
