Precast Concrete is Durable
Concrete is tough and durable. Precast concrete, in particular, is even stronger because it’s manufactured in a controlled environment with a more exact mixing, molding and curing process. This results in greater strength and uniformity better resistance to elemental changes. It’s impervious to fire, water and termites. It doesn’t rust, rot or fade away over time.
This requires high cement contents and low water-cement ratios. Combined with good com- paction and curing in a controlled factory environment, these factors ensure a dense, highly durable concrete. A low water-cement ratio has been proven to increase resistance to weath- ering and corrosion. Entrained air may be used to improve freeze-thaw resistance in particu- larly severe environments.
