• Abstract:

  A fundamental advantage of precast concrete is that it is produced at a factory in quality-controlled environment. Since every piece must be shipped to another location, precasters are often required to limit the weight of each shipment due to highway weight restrictions. These restrictions limit the number of units that can be placed on each shipment, even if more space is available of the truck or trailer.
  One alternative that allows you to include more products with each shipment is to use concrete that weighs less. Since aggregates make up a significant percentage of the weight of concrete (60 to 70 percent), it makes sense to focus on them. Besides, although there is such a thing as lightweight cement, it is not widely available. And who has ever heard of lightweight water?
