Concrete Applications

Changing the density allows concrete to be used for non-traditional applications. Lightweight concrete reduces the weight of the finished structure and improves thermal insulation. Heavyweight concrete (which contain barite) is used where high mass is required on a limited volume (e.g. counterweights).
