Dry cement is typically stored in bulk pressure silos that allow pneumatic transfer of the dry cement to the mixing unit. Cement additive chemicals are either dry blended with the dry cement, or are added in liquid form to the mix water, which is delivered to the mixing unit automatically via the control system.

Production of high-quality, low-permeability concrete is the first line of defense against chemical attack. Admixtures reduce concrete permeability in several ways. They can: permit the use of a lower water-cement ratio; make concrete easier to consolidate; convert soluble hydration products to insoluble ones; fill voids within the cement-paste ...
