Process for Making Concrete


Concrete is comprised of different sizes of aggregate, sand, admixtures, water, and Portland cement. These raw materials are stored in silos or tanks on the site of the concrete plant. A computer-controlled dispensing machine selects and carefully weighs the materials needed to make the concrete mix specified by the client. These materials are then placed in the concrete mixer. While being transported, the drum of the concrete mixer turns on its axis and mixes the concrete. Upon arriving at the construction site, the concrete mix has a uniform, homogenous consistency. Concrete mixer operators deliver the concrete to the site in accordance with the client’s specifications.

The Unibéton, Béton Miroc, Béton 640 and Béton Mercier divisions of Ciment Québec Inc. have stationary plants that make concrete in Quebec, as well as mobile plants that provide complete service to clients.
