The final phase, capping off the construction of the largest wind farm site in Canada, the Côte-de-Beaupré wind farm is a joint initiative of the Côte-de-Beaupré regional county municipality (MRC) and Boralex, a renewable energy producer.
This is not Béton Provincial’s first foray into the world of wind power. To become an important player in this industry, there are very high quality standards to contend with, and in the concrete industry, requiring a material that is particularly resistant to freeze-thaw cycles.
The essential condition for this strength is entrained air: by creating a network of air bubbles in the concrete used to pour the wind turbine bases, we can make sure that the bases will withstand the rigorous Quebec winters, for their entire useful life. For the Côte-de-Beaupré wind farm, this meant using 4,000 m3 of 30 MPa concrete, with 5 to 8% air.
