Concrete is not often the greenest material choice, particularly since concrete production is one of the largest single sources of carbon emissions globally. But, for wind turbine towers, the use of concrete bases can provide a number of significant benefits, including reducing the amount of concrete needed for the footings for a tower by more than two-thirds. Concrete bases can also be more economical to install and can provide faster construction times for wind towers and also can raise tower height to increase power production.
The wider footprint of the precast concrete base also adds stability to the foundation of the tower. With the precast concrete base, load is spread over a wider area, and a simpler ring footing can be utilized, which results in a 60% - 70% reduction in the concrete needed for the footing of the tower. This can result in a net reduction of the total amount […]
