3. Massive concrete structures
There is no standard definition of what constitutes a massive structure. However, it can be assumed that a massive structure is one whose smallest dimension is at least 60 cm (LCPC, 2003).
In recent years, the use of solid concrete elements has become widespread. As a general rule, solid concrete has been associated with large structures such as dams. However, other structures, such as the bases of cable-stayed bridge pylons or the foundations of nuclear power plants, may also have solid parts. The need for methods involving rapid cycles (for formwork rotation, part handling, prestressing for pushed bridges, etc.) has also led to parts with high early-age temperatures.
The formulation of a mix for mass concrete pours can vary considerably depending on the type of structure, the environment, and the resources available. From harsh winter...
