Although aggregates are most commonly known to be inert filler in concrete, the different properties of aggregate have a large impact on the strength, durability, workability, and economy of concrete. These different properties of aggregate allow designers and contractors the most flexibility to meet their design and construction requirements.
If and when aggregates are extracted from below the established water table it will have impacts on the fragile environment and its natural features. The application process requires that the potential impacts of a proposed development be reviewed and assessed. It is critical that
