Construction demolitionWhen attached to the excavator, it transforms your base machine into an efficient crushing plant that can process anything from concrete, asphalt, or bitumen to natural stones. After these materials are processed with the ALLU Crusher, they can be reused as fine base material on road foundations, noise barriers, or parking lots.
What Is Crushed Concrete Aggregate and What Is It Used For? · Using recycled concrete in this manner allows for the elimination of concrete in landfills and creates a more sustainable construction material. It also has a smaller carbon footprint than aggregate and takes less energy than mining for aggregate does. This has the side effect of conserving aggregate stock, as it is being used up near big cities.
