The process involves breaking down these raw materials into smaller, uniform pieces, resulting in aggregates with varying sizes and textures.

The mechanically treated granite processing sludge waste acts as pore filler material between the aggregate and cement paste. However, at the 15% cement substitution (10% mechanically treated granite processing waste and 5% silica fume) the flexural strength decreased due to the less cement content in the permeable concrete mix.
