Silica fume for permeable concrete

Permeable concrete is also known as porous concrete, sandless concrete, permeable flooring. A porous, lightweight concrete made from aggregates, cement, enhancer, and water that contains no fine aggregates.

Permeable concrete is a honeycomb-like structure with a uniform distribution of holes by a thin layer of cement slurry covered with a thick aggregate surface, so it is characterized by breathability, permeability and light weight.
