Permeability is defined as the property that governs the rate of flow of a fluid into a porous solid.
0.2 cm/s to 1.2 cm/s as per crouch, 2004

For Rapid Chloride Permeability Test,which is shortly referred to as RCPT concrete size of coarse aggregates will be 3/8" and 3/4" or 10mm and 20mm respectively.

Silt has neither high or low permeability. It has moderate permeability. :) !
Relative permeability is dimensionless
Changes in permeability are changes in the number of compounds that can pass through a membrane. The presence of certain chemicals or radiation can change the permeability of a membrane.
The permeability of coarse sand is 1.89mL/s and the permeability of fine sand is 0.54mL/s.
silica fume and quartz powder is added to make the concrete more denser. fine aggregates fill the voids between coarse aggegates, cement fill the voids between fine aggregate, silica fume fills the voids between cement and quartz powder fills the voids in between silica fumes
The porosity directly correlates with the permeability because the permeability requires a certain level of porosity for a certain measure of it.
