Report on Permeability of HardenedAssignment Point

Permeability of concrete is a complex field of study, since concrete is a heterogeneous blend of materials. Furthermore the concrete properties change with age. Permeability is the ability to transport different fluids or gases, like water, chlorides, sulfates or oxygen. There is a good relationship between w/c ratio and the permeability.

Complex geological environments, on the other hand, can lead to more complex saturated-unsaturated conditions. The existence of a low-permeability clay layer in a high-permeability sand formation, for example, can lead to the formation of a discontinuous saturated lense, with unsaturated conditions existing both above and below.

Vacuum permeability Wikipedia

The physical constant μ 0, (pronounced "mu nought" or "mu zero"), commonly called the vacuum permeability, permeability of free space, permeability of vacuum, or magnetic constant, is the magnetic permeability in a classical vacuum. Vacuum permeability is derived from production of a magnetic field by an electric current or by a moving electric charge and in all other formulas for magnetic

What is permeability (magnetic permeability)? Definition

The permeability factors of some substances change with rising or falling temperature, or with the intensity of the applied magnetic field. In engineering applications, permeability is often expressed in relative, rather than in absolute, terms.
