Peco (unit)

peco is the unit of measurement of the dielectric properties of concrete and other hydrating materials

The dielectric constant of concrete is about 4.5, but changes with time, as concrete hydrates, and with changes in formulation and/or ingredients.

The unit of peco is derived from the two elements of the dielectric constant (which is a ratio), permittivity and conductivity.
