Scope

This document describes the method for the determination of the porosity (open pores) of hardened concrete on test specimens of any type (moulded, sawn, cored) or any shape.

The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 40 mm.

The test method is not applicable for concrete containing lightweight aggregate.
