to develop an permeability apparatus that meets the above criteria,

to assess the value of combining NDT concrete strength evaluation with the permeability tester, in order to improve the accuracy of the concrete quality.

The test method have been successfully used to determine the water permeability of different concrete mixes. The method is based on the determination of coefficient permeability using a water volume of penetration in concrete.

An experimental program, consisting of 27 mixes, was carried out. The vriables assessed were concrete and aggregate strength.
