STUDY ON THE INFLUENCE OF SOME PARAMETERS OF MIX DESIGN ON THE PERMEABILITY OF HARDENED CONCRETE . DURABILITY OF BUILDING MATERIALS AND COMPONENTS. PROCEEDINGS OF THE FIFTH INTERNATIONAL CONFERENCE HELD IN BRIGHTON, NOVEMBER 7-9, 1990

A study on the different available techniques to test concrete permeability has been carried out by the Laboratorio Central de Estructuras y Materiales. This research programme includes several test methods on laboratory specimens and for in-situ measurements, including the water penetration method. Some operational problems can appear when the test is carried out according to ISO 7031: 1.983. Some modifications were developed to solve them, in order to develop the Spanish Standard UNE 83.309, which deals with this method. The research work also includes a test programme to assess the influence of some parameters of the dosage in the permeability of concrete. The water/cement ratio, the maximum size of aggregate and the curing duration are taken into account. Five test methods are used in the experimental work: water penetration method, initial surface absorption test, the Figg methods to evaluate the air and water permeability of concrete and the Hansen, Ottosen and Petersen's method for permeability of concrete to gases under low pressures. About one hundred and fifty specimens with ten differents dosages were tested. The first experimental results obtained with the two first methods mentioned above, are presented in this work.
