1. Abstract

This paper describes a water permeability test system aimed at promoting concrete durability research. It features a dual-test method for the measurement of water permeability with the standard 150 mm test cube prior to the determination of compressive strength. It is incorporated with an integrated calibration system for pressure and displacement. The calibration of the test system is by means of a mature test cube of known water permeability. The test system plays complementary role to the existing methods of assessing durability such as carbonation test and rapid chloride permeability. The test method is non-destructive, convenient and reliable for assessing concrete durability in the laboratory at the mix design stage. It can be used subsequently for in-situ tests on concrete structures during construction. It is also useful for research into precast concrete piles and cement-lined pipes and fittings for waterworks which are subject to water pressure. Information technology has been experimented to provide online skill training and the electronic publications of research findings to promote good concrete practice.
