    Practical implementation of index tests for assessment and control of potential concrete durability
    (Stellenbosch : Stellenbosch University, 1998) Bouwer, Susanna Margaretha; Alexander, Mark; Maritz, Gerhard; Stellenbosch University. Faculty of Engineering. Dept. of Civil Engineering.
    ENGLISH ABSTRACT: An investigation into the validity and practicability of performing the water sorptivity, oxygen permeability and chloride conductivity index tests on actual concrete structures is presented. Each test measures a different transport property of fluids or ions through cover concrete. The resistance of concrete to these transport mechanisms governs the rate of deterioration of the concrete and the embedded reinforcement. Current though is that the tests may assist estimation of potential concrete durability and could form the basis of specifications for the assessment and control of cover concrete quality.
