STANDARD TESTS FOR REPAIR MATERIALS AND COATINGS FOR CONCRETE. PART 3: STABILITY, SUBSTRATE COMPATIBILITY AND SHRINKAGE TESTS

The first part of this work describes the properties which need to be quantified or otherwise assessed to ensure compatibility of substrate and repair material when exposed to thermal and moisture cycles of exposure. Thirty four standard test specifications are examined and a further 24 idenfified. A table of comparisons of the tests is provided. The possibilities for strain matching, based upon the results of tests to measure shrinkage, wetting expansion, thermal coefficient, modulus of elasticity and creep are discussed. The basic principles of direct substrate/repair material tests and subjective pass/fail tests are briefly compared. The second part of this work reports on a special study of the best known methods of shrinkage testing. A more detailed comparative tabulation of 12 shrinkage tests is given and reviewed. None of the tests is considered entirely appropriate, and recommendations are made for the development of a test to provide a representative value of expected shrinkage for a range of European exposure conditions. For parts 1 and 2 see IRRD 857880 and 857881 respectively.
