MEASURES DISCUSSED FOR REDUCING CONCRETE EXPANSION WHEN REACTIVE CARBONATE AGGREGATES, PARTICULARLY ARGILLACEOUS DOLOMITIC LIMESTONES, MUST BE USED, ARE' 1/ REDUCTION OF THE CEMENT ALKALIES, AND 2/ DILUTION OF THE REACTIVE AGGREGATE WITH NON-REACTIVE AGGREGATE. THE MAIN EMPHASIS IS PLACED ON VOLUME CHANGE, THE PROPERTY MOST SIGNIFICANTLY AFFECTED BY THE REACTION. VOLUME CHANGES ARE BEING STUDIED FOR THREE EXPOSURE CONDITIONS' TWO IN THE LABORATORY AND ONE IN AN OUTDOOR TEST AREA. THE MEASURES… CONTINUE READING
