SULFATE RESISTANCE OF CONCRETE CONTAINING FLY ASH. DURABILITY OF CONCRETE. G.M. IDORN INTERNATIONAL SYMPOSIUM, 1990 ANNUAL ACI CONVENTION, TORONTO, ONTARIO, CANADA
In order to clarify the effect fo different types of fly ash on concrete exposed to sulfates, a research project is currently being conducted utilizing fly ash from 15 different sources. These fly ashes include sources from bituminous, subbituminous and lignite coal powered electric generating plants that generally conform to the requirements of ASTM C 618, Class F or C fly ash. The fly ashes are categorized by both chemical and mineralogical phase composition. A Type II portland cement is bieng used with a fly ash replacement level of 35 percent by volume. The sulfate exposure test consists of concrete cylinders soaling in a ten percent sodium sulfate solution. Performance is measured by mass loss, expansion and visual inspection of concrete specimens.
