Use of Pozzolan or Slag in Concrete to Control Alkali-Silica Reaction and Sulfate Attack
Five different materials (one Class C fly ash, two silica fumes, and two ground granulated iron blast-furnace slags (slag) were characterized by a combination of tests, standard physical and physical plus some petrographic examination. Mortar mixtures were then made using different amounts of each of these materials with high-alkali portland cement. Specimens from these mixtures were tested for expansion due to alkali-silica reaction (ASR) by CRD-C 257 (ASTM C 441) and for expansion due to sulfate attack by CRD-D 211 (ASTM C 1012). The expansion data were evaluated to determine the amount of each material required to control either process or the combined effects of both. A few concrete mixtures were then made using the indicated amounts of the fly ash, silica fume, and slag, and specimens were tested as before to determine the effectiveness of these materials to control deleterious expansion in concrete. Keywords: Alkali-silica reaction, Fly ash, Natural pozzolan, Pozzolan, Silica fume, Slag, Sulfate attack. (JES)
