The distribution of sulfur in present-day clinkers of variable sulfur content
This study focuses on the identification of sulfur-containing phases present in portland cement clinkers from North American cement plants. The clinkers were studied using x-ray fluorescence, x-ray diffraction, and selective dissolution extraction techniques. The samples contained sulfate levels from a few hundredths of a percent to about 2.5 percent. The samples were found to contain alkali sulfates, alkali/calcium sulfates, and some sulfate substituted in the silicate phases. In no case was anhydrite (beta-CaSO4) found. The study concludes that under ambient curing conditions, the sulfur-containing phases present in present-day commercial clinkers are unlikely to cause any internal sulfate attack that might lead to expansive stress and cracking.
