- Abstract
- Blended cements containing fly ash and blast furnace slag along with admixed periclase were examined using autoclave curing as specified by ASTM C151 and long-term immersion curing to assess their expansions as a function of the curing conditions. In some instances, measurements of linear expansion were combined with compressive strength measurements. The partial replacement of portland cement by fly ash while maintaining a fixed periclase content was found to significantly reduce expansion as measured by ASTM C151. Partial replacement by fly ash was also found to reduce the expansions which occurred as a result of long-term immersion curing. However, significantly larger expansions were observed in the latter case. (ERA citation 09:010143)
