Abstract
Microstructural features, associated with the irreversible loss in strength experienced by immature plain cement paste when exposed briefly to freezing and thawing conditions, have been examined. An important factor is believed to be the formation of large, easily-cleaved portlandite crystals surrounded by stress-intensifying pores. Air-entrained paste, however, contained air voids into which segregation of portlandite occurred during early freezing and thawing.
