AbstractCrack growth data for portland cement paste specimens obtained under a variety of environmental conditions indicate that influential factors include humidity, temperature, meniscus rupture events, aging, surface energy changes, hydroxyl ion concentration of pore water, and chemical potential of pore solutions. Possible mechanisms of crack growth involving attack of SiO bonds at crack tips are discussed. Evidence is presented of modification of C-S- H structure by aliphatic alcohols and arguments are advanced for the existence of stress corrosion processes during crack growth in cement paste.
