Resistance to chemical attack of ground brick-PC mortar. Part II. Synthetic seawater
The partial replacement of high C3A cement blended with ground brick (GB) is investigated in terms of resistance of GB mortar to synthetic seawater solution and subsequent strength loss. The results indicate that the resistance of mortar to expansion is generally increased and the loss in strength reduced as the replacement level of cement with GB increases up to at least 30% replacement. However, different GB types, when used as partial cement replacement in mortar, were found to impart different degrees of resistance of the mortar to seawater. These differences are attributed to the variations in the chemical and phase compositions of the GB. Sulfate content, glass content, and oxide chemistry are the principal factors that determine the effectiveness of GB in resisting expansion. Small amounts of sulfate in GB do not have any deleterious effects on GB mortars and can be beneficial.
