Abstract
Recent site and laboratory investigations have shown that the mineral thaumasite has been responsible for the deterioration of concretes and mortars specifically designed to give good sulfate resistance. It has been shown that thaumasite may form if concretes containing commonly used limestone aggregates are exposed to a source of sulfate (such as groundwater). Therefore there is a need to establish a type of limestone aggregate concrete which can resist this form of sulfate attack. Previous work carried out indicated that the use of blastfurnace slag cement could improve the resistance of limestone aggregate concretes.
