This report presents the results of a research project commissioned by Austroads to investigate whether the currently used Australian general-purpose (GP) cement which complies with AS 3972, and which may contain up to 7.5% limestone as a mineral addition, could be replaced with a cement proposed by the cement industry, which would contain 12% limestone, could be justified with respect to performance and durability.
