Abstract:
This paper provides information concerning the results of test programme to investigate the properties and performance of Type General Purpose (GP) cement containing up to 12% limestone. Cement properties, including chemical and physical properties and mortar properties, such as compressive strength, drying shrinkage, and sulfate expansion were investigated comprehensively for effects of introducing higher limestone content to General Purpose (GP) cement. Test results showed that there is no significant effect on most properties due to increasing the limestone addition in cement from 7.5% to a maximum of 12%.
