Abstract:
This paper presents results from a field study on the use of portland limestone cement (PLC) in exposed concrete flatwork. Eight concrete mixtures were produced using PLC, a control portland cement (PC) produced from the same clinker and different levels of supplementary cementitious materials (SCM). Tests included strength, chloride permeability, freeze-thaw, salt scaling, and chloride diffusion. The results indicate that concrete performance is strongly influenced by the level of SCM used but is independent of whether PLC or PC is used. The use of such PLC has the potential to bring about a 10% reduction in the greenhouse gas emissions associated with the production of PC clinker.
