Equivalent Durability Performance of Portland Limestone Cement
Portland limestone cement (PLC) has become increasingly accepted around the world. PLC is able to be manufactured to have equivalent performance to portland cement (PC) in terms of strength and durability, and, therefore, it can be used as a replacement for PC. However, there have been a few concerns regarding a total transition from PC to PLC due to areas lacking in research. Blends of PC and supplementary cementitious materials (SCMs) have been used to provide resistance to alkali-silica reaction and sulfate attack, but there is little data yet on the performance of PLC and SCM blends. There has been little research on whether PLC concrete is as resistant to cyclic freezing and thawing as PC in situations that are less than ideal, such as when poorly constructed materials lead to increased water content. Research on carbonation has provided ambiguous results. This article presents recent findings in this area that verify PLC's resistance to alkali-silica reaction, sulfate attack, cyclic freezing and thawing, and carbonation.
