Portland-limestone cement
In Europe, portland cement is considered a premium product, as low clinker cements (i.e. cements with a low clinker-to-cement ratio) are more prevalent than in North America. European cement standards allow up to 35% limestone content in PLC, which can restrict the use of such concrete mixes to select applications as limestone content increases.
