with Portland-Limestone Cement: Canadian Studies Michael D.A. Thomas1 and R. Doug Hooton2 INTRODUCTION Portland-limestone cements (PLC) have been allowed by the European Standard, EN197-1, since its adoption in 2000, although a number of European countries allowed their use through national standards for a decade or more prior to this date.
Portland-limestone cement is engineered with a higher limestone content. PLC (Type IL) gives specifiers, architects, engineers, producers, and designers a greener way to execute any structure, paving, or geotech project, with virtually no modifications to mix design or placing procedures.

Portland limestone was formed in a shallow, warm, sub-tropical sea on the continental shelf of what is now western Europe. Limestones are mostly made of calcium carbonate. This comes originally from the bodies of many small organisms which build their shells or framework out of CaCO 3 crystals. An example is the type of protist called ...

European producers embraced Portland-limestone cement (PLC) decades ago. In the mid-1960s, German producers experimented with PLC for certain specialty applications. They experimented with mixtures including up to 20 percent limestone. By 1990, blended limestone cements were widely used in Germany. In 1992, the United Kingdom followed suit.
In many European countries (e.g. Italy, France, Switzerland) portland-limestone cements (PLC) are broadly accepted and have reached a market share of much more than 60%. Two circumstances encouraged this development: The local availability of limestone - and the low volumes of other SCMs; The European …
