CEMENT Portland Limestone Cement UHPC – Ultra High Performance Concrete Today’s Objectives What is a portland-limestone blended cement UHPC Portland-Limestone Cement What is a PLC? Type IL cement 5% to 15% limestone in ASTM C595/AASHTO M240 Ternary cements Why? Option to implement proven technology to obtain desired performance and improve sustainability of concrete History of Use of Limestone in Cements 1965 Cement with 20% limestone cement in Germany for specialty applications 1979 French cement standards allows limestone additions. 1983 CSA A5 allows up to 5% in portland cement 1990 15±5% limestone blended cements routinely used in Germany 1992 UK specs allows up to 20% in limestone cement 2000 EN 197-1 allows 5% MAC (typ. limestone) in all 27 common cements, as was commonly practiced in various European cement standards prior to that. 2000 EN 197-1 creates CEM II/A-L (6-20%) and CEM II/B-L (21-35%) 2004 ASTM C 150 allows 5% in Types I-V 2006 CSA A3001 allows 5% in other Types than GU 2007 AASHTO M85 allows 5% in Types I-V 2008 CSA A3001 includes PLC containing 5%-15% limestone 2012 ASTM and AASHTO include PLC HOW LIMESTONE WORKS Why 15%?
