Topic: Portland Limestone Cement

Speaker: Nick Popoff - VP of Product Performance and Technical Services, St Marys Cement

Depending on the metrics used and the source of the information, the cement industry is assumed to contribute 5-8% of the man-made CO2 emissions on earth.  Getting to Net-Zero Carbon emissions by 2050 isn’t going to be easy but the cement industry has committed to this initiative.  As such, from a global perspective, we have developed a road-map to get there with interim 2030 targets through the Global Cement and Concrete Association.  Europe has also developed a roadmap to 2050 and recently we have formed a similar committee at the PCA, the Climate and Sustainability Committee to develop our roadmap.  This virtual webinar is intended to highlight one of the most significant contributions to lowering CO2 emissions in North America, Portland-Limestone Cements (PLC).  Introduced into specifications in the US in 2012, it has been available in several other countries around the world for many years and is being promoted for use here.  Nick will introduce us to the development and acceptance work behind PLC.
