Noon – 1:00 p.m. Eastern
Speaker: Nicolas Marks, Continental Cement Company
There recently has been a push from cement companies to switch from Type I or Type I/II cement to Type 1L portland limestone cement (PLC). This change is a part of the cement industry’s goal to lower portland cement’s carbon footprint; however, it may not be clear how this change in cementitious materials may influence fresh and hardened concrete properties. During this webinar, the presenter will dispel some myths and give clear facts about using PLC. He will demonstrate how similar PLC is to Type I/II cement and how it is engineered and manufactured. He will discuss the recommended steps in changing your cement to PLC and how it can still be used with supplementary cementitious materials such as fly ash and slag. Additionally, he will share how PLC’s provisions are currently included in various codes, standards and specifications across the U.S. This presentation will also cover the technical results from various projects, including information related to specifying PLC for use in projects.
At the conclusion of this course, you will be able to:
- Describe how PLC’s chemical properties differ from the cement you are currently using.
- Discuss how PLC hydrates in comparison to Type I/II cement and what that means for fresh concrete properties as well as short- and long-term strength and performance.
- Identify precast-related standards and specifications that already include the use of PLC.
