Show Notes
In this episode, Seth interviews Mike Hernandez, the Technical Director of the American Society of Concrete Contractors (ASCC), about a survey they conducted on Portland Limestone Cement (PLC). The survey aimed to understand the challenges and differences contractors were experiencing when using PLC compared to traditional cement mixes.
Mike discusses the survey results, which showed increased water demand and set times, as well as changes in plastic and hardened properties. He explains that the next phase of the study involves collecting a large number of mix designs to determine what makes a mix successful with PLC. Mike encourages contractors to submit their successful mix designs to help gather more data.
Takeaways
• The survey conducted by ASCC and ACI on Portland Limestone Cement (PLC) revealed increased water demand and set times, as well as changes in plastic and hardened properties.
• The next phase of the study involves collecting a large number of mix designs to determine what makes a mix successful with PLC.
• Contractors are encouraged to submit their successful mix designs to help gather more data and understand the factors that contribute to successful PLC mixes.
• PLC presents new challenges for contractors, and proper preparation, testing, and curing are crucial to achieving desired results.
