In this episode of the Concrete Logic Podcast, Seth and Dr. Jon Belkowitz discuss the concrete construction maturity method. The maturity method is an estimation technique that predicts in-place concrete strength based on temperature and time. It involves determining the datum temperature and activation energy, developing maturity curves in the laboratory, and placing maturity meters in concrete elements in the field. The conversation emphasizes the importance of proper preparation and understan...

In this episode, Seth interviews Rich Szecsy, an executive in the concrete supply industry. They discuss the recent change in the batch time for concrete from 90 minutes to 120 minutes. Rich explains the history behind the 90-minute time limit and the lack of scientific justification for it. He emphasizes the importance of considering the practicality and sustainability of construction methods. They also touch on the topic of temperature specifications for concrete and the need for a more nua...

Summary In this Concrete Logic Podcast episode, Dean Craft discusses the topic of concrete moisture vapor emissions. He explains that moisture vapor emissions occur when residual moisture in concrete is released and can cause adhesive bond failures and other issues. Dean emphasizes the importance of addressing moisture vapor emissions early in the construction process and suggests proactive approaches such as using concrete mixes with admixtures to mitigate moisture. He also highlights the limit...
