JOIN THE ACADEMY! VISIT CONCRETESCHOOL.CO TO START LEARNING TODAY. ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST Are we specifying air entrainment in concrete that does not need it? Seth is joined by Dr. Bruno Fong Martinez, Baker Construction’s concrete materials expert, to examine when air entrainment protects concrete and when it creates unnecessary problems. Air entrainment improves durability where concrete experiences repeated freezing, thawing, and moisture saturation. But Bruno argues...

Most people think moisture problems in concrete come from below the slab. Concrete Bob Higgins explains why that assumption keeps blowing up floors. In this episode, Bob Higgins breaks down how moisture actually moves through concrete, why liquid water and water vapor are not the same thing, and how alkalinity quietly does more damage than most people realize. We also get into why common moisture testing methods are misused, why surface damage matters more than deep readings, and how outdated s...

In this episode of the Concrete Logic podcast, host Seth Tandett speaks with Larry Sutter, principal engineer at Sutter Engineering, about the development of standards and specifications for supplementary cementitious materials (SCMs) like fly ash and slag. They discuss the differences between standards and specifications, the role of fly ash in improving concrete durability, and the challenges of variability in materials. Larry also highlights emerging test methods for evaluating SCMs and the i...

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...
