EP #162: Why This Concrete Expert Wants Air Out of Exterior Slabs
JOIN THE ACADEMY! VISIT CONCRETESCHOOL.CO TO START LEARNING TODAY. ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST Does exterior concrete always need entrained air to survive freezing and thawing? Seth is joined by Jason Adams, founder and CEO of MegaSlab, to challenge that long-standing practice. Jason argues that a properly designed, highly dense concrete system may limit water intrusion enough to reduce the need for entrained air. Seth presses on the risks, including mix design, workability,...

EP #145: The 75-Year Concrete Design Life We’ve Stopped Talking About
We design concrete for 75 years. So why are we okay watching it fail in 12 to 24 months? That’s the uncomfortable question Seth Tandett puts on the table with Dr. Jon Belkowitz in this episode. Codes, specifications, and budgets are still written around a 50–75 year design life. But in the field, concrete surfaces are scaling, wearing, and failing in as little as a year or two. Instead of revisiting that original promise, the industry seems stuck reacting to failures instead of asking why they...
