EP #163: How to Fix Air in Concrete
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

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,
