Concrete Logic Podcast
What is the most used manmade material on Earth? You guessed it – concrete. In each episode of Concrete Logic, we will explore one concrete-related topic with the help of industry professionals that are shaping the future of the trade. We’ll talk with suppliers, contractors, architects, engineers, specialists, and even some proponents of competing materials about their views of concrete and their vision of its future.

What happens when a concrete maturity system is built on the wrong starting temperature? Seth is joined again by Dr. Jon Belkowitz, also known as Concrete Adamus, to explain why datum temperature is one of the most important and commonly overlooked parts of the maturity method.
Jon argues that assuming, ignoring, or defaulting the datum temperature can produce the wrong strength relationship. T…

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,

EP #161: Should We Stop Designing Concrete for 100 Years?
JOIN THE ACADEMY!! FOR A LIMITED TIME, VISIT CONCRETESCHOOL.CO FOR YOUR FREE ACCESS!! CONCRETESCHOOL.CO ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST Should we really design concrete infrastructure for 75 to 100 years? In this episode, Seth is joined by Dr. Jon Belkowitz to question one of civil engineering’s favorite ideas: the 100-year design life. Using Hoboken, New Jersey as the example, Seth and Jon talk about what happens when old infrastructure has to serve a city that no longer looks,

Why Are We Putting Air in Concrete That Will Never Freeze?
The concrete will never freeze. But don’t worry, we tested the air anyway. Let me ask you a simple question. If the concrete is not exposed to freezing and thawing, why are we putting air in it? That question came up during my conversation with D…
