JOIN CONCRETE SCHOOL FOR FREE AT CONCRETESCHOOL.CO! ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST 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. That...

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...

EP #139: Concrete Reality Check - INDOT Calls Out the Cement Industry
Indiana just told the cement industry it won’t accept any blended cement with more than 10% limestone. That’s a first - and it’s not sitting well with the people who pushed Type IL cement in the first place. For the first time, a state DOT pushed back on Type IL cement—and the industry fired back. Indiana’s Department of Transportation says it’s protecting performance after bridge decks started scaling. The American Cement Association says the DOT’s new limits are unnecessary, confusing, and un...
