About this Episode
Most contractors think warm weather helps speed up a pour—but what if that early strength is fooling you?
In this episode of the Concrete Logic Podcast, host Seth Tandett is joined again by concrete chemist Bob Higgins to break down the real effects of high temperatures on concrete strength, durability, and long-term performance. They cover new science on curing, the shocking impact of temperature on cement hydration, and why most current standards are dangerously outdated.
If you’re pouring slabs in hot weather, this episode could save your project—and your reputation.
