Did you know that there are two types of sand that can be used for concrete? In this episode of the Concrete Logic Podcast, Paul Fendley of Active Minerals and Add Ten Gallons Concrete Podcast fame helps us understand the differences between natural and manufactured sand. Depending on where a concrete supplier is in the world, it could realize positive economic and environmental outcomes if it chooses to use manufactured sand.  But wonder if using manufactured sand makes the concrete less user-friendly? What do you do then? Paul might have a solution. As always, thank you to all the listeners that support the show! We hope you gain some value from listening to the Concrete Logic Podcast.
