In this episode of the Concrete Logic Podcast, Paul Ramsburg of Sika continues his lesson on the history of concrete. We pick up our discussion in the 1800s when the first concrete flooring contractor got started. We learn where the first reinforced concrete structure was built, why concrete arrows were an aviation necessity back in the day, and what concrete ships were used for during World War II. Plus, you will learn other concrete historical tidbits that I am sure you didn't know. This is Part 2 of our two-part concrete history series with Paul Ramsburg. If you have not listened to EP #011, you will want to listen to it first before you listen to this episode.  Episode References  Guest: Paul Ramsburg, Sika, ramsburg.paul@us.sika.com Guest website:  https://usa.sika.com/ Host: Seth Tandett, seth@concretelogicpodcast.com Host website: concretelogicpodcast.com
