ASCE with Bad Drawings: The Difference between Cement and Concrete

Cement and concrete. Most people use these terms interchangeably and say things like, “I sat on the cement,” or “That building is made from cement.”  However, cement and concrete are actually two different materials and are not analogous to each other.

Cement is a powdered substance (usually grey or white in color) that is made of lime and clay.  Cement is one of the the three main ingredients of concrete.  Specifically, concrete is created when cement undergoes a chemical reaction.  An easy way to remember this is that cement is to concrete as flour is to cake.  I’m confident that you would never use flour and cake interchangeably (especially when ordering desert!), and the same applies for cement and concrete.

    1. Thank you! I actually used very low-grade technology! I filmed this on my Samsung S7 using the “Hyperlapse” video mode. I placed my phone on a barstool and filmed downward at the floor as I drew on graph paper. I pulled the video into Sony Vegas and added the voice over (also recorded on my phone) separately.
