Concrete is one of those things that most of us don't think about much, yet we use it every day. We walk on concrete sidewalks, drive on concrete roads, and live and work in buildings with foundations made of concrete. It is a durable material, that is very strong in compression. The goal of this project is to find out how the ratio of sand to cement changes the strength of concrete.
