Concrete and cement are terms that often get used interchangeably, but they don't actually refer to the same thing. Concrete is a composite material made from aggregate, water, and cement, whereas cement is an ingredient used in making concrete. Think of it like the difference between flour and cake - you can use flour to make all sorts of baked goods, but if you're looking for that specific sweet treat, you need to add sugar, eggs, and butter too!
