Concrete is what you make a sidewalk from. To make concrete, you mix Portland cement, sand, gravel (aggregate) and water. The cement holds the aggregate together.

What stronger brick or cement?

http://simscience.org/cracks/advanced/concrete2.html A common mistake people make is to use the words cement and concrete interchangably. It is important to remember that cement is only a component of concrete and concrete is the structural material. The cement used in concrete is not used as a building material because it would be too expensive and not as strong as concrete. So when you see a parking garage, a driveway, a sidewalk or a road remember it is made of concrete, not cement. And, by the way, that funny looking truck is a concrete mixer, not a cement mixer! But, if cement is not concrete, then what is it? Cement is a general name for a material that binds other materials together. Yes, it is another name for glue. There are many materials which we would classify as cements and they are usually identified with certain uses, and can produce different types of "concrete". The type of cement used to make the riding surface of some of our roads (blacktop!) is called asphalt cement. It is a petroleum bi-product, and it binds rock into the road material we call asphaltic concrete.
