Here is our research about concrete.

The other day a concrete mixer came to school, and it made us think: What is concrete? and How is concrete made?

How do you make concrete?

To make concrete the ingredients are water, sand, cement and gravel. Normally you use one part of cement, two parts of sand and three parts of gravel. You combine them all together while dry and then you mix with about half a part of water. If there is not much cement it is called sandcrete. Concrete can be made for lots of things and it is a good subject for learning.
