How to Polish Concrete Countertops Concrete Exchange
Concrete is a mixture of cement, rock aggregate, sand, and water. Cement by itself is very brittle, but when rocks and sand are added, a matrix is formed that strengthens the mix. The cement is like the glue, and it fills in the small space between the aggregate and sand. This makes concrete much stronger than cement on it’s own.
