### What is the density of cement?

Normal concrete has a density around 2400 kg/cubic meter or 4048 lb/cubic yard. There are many different kinds of concrete, many of which are much lighter. Cement is the liquid (or paste like) form, and tends to be much heavier than when it has cured into concrete. "Cement" is not concrete, but can be used to make concrete by mixing with sand, stone and water. The density of cement is about 3120kg/m3.

### How much PSI takes to brake concrete?

Generally speaking, concrete is rated anywhere from 2000 psi to 10,000 psi. Of course if you do NOT use the proper ratio of aggregate (usually sand) to cement and water you can make concrete that is even weaker. When concrete is ordered from a delivery company, you specify the strength of he mix or pour that you want.
