95. Compressive Strength of Concrete
The compressive strength of concrete is very important, as it is used more often in compression than in any other way. It is rather difficult to give average values of the compressive strength of concrete, as it is dependent on so many factors.The available aggregates are so varied, and the methods of mixing and manipulation so different, that tests must be studied before any conclusions can ...

Properties of concrete  Wikipedia
Concrete has relatively high compressive strength (it doesn't crack under weight), but significantly lower tensile strength (it cracks when being pulled). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by additives, typically steel, to create reinforced concrete.
