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.

It is based on the ultimate strength of the structural members assuming a failure condition, whether due to the crushing of concrete or due to the yield of reinforced steel bars. Although there is additional strength in the bar after yielding (due to Strain Hardening), this additional strength in the bar is not considered in the analysis or design of the reinforced concrete members. In the

The concrete strength is assessed by measuring the crushing strength of cubes or cylinders of concrete made from the mix. These are usually cured, and tested after 28 days according to standart procedures. Concrete of given strength is identified by its “class” a Class 25/30 concrete has a characteristic cylinder crushing strength (f ck) of 25 N/mm 2 and cube strength of 30 N/mm 2. Table
