Concrete as a Building Material | Reinforced Cement ...
If an engineer specifies M30 / 20 concrete, he wants M30 concrete with a maximum aggregate size of 20mm. He does NOT want concrete with a strength of between 20-30 n/mm2, which is a common misinterpretation in some parts of the world. Concrete that is cast in place in its mould is called cast-in-situ concrete.
