Concrete blocks are often made of 136 concrete with a maximum size aggregate of 10mm or a cement-sand mixture with a ratio of 17, 18 or 19. These mixtures, if properly cured, give concrete blocks a compression strength well above what is required in a one-storey building. The blocks may be solid, cellular or hollow.
This concrete mix ratio of aggregate to sand to cement is an important factor in determining the compressive strength of the concrete mixture.
