On what proportions and grade cement is included in the composition of the concrete, depends on the strength and resistance to deformation of the latter. This calculator helps to estimate the amount of cement for the preparation of 1 cube of concrete mortar of the selected grade. The tool also provides data on the proportion used, as well as the consumption of other components of the mixture. Dry mix is taken equal with a density of 1300 kg/m3.
