In the production of Portland cement, grinding aids are added in small amounts in the range of 0.01 to 0.10% by weight of cement, according to the PN-EN 197-1 standard . They allow a larger specific surface area to be obtained by the material in a shorter grinding time, which reduces energy consumption.
