Grinding aids make it possible to streamline the cement-making process by increasing process efficiency and material fluidity. These benefits of cement grinding aid use also contribute to lower energy costs on the part of industrial mills. The grinding aid began to gain popularity in the mid-20th century as a reliable tool for cement processing.
The main function of grinding aids is to partially neutralise the charges present on the surface of cement particles, which develop during milling, reducing the surface free energy of the material being ground. For this purpose, the additive molecules are adsorpted over the surface of the cement particles by weak electrostatic
