2018-3-29 Grinding aids for high performance cements Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].

Cement grinding aid used in cement grinding process,Grinding agent in the molecular adsorption on cement particle surface[9-10], between the micro cracks,Can reduce the cement particle surface free energy, and crackle Ca-O ionic bond and covalent bond rupture after Si-O produce unsaturated charge, Stop Ca2+ and O2- back together (theoretical model shown in figure 7), improve the dispersion of fine particles, improve the material liquid inside the mill, improve grinding efficiency. However, the molecular structure of the different grinding agent is different, it leads to the different grinding aid grinding dispersion effect., And cement in different mineral compositions during grinding with different grinding mechanism, Such as C2S mineral need depolymerization, And mineral C3S need crack stress corrosion crack propagation. So in the process of cement grinding, using only a molecular structure of grinding aid can appear the function is not perfect, the effect of one sector. So you need to different molecular structure of grinding aid
