The application discloses a
cement grinding aid, and ingredients are as follows in parts by
mass:
fly ash 300-500, organic
grinding component 15-40, inorganic
grinding component 2-8, dehydrating agent 1-3, water absorbing agent 3-6, hydrophobic
silicon dioxide 2-5, and double-end
silane polyethylene glycol 8-13; the application optimizes component matching, improves the ability of the surface of
cement particles to
resist moisture in the mixture, effectively accelerates the absorption and volatilization of
moisture in the mixture, effectively improves the flowability of
cement powder in the mill, and solves the problems of paste ball and mill, reduced yield in the ball milling process of raw materials with high
moisture content, and reduced strength in the application process.
