Abstract: Taking six kinds of alcohol and amine monomer including triisopropanolamine, triethanolamine, propylene glycol, ethylene glycol, diethylene glycol and sorbitol as cement grinding aids, the cement particle morphology, specific surface area, sieve residue mass ratio, particle size distribution and 3 and 28 d cement mortar strength were analyzed with the grinding aids mass ratio of 0.04% and ball-milling 30 minutes. The results indicate that the six grinding aids can improve the grinding efficiency and increase the cement mortar strength.
Keywords: grinding aids; sieve residue; particle size distribution; mortar strength
