Effects of salinized triethanolamine as cement grinding aids on particles characteristics and mechanical property of cement were studyed, and its reaction mechanism was analyzed by FT-IR, SEM and XRD. According to the results, when the amount of triethanolamine salinization(DGA) was 0.03%, the sieve residue of 45 ?m was lowered by 47.2%, specific surface area was increased by 45 m2/kg, the particle size distribution of cement which ranges from 3 to 32 ?m increased 10.6%. The compressive strength of cement in 3, 7 and 28 d were increased by 4.9, 5.0 and 3.5 MPa, respectively. Enhancement of DGA on cement mainly lied in that it could promote or induce hydration reaction of cement mineral with gypsum and water, which accelerated formation of hydration products, and then improved the structure and morphology of cement hydration products, thus the uniformity and compactness of hydration products structure increased.
