Abstract: Triisopropanolamine, diethanolamine, acrylic, HPEG400 and other materials were used to composite a new cement grinding aid.We examined the grinding effect of the new grinding aid for titanium slag cement, and the physical and mechanical properties and the hydration products of the cement were studied.The results show that the surface area of titanium slag cement increase of 9.5%-14.7%, 3 d and 28 d compressive strength respectively increased by 9.0%-21.2% and 7.2%-10.6% after adding this new grinding aid.The test results of XRD and TG/DTA indicate that the new grinding aid can promote hydration of cement, but does not produce new phase hydration.
