采用三异丙醇胺、二乙醇胺、丙烯酸、HPEG400等原料合成了一类新型水泥助磨剂,检测了对钛矿渣水泥的助磨效果、物理力学性能和水化产物的影响.结果表明,加入助磨剂后,钛矿渣水泥的比表面积提高了9.5%~14.7%,3 d和28 d抗压强度分别提高了9.0%~21.2%和7.2%~10.6%.XRD和TG/DTA的测试结果表明,新型助磨剂能促进水泥水化的进行,但并不会产生新的水化相.
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.
