合成助磨剂对钛矿渣水泥性能的影响

Effect of Synthesized Grinding Aid to Titanium Slag Cement

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, H P E G 400 and other materials were used to composite a new cement grinding aid. W e 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 X R D and T G / D T A indicate that the new grinding aid can promote hydration of cement, but does not produce new phase hydration.
