高掺量粉煤灰水泥的研究

Experimental study on optimal gypsum charge into cement in Luonan Cement Plant

本文通过试验,研究了复合激发剂、石膏、粉磨细度等对粉煤灰水泥强度性能的影响。结果表明,选用适当的复合激发剂,并相应地提高粉磨细度,可以明显地提高粉煤灰水泥的强度,尤其是早期强度。从而达到提高粉煤灰水泥中粉煤灰掺量的目的。

: In this article, the experimental study of gypsum charge into the cement in Luonan Cement Plant is presented.The tests show that, generally speaking, the SO3 charge shall be within 1. 8%-2, 5% in ordinary cement and 2.0% - 3.0% in slag cement produced in this plant. In the article, the impact of the gypsum charge upon the cement properties is studied, and the analysis of the gypsum charge is also made by relating to the cement fineness, C3A content and sintering system. The author proposes the way to determine the optimal charge by test.
