The Application of the Fly Ash Excitated Grinding Materials

Article Preview

Abstract:

The fly ash of non grade with low activity can not be directly used in the cement concrete. After a lot of tests, several kinds of fly ash grinding excitation materials were chosen to be ground together with fly ash of non-grade and low activity. The studies show that three kinds of fly ash grinding excitation materials A, B, C can not only decrease the water demand ratio but also increase the activity index of the polished ash as well. All other indexes meet the requirements of technical specification standards for fly ash gradeI. Based on the effect of excitation activity and economic benefits, the fly ash grinding material B was chosen as the main active materials for the power plant to make excitation ash,the fly ash composite materials can be widely used in cement concrete with high activity index and great benefits, and the problems for the application of the long-term piled fly ash can also be solved .
