| 摘 要： | 通过测定不同龄期煤矸石地酸溶出量,对不同温度热激活下的煤矸石在煤矸石-Ca(OH)2-H2O体系中的反应速率进行了研究,并在此基础上建立了煤矸石火山灰反应动力学模型.该模型表明:煤矸石的反应速率(v)主要取决于煤矸石的火山灰活性(v),值大则煤矸石的火山灰活性高,反应速率常数k值大则煤矸石的火山灰反应活性高,最后采用Ca(OH)2的吸收实验来验证本模型的正确性.

| Abstract: | In this paper, the reactive velocity of coal gangue calcined at different temepratures was studied in the system of coal gangue-Ca(OH)_2-H_2O.On the base of the reactive velocity of coal gangue, the model of coal gangue pozzlantic reaction kinetics was presented. It is suggested that the reactive velocity should be decided by the pozzlantic activation of coal gangue, the reactive velocity increases with a rise in the pozzlantic activation; the reactive velocity constant also boosts with the elevation of the pozzlantic activation. |
