摘要采用交流阻抗谱方法对掺加不同量煤矸石的水泥浆体的早期水化过程进行了研究。 - Abstract : the formation of traditional v extraction from coal stone isreviewed in hunan province . the paper described several currently applied new processes for v extraction from coal stone . suggestions are put forward for further development of v extraction from the coal stone
文摘:回顾了湖南石煤提钒传统工艺的形成过程，介绍了目前已在生产上应用的几种石煤提钒新工艺，对促进石煤提钒的进一步发展提出了建议。 - It was shown that resistance of pore solution ( r ) and resistance of electrochemistry reaction ( ret ) increased with the prolongation of hydration ages but r decreased with the augment of coal stone . can indirectly reflect the hydration degree of cement pastes
研究结果表明，孔溶液电阻随著水化龄期的延长而增大，但随著煤矸石掺量的增大而减小；电化学反应电阻随著水化龄期的延长而增大，且可以间接地反映水泥浆体的水化程度；分形维数值随著水化龄期的延长而减小，但随著煤矸石掺量的增大而增大。
