Study on early hydration in system of cement - coal stone by alternating current impedance spectroscopy
2.
In this paper , the early hydration processes of cement pastes including various contents of coal stone were studied by alternating current impedance spectroscopy

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

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
