    The influence of steel slag on the hydration of cement

    Feb 02, 2011 The influence of steel slag, a by-product from the processing of iron to steel, on the hydration of cement during the hydration process of complex binder was studied by calorimetry, X-ray diffraction analysis, and Ca(OH)2 content determination. The results show that steel slag and cement affect each other’s hydration by changing the hydration environment.get price
