    The Cement Mechanical Activation Effective Appliion ...
    Of all the known methods for increasing the cement activity, mechanical grinding is distinguished in the work. For mechanical grinding, technological characteristics of grinding in an electromagnetic field are established (mill linear induction rotator, LIV). The value of the increment of activity is determined depending on its initial (initial) value.
