    Temperature Dependency Of The Rheological Properties

    failure of CPB structure in the mine stopes due to inappropriate mechanical strength may cause casualties to the mine workers as well as significant environmental and economic damages. Many researchers studied the rheological properties andor strength development of CPB under the individual effect of any of the aforementioned factors.
