  • Portland-limestone cements. Their properties and hydration

    As it was mentioned the produced cements were designed to have the same 28 day compressive strength which varies from 40.3 to 41.2 MPa ( Table 3).The required grinding time and the specific surface (according to Blaine apparatus) of the tested cements are also given in Table 3.As it is seen the PLC requires the higher energy consumption for its grinding while the PFC the lower one.
