Moving to Alternative Cements, Concrete Construction Magazine

Oct 18, 2019· In addition to replacing portland cement with alternative cements, another strategy for making concrete more sustainable has been to incorporate recycled materials into the mixture. As with its treatment of alternative cements, ACI 318-19 allows for crushed hydraulic-cement concrete or recycled aggregate to be used in a structural concrete mixCement Milling Understanding Cement,Vertical roller mills (VRMs) are the main alternative means of grinding the clinker and are increasingly being used. For a quick introduction to VRMs see, for example, this advertisement on Youtube for an FL Smidth VRM.
