Experimental Study of Alkali-Activated Cementitious Materials Using Thermally Activated Red Mud: Effect of the Si/Al Ratio on Fresh and Mechanical Properties

Experimental Study of Alkali-Activated Cementitious Materials Using Thermally Activated Red Mud: Effect of the Si/Al Ratio on Fresh and Mechanical Properties

Bayer red mud (RM)-based geopolymers are economical and ecofriendly alternatives to cement because of their superior performance. This study investigated alkali-activated cementitious materials by combining RM, fly ash (FA) and slag, and the mixtures were used to produce ecofriendly composites. The...
