Magnesium industry waste and red mud to eco-friendly ternary binder: Producing more sustainable cementitious materials
Maysa Lorena Figueiredo Martins,Paulo Roberto Ribeiro Soares Junior,Thiago Henrique da Silva,Priscila de Souza Maciel,Ivete Peixoto Pinheiro,Augusto Cesar da Silva Bezerra +5 more
TL;DR: In this paper, the feasibility of using industrial waste (i.e., magnesium industry waste (MW) and red mud (RM) as supplementary cementitious materials was evaluated, and a PC/MW/RM mixture containing 75% PC substituted with 25% of MW and RM was developed as a ternary binder.
