Copper tailing as a supplementary cementitious material

Speaker: Dott. Felipe Vargas Muñoz (Pontificia Universidad Catolica, Santiago de Chile)

The use of tailings as aggregate and supplementary cementitious materials (SCM) has been studied, but tailings are generally used as collected, without treatment, showing low cementitious capacity and therefore low replacement levels (below 15% of cement). The purpose of this research was study eight copper tailings collected in different parts of Chile to determine which tailings are likely to improve their cementitious capacity as SCM by using thermal and mechanical treatments.
