  • Hybrid cements (HC) are a possible replacement of Portland cement, as their activation process only requires a small amount of sulphates, and is carried out with water at room temperature. The present work aims to study the wear behaviour of HC manufactured from two different wastes: blast furnace slag (HS) and fly ash (HFA). Their wear behaviour was compared to Portland cements (CEM I and CEM IV). Reciprocating wear tests and rolling wear Böhme tests were carried out for pastes and mortars, respectively. Wear tracks in the pastes were analysed through opto-digital microscopy and electron microscopy (SEM). In the mortars, the mechanical resistance was measured to understand different behaviours.

    The results obtained reveal that HC pastes and mortars present lower wear losses than CEM IV and similar to CEM I.
