Thermoactivated cementitious materials – A review
https://orcid.org/0000-0003-2552-8437
Highlights This review is a useful and timely contribution to the study of cement recycling. This review portrays the state-of-the-art of research on thermoactivated cement. Describes production strategies of recycled cement by thermal activation and rehydration. Describes main issues hindering application: higher water demand and fast setting. Addresses potential of rehydrated cement towards low carbon, closed cycle concrete.
Abstract Cementitious materials can regain hydraulic binding properties when thermally treated at high temperature, and this potential has been explored to obtain a new type of recycled binder. The current article examines the main phases involved in cement dehydration and rehydration and the dehydration kinetics. Main production issues, including reduced setting time and excessive water demand, and collected mechanical results are also described. The possibility to synergistically use thermoactivated cement with ordinary Portland cement and mineral additions to overcome some of the main current challenges reported in the literature is analysed. Overall, thermoactivated cements show great potential as a stepping stone towards fully recyclable concrete.
