Abstract:
The article discusses various alternative cementitious materials (ACMs) and means for industry acceptance of those materials. ACMs have the potential to provide major reductions in the collective environmental impacts related to concrete production because they can be produced with significantly lower greenhouse gas emissions and energy consumption than portland cement. They can also exhibit improved durability resulting in increased service life. ACMs described in this article include geopolymers, activated glassy cements, hydraulic fly ash cements, activated slag cements, calcium aluminate cements, calcium sulfoaluminate cements, magnesia based cements, and CO2-cured cements.
