Rapid Set Cement for Precast Prestressed Bridge Girder Applications

This study will investigate calcium sulfoaluminate (CSA) cement as a sustainable alternative to portland cement in precast concrete. Compared with portland cement, CSA cement offers a 60% reduction in consumption of natural resources, 50% lower associated carbon emissions, and 35% lower embodied energy. CSA cement offers the additional benefits of very rapid hydration and improved durability over portland cement. CSA cement exhibits setting times between ten minutes and one hour, which will allow precast CSA concrete elements to be cast and demolded in a fraction of the time that their portland cement concrete counterparts require. Since CSA-based materials exhibit improved dimensional stability and resistance to chloride ingress, as well as immunity to alkali-silica reaction and sulfate attack, the durability of the resulting precast elements will be exceptional.
