Influence of curing temperature on the process of hydration of supersulfated cements at early age

In this paper, the influence of curing temperature was studied for supersulfated cements made with two slags having different chemical compositions. Supersulfated cements (SSC) made with low-alumina slag developed lower porosity, higher compressive strength and degree of hydration at higher temperatures. SSC made with high-alumina slag resulted in higher strengths and presented a more complex mechanism of hydration that was strongly influenced by the solubility of anhydrite. (C) 2015 Elsevier Ltd.
