Zhang, Y. (author), Chen, Y. (author), Copuroglu, Oguzhan (author)This paper presents the influence of P<sub>2</sub>O<sub>5</sub> incorporated in slag on the hydration characteristics of cement-slag system. It was found that the gradual addition of phosphorus oxide in slag did not change overall mineralogy of the hydration products. Except hydration retardation in the dormant stage, chemically bound water...journal article 2023
