WebThe hydration of tricalcium silicate (C 3 S) in the preacceleration stages was studied. The C 3 S particles carry a positive charge during the early stages of hydration. Following a rapid hydrolysis of C 3 S, calcium ions adsorbed on the Si-rich surface of C 3 S particles, greatly reducing their further dissolution, thus initiating the induction period. The [Ca 2+] … WebJan 10, 2024 · This work aims to clarify the influence of potassium hydroxide and sulfate on the hydration progress of tricalcium silicate (C 3 S) from pore solution and solid phase aspect. The early hydration of plain system and C 3 S with alkalis was tested by several …
