| Abstract: | Based on systematically studying Dale＇s model, the applicability of the Dale＇s model for saturated curing and sealed curing was investigated. By analyzing influencing mechanism of fly ash to cement hydration, the fly ash influence coefficient＇s Notion was put forward. Based on issued experimental results, Influence coefficient formula was derived, the hydration kinetic model of Portland cement-fly ash pastes was established. |
