Rheology of pure and mineral admixture modified cement pastes and their degradation due to calcium leaching

摘要：

　　This paper is to deal with the modeling of compressive strength of leached pastes subjected to aggressive lechant.Firstly,rheology testing was performed on fresh pastes by using Con-Tec Viscometer.The slump flows in relation to rheological parameters were obtained.Then uniaxial compressive test was carried out on both well-preserved and corrosive pastes.The loss of compressive strength has a significant linear correlation with leached ratio for all pastes specimens.Finally,a prediction model forecasting reduction in strength was proposed.
