RISEffects of the Ion Exchange and Adsorption Behavior of Clinoptilolite on Chloride Solidification in Cement Paste
Publisher: American Society of Civil Engineers
Abstract: Clinoptilolite has been used in cement-based materials to reduce shrinkage and increase compressive strength, but the ion exchange and ion adsorption behavior of clinoptilolite in cement-based materials have not been ...
Hydration Kinetics and Performance of MgO-Activated Slag Binder with Available Carbonate and Silicate
Publisher: American Society of Civil Engineers
Abstract: The combination of magnesium oxide (MgO) with various reactive aluminosilicates has recently been studied as an alternative binder, which bridges the chemistry of alkali-activated materials containing reactive MgO and ...
Synergistic-Inhibition Mechanism of MgO and Na2CO3 as Alkali Activator: Hydration–Hardening Characteristics of MgO─Na2CO3–Activated Slag
Publisher: American Society of Civil Engineers
Abstract: MgO and Na2CO3 are used instead of strong alkalis (e.g., NaOH, NaOH+Na2SiO3) to prepare alkali-activated slag cement, achieving the promotion and use of green-economic alkali activators. In this study, the hydration ...
