RISSynergistic-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 ...
Damped Properties and Noether Symmetries of Damped Free Vibration
Publisher: American Society of Civil Engineers
Abstract: This paper focuses on studying the damped properties of damped free vibration for single-degree-of-freedom system by using the Noether symmetries. Based on the Noether theorem, the damping coefficient and amplitude of the ...
Modified Waterborne Epoxy as a Cold Pavement Binder: Preparation and Long-Term Working Properties
Publisher: ASCE
Abstract: The purpose is to enhance the working properties of waterborne epoxy resin and improve the quality of cold pavement binder usage. In this study, a modified waterborne polyurethane/epoxy composite was prepared. The influence ...
