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 ...
Use of Zeolite as Both Internal Curing Agent and Supplementary Binder in Mortar
Publisher: ASCE
Abstract: Internal curing with sand-like zeolite particles is effective in reducing shrinkage of cement-based materials, but it decreases the compressive strength. In order to obtain cement-based materials with lower shrinkage 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 ...
Multiscale Approach for Mechanical Characterization of Organic-Rich Shale and Its Application
Publisher: American Society of Civil Engineers
Abstract: Mechanical behavior of organic-rich shale strongly influences the stimulation performance of hydraulic fracturing. This article presents an approach for the characterization and evaluation of mechanical properties of shale ...
