RISEffect of Interfacial Transition Zone on the Carbonation of Cement-Based Materials
Publisher: American Society of Civil Engineers
Abstract: This study dealt with an analysis of the effects of the interfacial transition zone (ITZ) on the carbonation of cement-based material. To this end, a series of experiments dealing with paste and the mortar-gallet interface ...
Reducing the Carbonation Zone and Steel Corrosion Zone Widths of Recycled Aggregate Concrete by Optimizing Its Mixing Process
Publisher: ASCE
Abstract: The optimization of mixing processes is an effective approach for strengthening the microstructure of the interfacial transition zone (ITZ) in recycled aggregate concrete (RAC). This study used iron oxide to distinguish ...
Monitoring the Evolution of Accelerated Carbonation of Hardened Cement Pastes by X-Ray Computed Tomography
Publisher: American Society of Civil Engineers
Abstract: The evolution of carbonation front progress, crack spatial distribution, and pore structure parameters of hardened cement paste have been monitored in situ by three-dimensional (3D) X-ray computed tomography (XCT) at ...
