Mechanism Analysis on Carbonation of Hardened Cement Paste with XCT
Publisher: ASCE
Abstract: X-ray computed tomography (XCT) was used to monitor microstructure changes of hardened cement paste, with different water/cement ratios during a one-dimensional carbonation process. After removing equipment-induced measurement ...
Effects of Calcium Sulfate on Performances of CSA Clinker-Premixed Cl− System: Chloride Binding Analysis
Publisher: ASCE
Abstract: Calcium sulfoaluminate cement (CSA) has excellent chloride (Cl−) binding capacity, which is significantly influenced by the existence of calcium sulfate within mixes. However, impacts of dosage and type of the calcium ...
Simulation Study on Diffusion of Chlorides in Concretes with Load-Induced Heterogeneous Stress
Publisher: ASCE
Abstract: Ingress of chlorides (Cl−) in concretes is influenced by external applied loads, and it is difficult to conduct a quantitative conclusion via experiments due to the geometry of concrete components and their different ...
Binding Mechanism of CSA Cement on Premixed Cl− and Its Governing Parameters
Publisher: ASCE
Abstract: Calcium sulfoaluminate (CSA) cement showed a good binding capacity on the external Cl− transported into concretes from its surrounding environment. However, it is unclear whether the same binding mechanism can still apply ...
