Experimental Data on CO2 and Chloride Interaction in Nickel Slag Geopolymer Mortar

A 26.2 KB document published on figshare by Zhihang Qu on 2026-05-04. It contains experimental results investigating the combined effects of carbonation and chloride ion penetration on the durability of one-part nickel slag geopolymer mortar. The study assessed macro-performance via compressive strength, pH, and chloride concentration, and analyzed microstructural mechanisms using XRD, TG-DTG, and SEM.

Use Cases

• Modeling the synergistic degradation of geopolymers based on the described interaction between carbonation and chloride ions.
• Analyzing microstructural changes in cementitious materials based on XRD and TG-DTG results mentioned in the description.
• Comparing durability test protocols based on the three experimental conditions (A, B, C) outlined in the study.
• Investigating chloride binding mechanisms in alkali-activated materials based on the finding that chloride was captured primarily through physical adsorption.

Strengths

• The dataset is openly licensed under CC-BY-4.0, permitting broad reuse.
• The description details specific experimental conditions and analytical techniques (XRD, TG-DTG, SEM) used.
• Key findings, such as the delay of carbonation by chloride crystallization, are explicitly stated.

Limitations

• The dataset is very small (26.2 KB), suggesting limited raw data or a primary focus on textual results.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative modeling.
