Geopolymer Specimens from LD and LF Steel Slag with KOH Alkaline Solution

A study by Ana Paula Pereira investigated geopolymers synthesized from Linz Donawitz (LD) and ladle furnace (LF) steelmaking slags using an 8M potassium hydroxide solution. Specimens were produced at three solid/liquid ratios (1.2, 1.4, and 1.6 g/v) and analyzed via XRF, FTIR, TGA, SEM-FEG, and Archimedes' principle. The results indicated that the 1.6 ratio samples exhibited more cohesive appearance and higher densification.

Use Cases

• Predicting material densification based on solid/liquid ratio mentioned in the description
• Analyzing thermal stability of geopolymers based on TGA results mentioned in the description
• Characterizing microstructure and porosity based on SEM-FEG and Archimedes' principle analyses mentioned in the description
• Comparing crystallinity phases between LD and LF slag-derived geopolymers mentioned in the description
• Optimizing geopolymerization process parameters for engineering applications mentioned in the description

Strengths

• Specimens were synthesized at three distinct solid/liquid ratios (1.2, 1.4, and 1.6 g/v)
• Multiple analytical techniques were applied (XRF, FTIR, TGA, SEM-FEG, Archimedes' principle)
• The study uses a specific 8M potassium hydroxide (KOH) alkaline solution

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment
