Influence of P(AA-AMPS-AM) intercalated Ti-Li-Al-layered double hydroxide on the properties of sulfoaluminate cement-based grouting materials

Key Points

• The research aims to explore how the addition of P(AA-AMPS-AM) intercalated layered double hydroxide influences sulfoaluminate cement-based grouting materials.
• Investigated the dispersion stability of layered double hydroxides (LDHs) with APM
• Analyzed the effect of APM-RLDH on nucleation sites for AFt and AFm formations
• Studied the dissociation of APM-RLDH at pH 12.5 and its impact on particle size reduction of aluminum gel.
• APM significantly enhances the dispersion stability of LDHs
• APM-RLDH provides effective nucleation sites for both AFt and AFm phases
• Dissociation of APM-RLDH at pH 12.5 releases APM polymer, promoting AFt formation while reducing aluminum gel particle size.
