Implication

Randomized trial examines hydration and performance of polymer-modified mortars, suggesting enhanced repair applications.

Key Points

  • The study aims to explore how different polymers affect the properties and hydration mechanisms of high-belite sulfoaluminate cement-based mortars.
  • Utilized high-belite sulfoaluminate cement with natural river sand as fine aggregate.
  • Compared effect of VAE and HPMC polymers on mortar performance and hydration.
  • Conducted mechanical tests for flexural strength, compressive strength, and bond strength.
  • 5% VAE increased mortar flowability by 29.8% and improved 28d bond strength by 56.7%.
  • 0.1% HPMC delayed initial setting time by 6.5 min, achieving over 90% water retention rate.
  • Both polymers improved bond strength but generally reduced flexural and compressive strengths.
