Overview

Evaluates a kaolinite admixture that enhances early strength in concrete, indicating practical applications in construction.

Key Points

  • The research aims to develop a kaolinite-based admixture to accelerate early-stage hardening of high-strength concrete.
  • Developed a low-dosage kaolinite-based admixture (2 wt% of cement)
  • Conducted compressive strength tests at 3 and 28 days
  • Utilized FT-IR, WD-XRF, XRD, and XPS analyses to explore hydration mechanisms
  • Increased compressive strength by about 61% at 3 days
  • Achieved more than 30% increase in compressive strength at 28 days, reaching nearly 44 MPa
  • Demonstrated rapid formation of a compact C-S-H network
  • Reduced water absorption supports microstructural densification
