The analysis is focusing on collecting and investigating samples of lime mortars and plasters from different historic periods of Ayutthaya, as well as those from modern interventions.

Objectives of the analyses:

  • Physical properties
  • Mineral or chemical properties
  • Mechanical properties
  • Decay mechanism

Involving in total 11 sets of scientific testing:

  • SEM-EDS
  • Optical microscopic observation
  • Thin section analysis
  • Colour and texture testing
  • Mercury intrusion and water absorption capacity
  • Capillarity
  • Permeability
  • Chemical content measurement (calcimeter, XRD etc.)
  • Wet-dry cycles
  • Salt analysis (quantitative, qualitative, crystallization) 
  • Compressive strength
