Changes in temperature

1. key properties of construction materials

   • Thermal conductivity
   • Thermal resistance
   • Porosity
     • Density
   • Strength
   • Rate of hydration

2. Changes of state

   • Solid
   • Liquid
   • Gas
   • Sublimation

3. Evaporation

   • Gas
   • Vapour

4. Expansion and contraction

   • Water freezing and thawing
   • 'Freeze-thaw cycle'
     • Capillary action
       • Fissures
