Lime

Portland cement has been the most common type of cement for about a hundred and fifty years. Cement is the key ingredient in concrete and mortar. Lime is a more traditional 'binder' then OPC (ordinary portland cement) and has the following key advantages -

  • Not as brittle - this allows for slight movement
  • Breathable - porous structure that wicks water away
  • Environmental - production uses less energy
  • Environmental - absorbs CO2 as it sets
  • Sustainable - allows masonry to be recycled when the building comes to the end of its life
  • Masonary Friendly - Mortar should be softer then the surrounding stone/bricks as frost damage or thermal expansion should damage the mortar rather then the masonary
  • I'll add more to this section later. For now, here are some useful and informative links-

    Lime colour samples - different types of sand, result in a different coloured mortars
