Crushed Brick and Tile
Finely powdered brick can be added to lime mortars to increase strength and improve long-term durability. Pozzolans react with free lime in mortar and lime efflorescence is therefore less likely. Porosity and permeability are both reduced.
Indefinite stored in dry conditions
Fine red/pink powder
To be mixed, normally as a slurry, with lime mortar immediately before use. Add at 5%, 7.5%, 10% or 15% (by volume to mortar) depending on site exposure and the particular circumstances. Do not remix setting mortar.
