Pozzolans
We are able to supply a range of pozzolans. These include Brick Dust in 20kg bags, Trass from the Rhineland in 40kg bags, PFA (Pulverised Fuel Ash) in 15 litre tubs and GGBS (Ground Granulated Blast Furnace Slag) in 25kg bags.
The addition of a pozzolan to a non-hydraulic lime mortar can result in an increase in durability. The chemical reaction between the lime and the pozzolan can strengthen the mortar giving it greater resistance whilst carbonation is in progress. Traditional lime putty mortars rely on carbonation for their strength and will as a result be weaker until carbonation has taken place.
It should be appreciated that different pozzolans will affect the lime mortar in different ways.
