Made in the UK!


These are pozzalanic additives which we have sourced within Britain.

GGBS (Ground Granulated Blast Slag) is a dry white powder.
PFA (Pulverised Fuel Ash) is a dry grey powder. It is also useful for toning down the colour of a mortar.

Both of these additives are mixed with lime putty based mortar in order to reach a faster initial set similar to a hydraulic lime.
