Argical M1000 (metakaolin) is a reactive artificial pozzolan produced by calcining china clay. Pozzolans are not themselves cementitious, but contain constituents that react with lime at ordinary temperatures in the presence of water to form stable hydraulic compounds.

Usage/Purpose

Argical M1000 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.

Shelf Life

Indefinite stored in dry condition.

Finish

Finely ground white powder.

Observations

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.
