Argical-M 1000

Argical-M 1000 is a reactive pozzolan (a powdered additive made from burnt clay) used to achieve a hydraulic set in traditional lime putty mortars and plasters.

Pozzolans are helpful when applying lime putty mixes in damp, frost prone or exposed locations. The addition of Argical to lime putty mixes will increase compressive strength which helps to offer additional protection during the carbonation period.

Traditionally, volcanic ash, brick dust and other forms of burnt clays were used as additives in lime putty mixes and today this is refined in the form of Argical-M 1000. The term ‘pozzolan’ originates from the Italian town of Pozzuoli where volcanic ash was added during Roman times.

We recommend adding a pozzolan between 5% – 10% by volume depending on the time of year, exposure and use.
