Adding to cart… The item has been added

Argical M1000 is an off-white pozzolan with moderate strength properties. The neutral colour of this Metakaolin Pozzolan, helps to retain the colour of the mortar that is is added to.

Pozzolans are materials that contain high silica and/or alumina content.  They react chemically when mixed with Lime (Calcium Hydroxide) to form a compound with cementitious properties.

When added to putty lime or quicklime mortars, pozzolans will create an initial ‘set’ in the mortar, giving it hardness in the early stages of calcification and will increase the overall strength of the mortar when cured.
