Concrete additive Argical®

for mortarplasticiser

Metakaolin is a pozzolanic, amorphous, silico-aluminate manufactured through the careful calcination of high quality kaolin. The pozzolanicity of metakaolin refers to its ability to react with calcium hydroxide and limestone, thus increasing strength and durability of concrete and mortars. In construction, Metakaolin is used in the manufacture of cements, concrete, and drymix mortars. Its synergy with calcium carbonate makes it perfectly suited for applications like tile adhesive, renders, technical mortars as well as high performance concrete. Manufactured through the calcination of kaolin to form an amorphous pozzolanic white mineral additive, our Argical-M range of metakaolins provides a broad range of benefits in concretes, lime mortars and plasters. The pozzolanic reactivity of metakaolin refers to its ability to react with calcium hydroxide in specialty binder based products. It is also used as an additive to substitute specialty binders. When used in concrete, Argical-M reduces porosity which allows for a reduction in the ‘cover’ of concrete needed to protect reinforcing bars from corrosion, making it ideal for road and marine structures exposed to corrosive salts. Argical-M also provides a higher cured compressive strength and speeds up curing and early strength development, in turn making it perfect for applications where high strength is required quickly such as airport aprons. Argical-M also reduces efflorescence by reducing the porosity of the concrete and reacting with lime salts before they reach the concrete surface.
