TRANSCRIPT
Metakaolins... . . .produced by České lupkové závody, a.s. are obtained through controlled thermal processes and grain size adjustments of clay stones and oating kaolin clays with stable chemical composition. It is a highly active pozzolan* on base of metakaolinite.
The application possibilities.... . .of our metakaolins, which are produced trough a unique and longtime veri ed method, complying with ISO 9001:2009 certi cations
• Additive to concrete (shotcrete, high strength concrete, lightweight concrete)
• Mortar mixtures • Insulations systems • Fire protection systems• Replacement of microsilica in selected applications • Production of geopolymers• Use by construction of swimming pools and natural
small lakes (including salt water)• Waterproof coatings for aggressive environments • Ingredient in sealants • Filler for composite materials and plastic insulating
materials
…advanced Technology
* The name “pozzolan” comes from the town of Pozzuoli, near Naples. Natural pozzolans are the rocks of volcanic origin such as tuff. Arti cial pozzolans are latent hydraulically-active matters, whose binding properties are initiated by mixing of milled pozzolan with an alkaline additive.
Benefits:• strength increase• reduction of water absorption • increased frost resistance• increased thermal resistance• porosity reduction• increased chemical resistance • reduction of concrete ef orescence forming• increased salt resistance • reduced alkali-silica reaction
