Metacaulim HP ULTRA

Solução Ideal para Obras de Grande Porte

Metacaulim HP ULTRA is the ideal solution for major projects such as dams, ports and piers, sanitation plants, among others, commonly used in Brazil and worldwide. It consists of pure metakaolin, applied on concrete, cement slurry and mortar.

Main advantages of Metacaulim HP ULTRA

ícone Benefícios
Physical
Due to the small size of its particles, Metacaulim HP ULTRA fills the voids left by cement paste, reducing its porosity and also contributing to water retention, thus improving hydration of the cement and reducing cracks caused by capillarity and drying during the curing process.
Chemical
Metacaulim HP ULTRA reacts with the free lime (calcium hydroxide) present in cement paste, leading to, over time, composites much more chemically stable and more resistant such as C-S-H (hydrated calcium silicate) and C-A-S-H (hydrated calcium aluminum silicate).
