Sulfaluk

Sulphate resistant cement / for concreting at extremely high temperatures.
Specifically adapted for construction where groundwater and humid environment have a high sulphate content and for making a concrete at extremely high temperatures.

Description

Sulphate resistant cement with low heat of hydration, with a blast-furnace slag content of 66%-80%, and 20%-34% of clinker, including a natural gypsum as regulating binding agent. The certificate of conformity to specifications: HRN EN197-1 i HRN EN197-2, BAS EN 197-1, BAS EN 197-2.

Benefits and Characteristics

SUITABLE FOR CONCRETING IN WARMER ENVIRONMENT
Suitable for concreting in low heat environment with reduced risk of so called “burnt concrete” due to the lower heat of hydration and reduced tendency of strengthening and formation of cracks in concrete,
HIGH CONCRETE RESISTANCE
High concrete resistance in aggressive sulphate-rich environment due to the high content of blast furnace slag,
INCREASED RESISTANCE
Increased resistance on influence of pure and aggressive water environment,
POSSIBLE THERMAL TREATMENT
Possible thermal treatment in initial phase,
MODERATE BINDING OF THE CEMENT
Moderate binding enables longer manipulation during the work with concrete

Concretes in contact with soil exposed to chemically aggressive environment (cesspools, foundations, floors and walls on farms, chimneys, fire places and similar);
Concrete structures of large section and volume (large blocks, large base plates, dam body etc.);
For concrete work at extremely high temperatures and wind (above 25 ºC).
