Ready-to-use mixtures of concrete and sand concrete

For the production of concrete and sand concrete plastifiers, hardening accelerators, air entraining agent, during summer time curing retarder are used. During the cold season, we produce all kinds of mixtures with hardening accelerator.

Exposure class:

Class designation Description of the environment Informative examples where exposure classes may occur
No risk of corrosion or attack
XO For concrete without reinforcement or embedded metal: all exposures except where there is freeze/thaw, abrasion or chemical attack. For concrete with reinforcement or embedded metal: very dry. Concrete inside buildings with very low air humidity.
Corrosion induced by carbonation
XC 1 Dry or permanently wet Concrete inside buildings with low air humidity. Concrete surfaces permanently submerged in water.
XC 2 Wet, rarely dry Concrete surfaces subject to long-term water contact. Many foundations.
XC 3 Moderate humidity Concrete inside buildings with moderate or high air humidity. External concrete, sheltered from rain.
XC4 Cyclic wet and dry Concrete surfaces subject to water contact, not within exposure class XC2.
Corrosion induced by chlorides other than from seawater
XD1 Moderate humidity Concrete surfaces exposed to airborne chlorides
XD2 Wet, rarely dry Swimming pools Concrete exposed to industrial waters containing chlorides
XD3 Cyclic wet and dry Parts of bridges exposed to spray containing chlorides Pavements, sidewalks Car park slabs
Corrosion induced by chlorides from seawater

XS2 Permanently submerged Parts of marine structures
XS3 Tidal, splash, and spray zones Parts of marine structures
Freeze/thaw attack with or without salt
XF 1 Moderate water saturation without de-icing agent Vertical concrete surfaces exposed to rain and freezing.
XF 2 Moderate water saturation with de-icing agent Vertical concrete surfaces of road structures exposed to freezing and airborne de-icing agents.
XF3 High water saturation without de-icing agent Horizontal concrete surfaces exposed to rain and freezing
XF4 High water saturation with de-icing agent or sea water Road and bridge decks exposed to de-icing agents Concrete surfaces exposed to direct spray containing de-icing agents and freezing Splash zone of marine structures exposed to freezing
Chemical attack
XA1 Slightly aggressive chemical environment
XA2 Moderately aggressive chemical environment
XA3 Highly aggressive chemical environment

Chloride content in concrete mixture ~ 0.2 % of cement weight
