Moderate/Aggressive environmental class

Moderate/Aggressive environmental class
 
Moderate concrete:
Used in humid environments, where there is no risk of the effects of frost action in combination with water-logging. Consistency: Typical choice is slump in the range 40 to 200 mm. Hearting concrete should be vibrated mechanically until the encapsulated air is expelled.

Application areas
Hearting concrete in the Moderate environmental class is used primarily for construction. For example, foundations partially above ground, exterior walls, facades and columns, workshop and garage floors on the ground, etc.

Aggressive concrete:
Used in humid environments, where there can be a lot of moisture with the risk of water-logging in combination with the effects of frost.
 
Application areas: 
Hearting concrete in the Aggressive environment class is used primarily for construction. For example, exterior paving, exterior basement stairway/shaft, basement walls partially above ground, channels in groundwater, retaining walls, etc.

Extra aggressive concrete:
Used in humid environments, where there are large amounts of alkalis and/or chlorides added to or stored on the concrete surface.

Application areas: 
Hearing concrete in the Extra aggressive environmental class is used primarily for swimming pools, pools, bridge pillars, bridges, marine facilities, etc.
