The Low Temperature Resistant Concrete It is specially designed to withstand frost heave and freezing-thawing cycles, which cause cracks and disintegration in common concrete.
When water freezes inside the pores of concrete, it expands and creates internal stresses that destroy it. Our special formulations prevent this deterioration through:
- Additional Air Conditioners:They create billions of tiny air bubbles that act as "expansion tanks" for the ice, preventing cracking.
- Coagulation Accelerators:They allow the concrete to quickly gain the required strength before the temperature drops to critical levels.
- Low Absorbency:The dense structure limits the entry of moisture, and therefore the amount of water that can freeze inside.
Ideal for: Mountainous areas, cold rooms and outdoor floors exposed to extreme cold.
The result: Constructions that remain solid and safe, without peeling or cracking, even at the lowest temperatures.
Exhibition Categories:
-
- C30/37 XF1: It is applied to exterior works in frosty areas, such as sidewalks, retaining walls and floors, where water freezes and thaws repeatedly, but de-icing salts are not used. The XF1 category (now called XΔ1) requires a specific resistance of the concrete to freeze-thaw cycles (usually with the use of an air-entraining agent) to avoid surface spalling, while the C30/37 strength meets increased static requirements.
- C25/30 XF2: It is applied to exterior projects exposed to frost where anti-icing salts are used, such as sidewalks, curbs and road construction elements. Its composition includes special additives (aerating agents) that create tiny air bubbles in its mass, allowing water to expand when it freezes without crumbling the concrete, while at the same time its strength protects the reinforcement from the action of chemicals.
- C25/30 XF3: It is applied to horizontal surfaces of road works (bridge decks, ramps, floors) in areas with severe frost, where large quantities of anti-freezing salts are used and the concrete is exposed to alternating wetting-drying. Its composition requires a high content of air-entraining agent to withstand intensive freeze-thaw cycles, while protecting the reinforcement from chloride corrosion.
- C30/37 XF4: It is applied to horizontal surfaces of road works, bridges and industrial floors in areas with extreme frost, where the concrete is in constant contact with water and large quantities of anti-freezing salts. The very high strength C30/37 and the maximum durability class XF4 ensure the absolute protection of the concrete mass and reinforcement from the combined and destructive action of freeze-thaw cycles and chlorides.
