Sika Plast® 520 BA

Sika Plast® 520 BA is a high-performance, air-entraining admixture designed to improve the workability, durability, and frost resistance of concrete. This admixture helps to introduce and stabilize controlled air voids within the concrete mix, enhancing its resistance to freeze-thaw cycles and improving its overall performance in harsh environments. Sika Plast® 520 BA is ideal for producing durable concrete with enhanced workability and increased resistance to cracking and scaling in freeze-thaw conditions, making it suitable for a variety of demanding construction applications.

Application:

• Ready-mix Concrete: Ideal for ready-mix plants, improving the workability, air entrainment, and durability of the concrete mix.
• Concrete for Cold Climates: Essential for producing concrete that needs to withstand freezing and thawing cycles, such as in cold-weather construction.
• Concrete for Exposed Aggregate Finishes: Helps in achieving a smooth, durable surface finish that can withstand the effects of freeze-thaw exposure.
• Precast Concrete: Improves the production of precast elements, particularly those exposed to extreme weather conditions, with better resistance to cracking and freeze-thaw damage.
• Mass Concrete: Ideal for mass concrete pours, as it helps with controlling the internal curing conditions and reduces the risk of thermal cracking.
• Pavements and Roads: Suitable for producing durable concrete for roads, pavements, and driveways exposed to freeze-thaw cycles and de-icing chemicals.
• Marine and Coastal Structures: Excellent for concrete exposed to harsh environments, including marine environments, where freeze-thaw durability is critical.
