SikaFiber-12

SikaFiber-12 is a polypropylene fiber used in concrete to enhance its properties, primarily for improving crack resistance and durability. It works by being uniformly distributed throughout the concrete mix, reinforcing the matrix and preventing the formation of cracks caused by shrinkage or external stresses.

How SikaFiber-12 Works:

• Crack Control: It helps control shrinkage cracks by providing internal reinforcement that resists cracking during the curing and drying process.
• Improved Durability: The fibers increase the concrete’s resistance to impact, abrasion, and freeze-thaw damage, making it more durable over time.
• Enhanced Toughness: The fibers improve the overall toughness and post-crack behavior of concrete, providing added strength even after the concrete has cracked.
• Easy Mixing: SikaFiber-12 is easy to mix into the concrete, improving its overall performance without affecting workability or setting time.
