Architectural SCC elements, exposed finish panels, and high‑strength floors.

03

Ocelové vlákno

Mikro výztuž pro vysokoupevnostní SCC

LANDU Steel Fiber provides integral reinforcement for Self‑Compacting Concrete where toughness and crack resistance are key. The fibers evenly distribute stress, enhancing post‑crack load capacity and structural ductility.

💪

Technické výhody

  • Improves impact resistance and flexural performance
  • Reduces crack width and propagation in SCC
  • Maintains structural integrity under dynamic loads
🏗️
Ideal for:

Industrial SCC floors, tunnels, bridge decks, and precast load‑bearing components.

Polypropylenové (PP) vlákno

Ovládání smrštění a stabilita povrchu

LANDU PP Fiber enhances surface cohesion in fresh SCC, minimizing plastic shrinkage cracks during curing. It ensures dimensional stability and smoother finishing quality for both precast and in‑situ SCC applications.

💪

Technické výhody

  • Controls early‑age cracking under rapid drying
  • Improves flexural toughness and internal cohesion
  • Easily dispersed and compatible with PCE based SCC mixtures
🏗️
Ideal for:

Architectural surfaces, foundation slabs, and decorative SCC applications.

CCCW – Krystalický kapilární hydroizolační přísada

Integrovaná ochrana pro dlouhou životnost samonivelačního betonu

LANDU CCCW provides internal waterproofing and strength improvement simultaneously.

It reacts with hydration products to form insoluble crystalline structures that block pores and micro‑cracks, significantly enhancing the durability of Self‑Compacting Concrete in aggressive or wet conditions.

💪

Technické výhody

  • Creates permanent internal waterproof barriers in SCC
  • Increases compressive strength and chloride resistance
