Concrete, Screed and Mortar Reinforcement
Reinforcing highly alkaline matrixes such as Concrete Slabs requires special alkali-resistant glass fiber fabrics, known as AR glasses. Those glass fiber fabrics offer a high zirconium oxide (ZrO2) content of ≥ 16%.
Steel reinforcements require a concrete cover of at least 35mm to 40mm (1.38in to 1.58in), often not possible when thin construction is needed.
KAST AR-Glass mesh fabric on both sides of the panel provides the solution.
More often Screeds are being reinforced with textile reinforcement grids of 9mm (0.35in) and up to 40 mm (1.58in) mesh size. This reinforcement prevents early shrinkage cracks and replaces conventional steel reinforcements with vast advantages e.g. aspects in logistics, handling, safety and costs.
Nowadays, the Mortar applied to masonry joints is often layered thinner and reinforcing grids are used in growing numbers to increase the stability of the masonry.
