Anti - Crack AR Glass Fiber

Anti-Crack HD (High Dispersion) is an engineered AR-glass chopped strand designed for mixing in concrete and all hydraulic mortars.Anti-Crack HD fibers are typically used at low addition level to prevent cracking & improve the performance of concrete, flooring, renders or other special mortar mixes.They incorporate easily into mixes creating a multidimensional homogeneous network of reinforcement in the matrix.Anti-Crack?? HD fibres can be added at the central mixing plant to the wet concrete mix; or directly into the ready-mix truck.Quality Standards Certification:Fibres can be introduced directly in the ready mix plant or directly in the concrete truck. Recommended dosage is 600 g/m3 (1 lb/cum) of concrete to control plastic shrinkage cracking Anti-Crak HD fibres are packed in individual paper bags (water dispersible) or in plastic bags.Anti-Crak HD fibres should be stored away from heat and moisture, and in their original packaging.The best conditions are:Anti-Crak HD fibres do not protrude through the surface and require no additional finishing procedures.The reinforcement is incorporated in the concrete mass and is invisible on the finished surface.High dispersion (220 million filaments per kg, 100 million per lb)Excellent workabilityInvisible on the finished surfaceDoes not corrodeControl and prevention of cracking in fresh concreteOverall enhancement of durability and mechanical properties of concreteEffective at very low dosageHomogeneous mixSafe and easy to handleLoss on Ignition: 0.55% (ISO 1980: 1980)Moisture: 0.3% max (ISO 3344: 1977)Material: Alkali Resistant Glass*Specific Gravity: 2.68 g/cm3Electrical Conductivity: Very lowChemical Resistance: Very highModulus of elasticity: 72GPa – 10 x 106 psiTensile Strength: 1,700 MPa – 250 x 103 psiAnti-Crak HD fibres are part of Cem-FIL product range
