GRT a high-strength non-shrink grout, product performance: Zhang Gong Tel 18501271576 GRT series grouting material widely used in plant construction, mechanical equipment, electrical equipment installation, maintenance and repair works, port terminal rail mounting grouting works, as well as all types of concrete structures reinforcement, waterproof plugging and highway repair. GRT series grout has been successfully applied to a number of large-scale key projects, such as the National Sports Center, Bird's Nest, Water Cube project; BMW plant in Shenyang Engineering; Liaoning Hongyanhe Nuclear Power Engineering; Dalian new sports center project; Dalian high-speed rail projects, such as North Station . Involved in metallurgy, paper, power, ports, civil, chemical and other industries, with its excellent quality praised by users, has played a strong influence in more and more areas. Second, the product features a good fluidity: no bleeding, with a self-leveling effect, fill all gaps. 2, early strength Strength: 24 hours up to 30% of the final compressive strength of more than 3 days 60% l-3 is mounted within the device. 3, no shrinkage, high bond strength: a micro-expansion, and reinforced with good bond strength. Ensure that the anchor bolts and base (steel) base and a solid combination of new and old concrete. 4, good durability: the case of inorganic silicate materials perfusion, no aging, no corrosion of steel, resistant to oil. The use of methods Zhang Gong Tel 18501271576 preparation: cleaning the surface, may not have gravel, floating pulp, oil and other debris. 24h should be fully wet the surface before grouting. There shall be no standing water prior to filling. Formwork: Template not leak slurry, grout on top of the template above the surface about 50mm. Mixing: the amount of water added to the mixing bucket, and then feed into the barrel stirring, mixing time starts vote expected stir 3-5 minutes at the end of control when mixing blades shall be raised to the surface from the top of the slurry to avoid into the air. Perfusion: overflow from the side of the other side until the grout, when necessary, can be inserted bamboo pound. Maintenance: 3-5 hours after grouting should wipe the surface layer of grout pressure light, after that moist cloth or straw covering sprinkler maintenance, water conservation period of not less than seven days, watering frequency to keep the grout in a wet state standards. Fifth, the use of: 1. Large equipment and precision equipment anchor bolt and base. 2. Steel (such as rail, steel, steel columns, etc.) and basic solid pick perfusion. 3. Post-tensioned reinforced grouting. 4. Beams, columns reinforcement. 5. Subways, tunnels, underground works against the play construction joints mounted. 6, thickening and leakage of water seepage wall structure repair. Sixth, packaging and storage using moisture-proof packaging, net weight 25kg / bag, shelf life of 12 months; shall be stored in a dry and ventilated room, pay attention to moisture, use as soon as possible.
