Special grout manufacturers, oil cooperation unit, Jinan Iron and Steel suppliers, Extension of the grout has a strong professional business innovation capability and superior products. Where the grout, Latex waterproof mortar, mortar, self-leveling cement scientific formula, the interface agent products to meet international technical level, enjoys a high reputation. TD-B4 antifreeze a high-strength grout, use a grout antifreeze, secondary grouting equipment installation ?? 2, 3 steel column base installation, various machines electrical equipment without the installation of mobile filling four horns, anchor bolts Column 5 based grouting rock foundation grouting, anchor frame joints connected, bridge joint reinforcement 6, the transformation of concrete beam column combined foundation wall reinforcement and repair two, antifreeze grout technical characteristics, low construction: ambient temperature 0 ~ -20 ℃ normal construction 2, early strength and high strength: to run the equipment installed 3 days after production, continued to improve: Standard strength pouring normal body temperature will rise after 4, gravity-free shock, micro-expansion. 5, no rust, anti-oil seepage. 6, Durability: 2 million times of fatigue experiments, 100 freeze-thaw cycle experiments no significant changes in intensity. Third, the Extension of antifreeze grout fluidity test model performance indicators (mm) Compressive Strength (Mpa) at -15 ℃ ambient vertical expansion ratio (%) of reinforced adhesive strength Mpa other initial 30min -1d -3d -7d + 28d 56d 3h 24h and 3h difference TD-B4 ≥300 ≥290 ≥15 ≥30 60 ≥75 ≥0.1 0.05 ≥6 no bleeding, no corrosion of steel four, antifreeze early strength grout packaging storage 1, antifreeze grouting material for plastic bags, packaging specifications for the 50 kg / bag. 2, the product unopened, should be in a dry, cool, ventilated place to store packaging. Under normal conditions of storage and transportation, shelf life of 12 months. NOTE: For details, see the company's website www.gjl369.com
