Tianjin high-strength non-shrink grout Direct

CGM high-strength non-shrink grout grout Introduction Cui 15,110,234,763 based on high-strength materials as aggregate, cement as a binding agent, combined with high flow, micro-expansion, anti-segregation and other substances from the preparation. It added a certain amount of water at the construction site can be used after mixing evenly. With reliable quality, lower costs and shorter cycle times and ease of use in terms of construction. Features have gravity, good fast hard, early strength, high strength, non-shrink, micro-expansion; non-toxic, harmless, anti-aging, water quality and the surrounding environment pollution, since tightness is good, rust, etc. High early strength and high strength after pouring more than 1-3 days 20-50Mpa strength, shorten the construction period. Artesian state scene just add water and stir, equipment foundations poured directly, mortar gravity, to ensure that no vibration, long distance grouting construction. Micro-expansion of long-term use of non-shrink casting body, to ensure that equipment and infrastructure in close contact, no shrinkage between the base and foundation, and appropriate expansion stress to ensure long-term safe operation of equipment. Anti-oil seepage in the oil soak for 30 days increased by more than 10 percent of its strength, molded, dense, impervious, base oil and adapt to the environment. Durability 2,000,000 times fatigue test, 50 freeze-thaw environment no significant change in strength tests. Good weather -40 ℃ ~ 600 ℃ long-term safe use of low alkali content of alkali corrosion strict control of raw materials for the alkali - aggregate reaction inhibit the requirements of the project. Applications grouting material mainly used for: fixed anchor bolts, runway repairs, nuclear power equipment, road and bridge engineering reinforcement, machine base, steel structure and foundation Huai mouth, based on secondary grouting equipment, plant buried steel, concrete structural reinforcement and renovation, old concrete structure crack control, electrical and mechanical equipment installation, rail and installation of steel structures, static piling engineering seal piles, thickening and leakage of water seepage wall structure repair, subsidence and filling various infrastructure projects all kinds of roads, bridges, tunnels, airports and other repair works. Grout Category 1, high-strength general-purpose grout, mainly used for: anchor bolts, cut buried steel, grout layer thickness of 30mm <δ <200mm equipment foundation secondary grouting, there is equipment foundation secondary grouting anti-oil requirements. 2, high-strength pisolite type reinforcing grout, mainly used for: grouting thickness ≥150mm of equipment foundation secondary grouting. Beams, plates, columns, foundation reinforcement and ground floor of the building (patch thickness ≥40mm), there is equipment foundation secondary grouting anti-oil requirements. 3, high-strength ultra-fine special grouting material, mainly used for: prestressed Duct Grouting, grouting thickness 10mm
