Li Tak series of special cement grout is used as a binder, selected high-strength materials as aggregate, combined with high flow, micro-expansion, anti-segregation and other substances dispositions. The product has a gravity is good, fast and hard, early strength, high strength, non-shrink, micro-expansion; non-toxic, harmless, non-aging, water quality and the surrounding environment pollution, since the density is good, rust and other characteristics. With reliable quality, reduce costs and shorten the duration and ease of use in the construction areas. Fundamentally change the base of the forces on the device, so that uniform load to bear all the equipment to meet all kinds of machinery, electrical equipment (heavy equipment, high-precision grinding) installation requirements, is not ideal grout pad installation times. Features: 1, early strength, high strength: more than 1-3 days compressive strength 30-50Mpa, equipment installed to run the day after the production. 2, gravity state: the scene just after mixing with water, poured into the device directly to the foundation, without vibrating device can fill all the gaps basis. 3, micro-expansion: to ensure close contact between the equipment and infrastructure, pouring body no shrinkage, to ensure long-term safe operation of equipment. 4, non-corrosive: for steel, steel and other non-hazardous 5 rust, anti-oil seepage: 30 days immersed in the oil intensity than before the immersion oil increased by more than 10% 6 Durability: 2 million times fatigue test, 50 freeze-thaw no significant changes in the intensity of the test cycle 7, good weather resistance: -40 ℃ -600 ℃ long-term safe use of 8, the anti-segregation: the old and new interface with a solid Scope: 1, 2 secondary grouting equipment installation, steel column base install grout 3 , various machines installed electrical equipment without horns flow grout 4, anchor bolts, column-based grout, grout batholith 5, anchor frame joints connect the bridge reinforcement grout joints 6, post-tensioned precast grouting, prestressed bridge pouring 7, the transformation of concrete beams, slabs, columns, walls and foundation together and repair grout reinforcement amount of packaging and storage 1, the reference amount: 2.28 ~ 2.4 tons / cubic meter, gray powder, brown paper bag, net weight 50kg // bag. 2, shall be stored in a dry and ventilated room, to prevent direct sunlight to prevent moisture.
