HYGC- high strength non-shrink grout

HYGC- high strength non-shrink grout Product Description: Zhejiang, Shanghai and Tianjin, Liaoning, Yunnan and Guangxi, Xinjiang and Guangdong Anhui Beijing Chongqing 湖南 湖北 Hebei, Henan and Ningxia Qinghai, Gansu and Shaanxi Tibet, Guizhou, Sichuan and Hainan Heilongjiang, Inner Mongolia and Shandong, Fujian 吉林 Shanxi, Jiangxi and Jiangsu GC series of high-strength cement-based non-shrink In high-grade special cement grout as a binding agent, selected high-strength composite aggregate, combined with bulking agents, plasticizing agent material dispositions. Is characterized by rapid strength development, fluidity big, without vibrating, micro-expansion, not contraction, strong bond. Non-toxic, harmless, non-aging, water quality and the surrounding environment pollution, since tightness is good, rust and other advantages. For the second pouring the foundation, steel structure anchored to the foot, reinforced concrete structure, bug fixes and other projects. Standard: "cement-based grout" JC / T986-2005. Features: 1, early strength and high strength: pouring one day strength can reach more than C20, 28 days strength can reach more than C60. 2, the flow is high: the scene after mixing with water is poured directly, without vibrating can fill all the gaps perfusion. 3, micro-expansion: Long-term use of non-shrink casting body, in order to ensure close contact between the equipment and infrastructure. 4. Peel: a solid combination of old and new interface to prevent peeling and cracking. 5, no corrosion: for steel, no rust steel and other hazards. 6, anti-oil seepage: 30 days immersed in the oil intensity than before immersion oil increased by 10%. 7. Durability: 2 million times fatigue test, 50 freeze-thaw cycle experiments no significant changes in intensity. 8, weather resistance: -40 ℃ ~ -60 ℃ long-term safety. Scope: 1, secondary grouting equipment installation; 2, steel column foundation installation; 3, various machinery electrical equipment without the installation of mobile filling horn; 4, column-based grouting rock bolt anchor grout; 5, the frame anchor structural joint access, bridge joints reinforcement; 6, grouting post-tensioned precast, prestressed bridge pouring; 7, the transformation of the concrete slab foundation walls and columns reinforcement and repair. Quality indicators: 1, specific surface area: more than 320 m2 / kg 2, Setting time initial setting: not less than 30min, final setting: not more than 6h Applicability: Applicable at temperatures above 20 ℃ environment, one day can be a release. GC early strength non-shrink grout (Ⅱ type) indicator: the applicability of the special project needs :() suitable for ambient temperatures below 0 ℃ and the need to use the next two hours in the case of the release. Construction Guide: 1, basic treatment: the base surface cleaning equipment, without gravel, laitance, dirt, grease and mold release agents and other debris. 24 hours before grouting equipment foundation surface should be fully wet, 1 hour before filling should dry water. 2, filling mode: the device according to the actual situation stands, select the appropriate grouting methods, since the material has good flow properties, under normal circumstances, with "filling weight method" can be, coming directly from the template mouth filling paste in, rely entirely on self-leveling slurry weight and fill the entire space infusion, perfusion if a very large area, the structure is particularly complex or small space and very far away, you can use "high funnel filling" or "pressure grouting method" grouting to ensure that the slurry can be sufficiently filled every corner. 3, formwork: level should be higher than in accordance with certain grouting methods and grouting construction drawing support provided template, template positioning device base surface of at least 50mm, the template must support set tight, secure, prevent loosening, leakage of plasma. 4, grout mixing: According to the product certificate recommended ratio of water to determine the amount of water, mixing water should be drinking water, the water temperature 5-40 ℃ appropriate, should the use of mechanical stirring, stirring time is generally 2-3 minutes, standard the ratio of water (mass ratio) of 13% -15%. Note: 1, mixing good slurry should be used within half an hour. 2, the slurry should be poured into the side, until the other side to overflow, in order to facilitate the discharge of air equipment base and concrete foundation, so filling full, it must not be grouted simultaneously from four sides. After filling start, it must be continuous, without interruption, and filling time should be as short as possible. 3, during the grouting process should not be vibrated, if necessary, can be pulled diversion bamboo strips. 4, longer equipment or track-based grout should be used in the construction segment. Each length 10m appropriate. 5, filling found during surface bleeding phenomenon can be a small amount of grout dry material dispenser, dry water. 6, in filling up the construction process before the release, you should avoid filling layer is subjected to vibration and impact. 7, filling in as running plasma phenomena occur, promptly. 8, in the thicker parts of use, 30% Mixed 5-10mm pisolite. Early strength due to temperature and have a significant impact on product setting time, at low or high temperatures, please explain the user in advance by our center to be adjusted by test technicians to meet project requirements. Unable to restore liquidity and avoid a slurry with water and then mixing again. Conservation: 1, after filling is complete within 30 minutes, immediately curing compound or covered with plastic film and stamped with rockwool and other conservation, or immediately after the final setting of the grout layer sprinkler moisture conservation. 2, winter construction, conservation measures should comply with the relevant provisions of "reinforced concrete construction acceptance norms" (GB50204) is. 3, curing and form removal time schedule at different temperatures: Packaging and storage: 1, compound bag packaging, 50 kg / bag. 2, moisture, shelf life of three months.
