High strength non-shrink grout material Product Code: of HGM / CGM Ruihua: 15,838,079,336 Model: HGM-1/CGM-1 HGM-2/CGM-2 HGM-3/CGM-3 HGM-4/CGM-4 Product Description: early strength high strength, resistance to segregation performance, green, micro-expansion, gravity, winter construction, durability, resistance to cracking capacity Function Description: Uses: △ device basis of secondary grouting △ anchor bolts anchoring and reinforced concrete buried planted △ structural reinforcement and repair packaging specifications: 50kg / bag ★ Features: ☆ early strength, high strength :1-3 day compressive strength of 30-75Mpa. ☆ Segregation capability: high strength non-shrink grout to overcome segregation phenomenon due to the amount of water above normal field use. ☆ Green: do not contain BTEX, halogenated hydrocarbons, formaldehyde, heavy metals and other ingredients, non-toxic, tasteless, non-polluting, non-flammable non-explosive, according to general cargo transportation. ☆ micro-expansion: to ensure close contact between the equipment and basic, secondary grouting contraction. ☆ gravity high: fill all voids, to meet secondary grouting equipment requirements ☆ winter construction: to allow for outdoor construction in a temperature of -10 ℃. ☆ durability: 50 freeze-thaw cycle experiments no significant change in strength after a million times fatigue test. 30 days immersed in the oil intensity has improved significantly. The ☆ anti-cracking ability: field use, due to the uncertainty of the amount of water added, the uncertainty of the ambient temperature and the conservation conditions, and other factors in the crack phenomenon. ★ 5 uses a device basis of secondary grouting 2, applies to the machine base, anchor bolts anchor and foundation grouting reinforced planted buried and equipment, flat slab column base of the building, floor and road reinforcement, repaired or reinforced, 3 reinforcement and repair of concrete structures 4, subway tunnels underground engineering inverse play the embedded solid construction joints. 5, steel structures, (rail, steel frame steel columns, etc.) the secondary grouting the basis of a fixed connection. ★ physical properties of the project model compressive strength (Mpa) vertical expansion rate (%) fluidity (mm) slump (mm) the reinforced adhesive strength (MPa) 1d3d28d round steel rebar the HGM General ruggedized 20-3540-5555 -75 ≥ .02270 - ≥ 6 ≥ 13 the HGM pisolite reinforcement type 20-3540-5555-75 ≥ 0.02 - 270 ≥ 6 ≥ 13 HGM ultrafine rugged 15-3025-4555-65 ≥ 0.02240 - ≥ 6 ≥ 13 ---- 7h1d28d? ---------- HGM early strength rugged ≥ 1520-4555-75 ≥ 0.02220 ------ Note: 1, compressive strength press: "GB177-85 cement mortar strength test method "; expansion rate:" GB119-88 concrete admixtures application of technical specifications ". Grouting thickness the δ ≥ 150mm, the choice of HGM-1 or HGM-2; grouting thickness 30mm <δ <150mm chosen HGM-1 or HGM-2; grouting layer thickness δ ≤ 30mm, the choice of HGM-1 or HGM-3 type; pavement quickly repair choice the HGM-4 type. ★ grouting material preparation, the HGM grouting material mixing, the recommended amount of water added in the amount of water should be provided with the goods on the certificate, stir, can be used. For anchor bolts anchoring and planted buried reinforced, water consumption in accordance with the actual situation of the project be reduced appropriately. Mixing water should be drinking water, other water sources, shall comply with the provisions of the existing concrete mixing water standard "(JGJ63),. HGM grouting material mixing can be mechanical stirring or manual mixing. Recommend the use of a mechanical stirrer, stirring time is generally 1-2 minutes (non-hand drill type agitator). Add 2/3 of the water consumption using artificial stirring mixing of two minutes, and subsequently adding the remaining water and stir until evenly. 3, stirring location should be as close as possible to the grouting material construction sites, the distance should not be too long. 4, each time stirring amount would depend on how much usage, to ensure that the material will be used up in less than 40 minutes. 5, when the winter construction, HGM grouting materials and mixing water should be consistent with the existing reinforced concrete construction and acceptance of norms "(GB50204) the relevant provisions. 6, the on-site use, is strictly prohibited in HGM grouting compound mixed with any admixture Mixed material. ★ demolition of the relationship between the film and curing time and ambient temperature table daily minimum temperature () form removal time (h) the conservation time (d) -10 09 624 0 to 57.21 thousand 5 15487 ≥ 15247 ★ reference to the amount of: the reference to the amount of 2.28 to 2.4 t / m 3 as the basis for calculating the actual usage. ★ Packing, storage, grout 50kg / bag, stored in a cool, dry and well ventilated place to prevent direct sunlight. 2, the shelf life of three months beyond the shelf life should recheck qualified before use.
