Changchun grouting material / Changchun grouting material Changchun grouting material / Changchun grouting material Changchun grouting material / Changchun the grouting material Changchun grouting material / Changchun the grouting material Changchun grouting material / Changchun the grouting material Changchun grouting material / Changchun Changchun grouting material distributor grouting material, Changchun grouting expected total wholesale, grouting material manufacturers call 18244030486 high strength non-shrink grout manual Product Features: 1, early strength, high strength-day compressive strength ≥ 20Mpa; 3-day compressive strength ≥ 30Mpa; 28-day compressive strength ≥ 55Mpa. 2, micro-expansion to ensure that equipment and basic close contact between the secondary grouting contraction. 3, artesian high fill all voids, meet secondary grouting equipment requirements, resistance to segregation to overcome segregation phenomenon due to the amount of water above normal field use. 5, anti-crack crack phenomenon 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. 6 million on the fatigue test durability by 50 freeze-thaw cycles experimental intensity did not change. 30 days immersed in the oil intensity has improved significantly. 7, winter construction allows for outdoor construction in a temperature of -10 ℃. Uses: 1, used for the equipment the basis of secondary grouting. 2 for anchor bolts anchoring and reinforced planted buried. 3 for reinforced concrete structure and repair. Product selection, the grout layer thickness δ ≥ 150mm, selection of HGM-1 or HGM-2; 2, grout thickness 30mm <δ <150mm, the choice of HGM-1 or HGM-2; 3, the grout layer thickness δ ≤ 30mm , the selection of HGM-1 or type HGM-3; 4 rapid, road repair, the choice of the type of HGM-4. Prepare a pre-construction, machinery Mixing: Concrete Mixing shaking machine or mortar agitation machine; manual mixing: mixing tank and shovel; 3 buckets certain; 4, platform scale certain; 5, launder; 6 high funnel grouting pipe and pipe fittings; 7, grouting boosters; 8, template (steel, wood mold); 9, straw bags, rockwool; 10, cotton yarn, tape; grouting first step: basic processing infrastructure surface chiseling processing. Clean the basis of the surface, not gravel, laitance, floating dust, grease and mold release agents and other debris. 24 hours before grouting the basis of the surface should be fully wet, one hour prior to grouting, remove stagnant water. Step 2: branch touch a template by grouting Figure branch located. Sealing grout seams between the template based on template template, tape, reached the extent of overall template watertight. 2, the horizontal distance of the template and equipment around the base should be controlled at about 100mm facilitate grouting. 3, elevation of the top of the template should be higher than on the surface of the equipment chassis 50mm. 4, grouting, such as running plasma phenomena, should be timely treatment. The third step: preparation of grouting material, generally 13-14% of the standard, common ruggedized add water and stir, add water and stir beans stone rugged standard of 9-10%. 2, 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 2 minutes, and subsequently adding the remaining water and stir until evenly. 3, each time stirring amount would depend on how much usage, to ensure that the material will be used up in less than 40 minutes. 4, the on-site use, is strictly prohibited in HGM grouting compound mixed with any admixture Mixed material. Step 4: second grouting grouting method shall meet the following requirements. Secondary grouting should be on one side or on both sides of the adjacent multi-grouting, until other side overflow exhaust facilitate the grouting process. Not from the four sides of the grouting. After the start of the grouting must be carried out continuously without interruption. The grouting time as short as possible. The grouting process non vibrators. The HGM grouting material available when necessary the grouting boosters along the bottom of the grout layer to promote, from the grout layer, the upper part to promote, in order to ensure the homogeneity of the grout layer is strictly prohibited. 4, after the equipment foundation grouting, along the edge of the machine should be 3-6 hours after the grout out cut a 45-degree angle (see below) to prevent the free end of the cracks, such as not trimming after grouting 6 hours after the grout layer surface with a spatula pressure light. 5, when the grout layer thickness exceeds 150mm by pisolite rugged high-strength non-shrink grout. 6, when the large amount of equipment foundation grouting, grouting material the pisolite rugged stirring should be used mechanical agitation to ensure grouting. Step 5: conservation, grouting after 30 minutes should be immediately stamped with wet grass cover or rockwool, and keep it moist. 2, winter construction, conservation measures should meet the relevant provisions of the <> (GB50204). 3, after the equipment foundation grouting, if any to remove part of the can after 3-6 hours after grouting is completed prior to the hardening of the grout layer lightly with a spatula or shovel tool to eradicate. Not transmit the vibrations of the machine is in operation to equipment foundations, should be down to 24 - 36 hours after the second grouting, grouting to avoid damage to the outstanding hard layer. Packing, storage, packaging specifications: 25kg / bag, stored in a cool, dry and well ventilated place and prevent direct sunlight. 2, the shelf life of six months beyond the shelf life should recheck qualified before use. 3 does 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.
