Construction above the ambient temperature can be -10 ℃. The product construction convenient, low-carbon environment, quality and cheap, is the preferred home improvement building materials, construction, factories and so on. Use grout:? Equipment foundation, anchor bolts, steel pillar foot plate, bridge rubber bearing basin, bridge expansion joints, the wind farm stand prestressed tension anchors, rail spikes and all kinds of structures. ? Grouting: beams, columns and shear wall thickening of the cross-section increases. ? Filling Filling: concrete, holes and other grouting filling, sealing. ? Emergency repair and construction works have low requirements. Technical parameters fluidity compressive expansion retention value of the initial value of 30 minutes one day compressive strength of three days compressive strength compressive strength difference 28 days 3 hours 24 hours and three hours expanded value ≥300mm ≥270mm ≥20Mpa ≥40Mpa ≥ 65Mpa 0.1 ~ 3.5 0.02 ~ 0.5 Note: A, according to the standard GB50448-2008, B, the operating time ≥40 minutes Construction Primary treatment: the base surface cleaning equipment, without gravel, floating pulp, floating dust, oil and rubber mold agent and other debris, 24 hours prior to grouting, basic equipment should be fully wet the surface and remove stagnant water. Support provided templates: Templates and basic. Seams to be closed between the template and the template; horizontal distance around the base template and equipment should be controlled at about 100mm; the top of the template should be 50mm above the surface of the base on the device parameters calculated as follows: 12 to 14% water, the amount of material 2280 ~ 240kg / m3. Material Preparation: Recommended by mechanical mixing method, mixing time is generally 1 to 2 minutes (do not touch the drill mixer). The amount of time mixing depending on use and how much should be to ensure that time spent in the operational. Note: Do not mixed with any additives, admixtures, special circumstances, please contact the manufacturers technical department. Grouting method: equipment foundation secondary grouting material, grouting methods should be selected according to the actual situation. Grouting Construction: from one side to the other side of irrigation, equipment foundation secondary grouting should be on one side or both sides of the adjacent multi-grouting, until the other side to overflow, may not be grouted simultaneously from four sides. Starting after grouting must be continuous, without interruption, and filling time as short as possible. Note: (1) When the grout from the ≥1.5m, the use of high-filling funnel method, starting from the base of the equipment and the central or side grout. Longer equipment or track-based grouting method should be used to jump warehouse section construction, and each length ≤5m. (2) Do not vibrated during the grouting process to avoid the inclusion of air trapping, filling the bottom of the booster can be used to promote the grout along the grout layer, it is prohibited from filling layer, the upper push to ensure homogeneity of the grout layer. (3) equipment foundation grouting is completed for 3 to 6 hours should be cut 45 ℃ angled outward edge of the machine, to prevent the free end of the cracks. May not be rotating machine vibration transmitted to the device, based grout should be shut down after 24 to 36 hours, so as not to damage the outstanding hard grout layer. Conservation: (1) immediately stamped grout should be finished within 30 minutes of wet straws or rockwool, and kept moist. (2) When the temperature is higher than -10 ℃, take a layer of plastic film, two alternatives to straw or other covering conservation; when the temperature is below -10 ℃, should take winter construction measures, such as: Cattle Act, Comprehensive poised law. (3) removal time, curing time and temperature relationship: the daily minimum temperature (℃) removal time (h) curing time (h) -10 ~ 0 ≥96 ≥10 0 ~ 5 ≥75 ≥10 5 ~ 15 ≥ 48 ≥7 ≥15 ≥24 ≥7 Packaging storage: 25Kg / bag, stored in a dry, airy environment, water, moisture, the shelf life of three months. High-strength non-shrink grout is a 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. Having gravity is good, fast hard, early strength, high strength, non-shrink, micro-expansion; no aging, water quality and the surrounding environment pollution, since tightness is good, rust, etc. With reliable quality, lower costs and shorter cycle times and ease of use in terms of construction. Fundamentally change the base of the equipment the forces, so that uniform load to bear all the equipment to meet all kinds of machinery, electrical equipment (heavy equipment, high-precision grinding) the installation requirements are not ideal grout pad installation times. Grouting material uses high-strength non-shrink grout material mainly used for: secondary grout anchor bolts, runway repairs, nuclear power equipment, road and bridge engineering reinforcement, machine base, steel structure and foundation Huai mouth, equipment foundation, planted buried reinforced concrete structure reinforcement and renovation, old concrete structure crack control, electrical and mechanical equipment installation, rail and installation of steel structures, static piling engineering seal pile wall thickening and leakage of water seepage structure and repair, various infrastructure projects The collapse of filling and a variety of repair projects. Grout Category 1, mainly used for: anchor bolts, cut buried steel, grout layer thickness 30mm <δ
