High-strength non-shrink grout material strength non-shrink grout is a cement-based dry mortar gravity-type micro-expansion, with early strength, high strength, self-flow and micro-expansion and other characteristics, suitable for secondary grouting equipment foundation, reinforcement of concrete structures , steel and anchor bolts anchoring works. Product Features 1. The early strength, high strength: 1-3 days compressive strength of up 30-50Mpa more than 24 hours after grouting to tighten the bolts to the boot test. 28-day strength up to 60Mpa or more. 2. With high gravity: the site mixing with water can be used, without vibrating can fill all the gaps. 3. The micro-expansion: no shrinkage after filling, to ensure close contact between the device and the foundation bolts. 4. Construction of winter: the minimum allowable temperature at -10 ℃ for outdoor construction. 5. Durability: This is inorganic cementing material life more than the life of the concrete foundation, the 2 million times of fatigue tests, grouting construction of one, process-based foundation surface should be cutting hair treatment. Clean the base surface, may not have gravel, floating pulp, floating dust, grease and mold release agents and other debris, 24 hours prior to grouting, the surface should be fully wet basis, one hour prior to grouting, remove stagnant water. Second, the formwork 1, according to construction plans grouting support provided template. Template-based, template and the template between water and mud seams, seam sealing tape, etc., to the extent that the overall template watertight. 2, the end of the template and equipment sit around a horizontal distance should be controlled at about 100mm, in order to facilitate grouting construction. 3, the top of the template should be higher elevation equipment sit bottom surface of 50mm. 4, filling in as running plasma phenomena occur, promptly. Third, the grout preparation 1, in general, according to the GM standard reinforced 13-14% of water mixing, pisolite reinforced by 9-10% standard add water and stir. 2, high-strength non-shrink grout mixing can use mechanical or manual mixing. Recommended compulsory mixer with mechanical stirrer, can ensure adequate mixing evenly, stirring time 3-5 minutes. Artificial mixing time in less than five minutes to complete. After stirring the grout with parked timetable growth, reduce its liquidity, it should be used within 40 minutes. Prohibited in high-strength non-shrink grout compound mixed with any additives. Fourth, grouting construction method, longer equipment or track basis, should be segmented construction. 2, after filling begin, it must be a continuous, without interruption, and filling time as short as possible. V. conservation 1, grouting is completed, after the initial setting grout should immediately stamped straw bags or rockwool, and kept moist. 2, winter construction, grout, mixing water and conservation measures should be consistent with the current "Concrete Structures Construction Quality Acceptance" (GB50204) the relevant provisions. 3, 24-36 hours after grouting not subject to vibration, to prevent damage to the outstanding hard grout layer. Packing, storage 1. Packing: 50kg / bag, stored in a dry place and prevent direct sunlight. 2. The shelf life of three months, before being used beyond the shelf life should recheck qualified. 3.
