Solidification time can be adjusted number of incorporation, the use of safe and convenient. 3. Use: mainly used in mine roadway, railway tunnels, culverts, water and underground construction shotcrete construction projects and repair works, to speed up the progress of the project to improve the efficiency and quality of the project. 4, using the methods and precautions: a, before use of cement and other construction materials are used aptitude test to determine the optimum amount. Reference incorporation of 3-6% by mass of cement, water-cement ratio of 1: 0.4-0.45, sand lime ratio of 1: 2-3. b, construction, water-cement ratio should be strictly controlled, such as water-cement ratio is too large, it will prolong clotting time, affect the results. c, the incorporation of this product should be deducted from the amount of the corresponding neat. d, after the construction of the concrete to strengthen the splashing water conservation, improve strength. 5, the main technical performance requirements and test results: number of pilot projects "standards" test results 1, the chloride ion content /% ≤ 0.1 0 2, the total amount of alkali /% ≤15 0 3, PH value of 11 ± 1 4 4 solid content /% ≥40 56 5, density / g / cm3 1.41 ± 0.2 1.392 6, initial setting time / min / s ≤3: 00 1-2 7, final setting time / min / s ≤ 8:00 4 -7 8, 1d compressive strength / mpa ≥ 7.0 12 9, 28d compressive strength / mpa ≥75 ≥95 10, concrete PH value 9-10 1, PH value: PH = 4 2, low dosage, usually cement amount of 3-6%, and replace the same amount of water. The actual content should be based cement variety, grade and construction temperature After adjusting OK. 3, fast setting time, the initial setting 1.5-2min, the final setting of 6.5-7 min. 4, good adhesion, the thickness of a spray. 5, rebound low, generally 0.5 to 5%. 6. Face less dust. 7 and 28 day strength is not mixed with more than 90%. 8, impervious waterproofing effect, up to more than P12. 9, can reduce alkali corrosion of concrete structures in vivo, improve the quality of concrete strength agents ejection durability. Second, the adaptation range alkali accelerator: This product is suitable for mine construction, mining, mine engineering, cavern engineering, road and rail, traffic engineering, spray anchor support concrete, construction, defense, water and other underground injection project concrete construction and plugging, ground cement concrete construction and concrete emergency rescue and repair reinforcement. Third, the use of methods and precautions 1, must be used for the construction of cement and adaptability with this agent do the best content test before using this product. 2, for dry and wet spray spray technology, this product can be used. When using the gun should be in the vicinity of the jet at the outlet of adding a liquid accelerator, the concrete should be deducted from the amount of water water accelerator introduced. 3, the incorporation of the accelerator can be meter or meter precision control. 4, the product should be stirred bucket even after opening, if not finish the first use, the lid should be covered to prevent affect the results. 5, when the ejection construction using PO32.5 (42.5) over the fresh cement. You may not use expired or damp agglomeration of cement. 6, sprayed concrete experience with the ratio of cement 400kg / m3, the rate of 45-60% sand, water-cement ratio of about 0.4, using sand or coarse sand, coarse aggregate size 5-15mm better. Fourth, packaging alkali accelerator: 1, the product is bottled 200 kg / barrel, also determine other packaging according to user requirements. 2, this product is valid for one year. If more than valid, subject to inspection before using. 3, before use a little stirring.
