Wind and grouting prestressed precast concrete wind turbine tower drum specification

Wind wind power wind grouting material price grouting grouting material manufacturer special wind CGM high-strength non-shrinkage grouting material service I 5 3 8 August 3 O 4 4 I (I Can directly add WeChat) CGM wind special grouting material, is a kind of by optimizing cement as the main gelled material, with high strength aggregate as reinforced material, supplemented by poly carboxylic acid high performance water reducing the seam an agent, expansion the seam an agent and polymer latex powder and other high and new materials, based on the active powder and compounded tight stacking principle, wind power and other large equipment foundation grouting treatment used for the cement base composite materials. A, CGM high-strength non-shrinkage grouting material for wind power characteristics 1, early strength, high strength, high durability, good resistance to chloride ion permeability and antifreeze performance; 2, high flow, water pumping, not secrete, construction is convenient; 3, compound double expansion effect, no contract; 4, for reinforcement corrosion. Second, CGM high-strength non-shrinkage grouting material for wind power performance index CGM wind special grouting material fluidity of product model C80C90C100C110 main performance index, mm initial value 340 or 290 or 340 or 29030 min or higher retention value 310 260 or 310 or 260 or higher or more vertical expansion rate of % 3 h0. 1 to 3. The difference between the 524 h and 3 h expansion value 0. 02 ~ 0. 5 compressive strength, MPa1d 30 or 40 or higher acuity 30 503 d 40 or 60 or more acuity or 50 or 4028 d, 80 or 90 or 100 or 110 or higher bending strength, MPa28d 10 p 16 effect on reinforcement rustily or without antifreeze level acuity F150 materials dosage, kg/m&sup 3; 2200 note: 1, the above data in a standard laboratory measurement control conditions; 2, please refer to the GB/T50448 - product application 2015 'cement grouting material application technical specifications'. Three, CGM high-strength non-shrinkage grouting material for wind power application range 1, wind power and other large equipment foundation secondary grouting; 2, anchor bolt anchor grouting; 3, the corrosion of equipment foundation; 4, seismic structures, and heavy machinery. Four, CGM high-strength non-shrinkage grouting material for wind power usage: 1, the basic surface concrete surface cut hair, bolt hole in the dust or grit blasting, clean metal surface grease or rust treatment. Use clean water to soak in advance based on the surface of concrete, grouting concrete foundation shall be no MingShui. 2, appropriate USES mechanical mixing. Mixing time to join the first two-thirds of the total water consumption mix for 3 minutes, then add the remaining one-third of water mixing until until smooth and uniform consistency condition. 3, water than: water ratio of 12. 5%. 4, wind power base grouting material, starting from the side grouting, until the other side of the overflow, shall not be from relative colleagues grouting on both sides. At the start of the grouting, should be carried out continuously, and shorten the grouting time as much as possible. 5 shall timely after grouting, water conservation, and sealed by the wet straw bag or plastic film, maintenance time is not less than three days. Five, the wind power dedicated CGM high-strength non-shrinkage grouting material matters needing attention, the product should be in 5 to 1 Temperature 30 ℃ environment use, beyond the above products could shorten the coagulation time or delay, winter construction matters needing attention please inquire manufacturers. 2, this material may not be with any other cement mixing, also may not add any additional seam an agent. 3, this material used as soon as possible after mixing pulping, after the loss of liquidity, shall not be used to add water mixing. Six, wind power is special packaging and storage of CGM high-strength non-shrinkage grouting material 1, CGM wind power special grouting material with pearly membrane composite woven bag packing, 50 kg/bag. 2, should be stored in a cool, dry and ventilated warehouse, not the rain. 3, from the date of production, effective storage period is 6 months.
