CGM high-strength non-shrinkage grouting material with the six methods of winter construction should be paid attention to - Nanjing grouting material manufacturers

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material price CGM high-strength non-shrinkage grouting material factory 1, add water: in order to the factory inspection report ( The water cement ratio, 0. 125 - 0. 135). The water content ( Room temperature 25 ℃) Water added as a parameter, the practice should be confirmed by field test match. Add water not too much, lest cause slurry bleeding and segregation. Water use room temperature of clean water, to ban the use of frozen water, high strength without shortening the CGM high-strength non-shrinkage grouting material should also avoid cold. 2 basf CGM high-strength non-shrinkage grouting material price, the mixing solution: use the mortar mixer mixing ( Mixing blade speed - 40 80 r/min) , first feeding, add water while mixing, mixing after 3 minutes, until the uniformly grouting. A quantity of mixing with a dosage of bearing hole of the advisable. Loss of liquidity material cannot be used again to add water. 3, the grouting method: after grouting, not continuous and shorten the grouting time as much as possible. In taian high strength at room temperature under the CGM high-strength non-shrinkage grouting material, should be at the beginning of the water mixing meter end grouting within 10 minutes. Ban on vibrating grouting process, if necessary, can use of bamboo, such as steel pull diversion. After grouting dense, slightly dry, rub the surface flat light. 4, pay attention to matters: shall ensure that high strength without shortening the CGM high-strength non-shrinkage grouting material slurry consistency. Grouting body length width is bigger than bearing plate 80 mm ( 40 mm per side) , the thickness of 20 ~ 30 mm. Grouting body should be higher than the bearing plate 3 mm, grouting from bearing on one side to the other side of the infusion, or from the middle to perfusion, prohibit perfusion in the four corners, to avoid air leakage, the scene make specimen, maintenance test after 2 hours. Strength of specimen 20 mpa can unload jacks, settled through hole. 5, construction filler: CGM high-strength non-shrinkage grouting material construction before, to clear the clutter that grouting hole, to be filled with high pressure pumps bearing hole of the eluvial soil, loose things blow clean, grouting is it necessary to clean the surface of the frozen water. Padding: eluvial soil, loose materials and prewetting water will help increase the high strength without shortening the CGM high-strength non-shrinkage grouting material and the degree of binding between roots, or you will fall between grouting body and foundation, the combination of severe is may make grouting body away from the roots. 6, maintenance way: grouting body after the final set, pay attention to heat preservation maintenance. Use straw mat, such as quilt cover maintenance, maintenance period for 3 ~ 7 days. Padding: high strength without shortening the CGM high-strength non-shrinkage grouting material with high intensity, hydration heat and focused, inadequate maintenance is not timely, will produce crack. The site making specimen 6 set ( Specimen width of 40 * 40 * 160) Respectively for 2 hours, 56 days, 28 days, 24 hours a day, 90 days, in the manufacturing after 1 hour, specimens shall be soaking in the water together with the die maintenance to ensure that the compressive strength of 2 hours.
