CGM high-strength non-shrinkage grouting material prone to quality problems and measures

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material price CGM high-strength non-shrinkage grouting material manufacturer, ballast-surface phenomena: CGM high-strength non-shrinkage grouting material local surface phenomenon appears short of pulp and many small pits, pitting, rough surface formation, but no reinforced the leakage phenomenon. The causes of 1. Rough surface template or adhesive slag cement and other sundry not clean, dismantle CGM high-strength non-shrinkage grouting material surface is destroyed; 2. Template was not enough water moist or wet, zhengzhou CGM high-strength non-shrinkage grouting reinforcement component table surface CGM high-strength non-shrinkage grouting material moisture was drawn to, make the CGM high-strength non-shrinkage grouting material appears excessive water loss pits; 3. Template flat-fell seam is lax, local slurry leakage; 4. Template to isolate the coating uneven seam an agent, or local brush or leakage failure, CGM high-strength non-shrinkage grouting material surface and template binding pits; 5. CGM high-strength non-shrinkage grouting material vibrating untrue, bubble not discharge, parked in the template form pitting surface phenomenon. Prevention and cure measure 1. Template surface is clean, can not with hardened cement mortar etc sundry; Before watering CGM high-strength non-shrinkage grouting material, template should be watering full moisture; Template aperture, application felt paper, putty, wall tightly; Template to isolate the seam an agent should choose long-lasting, uniform coating, shall not be leakage brush. CGM high-strength non-shrinkage grouting material should be layered homogeneous vibrating close-grained, to eliminate air bubbles; 2. Surface for painting, don't processing, surface paint, should be in the water piping parts fully wet, usable 1:2 or 2-1. 5 cement mortar, there can be no shrinkage concrete CGM high-strength non-shrinkage grouting material granulating screeding calender. Jiangxi CGM high-strength non-shrinkage grouting material manufacturer surface uneven phenomenon: CGM high-strength non-shrinkage grouting material surface uneven, or have different plate thickness, surface rough. The causes of 1. After pouring of CGM high-strength non-shrinkage grouting material, the surface only beat with a spade, unused float leveling calender, surface rough; 2. Template is not supported on a hard soil layer, or insufficient bearing surface, or loose and bubble water, pour out the new CGM high-strength non-shrinkage grouting material uneven subsidence during early curing; 3. CGM high-strength non-shrinkage grouting material has not reached a certain strength, master cheng yen or material handling operation, concave surface appear uneven or marks. Prevention measures in accordance with the construction of the operation, after casting CGM high-strength non-shrinkage grouting material, should according to the level of control marks or play with potential float leveling, pressure light, after the final set water conservation; Template should have enough strength, stiffness and stability should be supported on a solid foundation, has enough support area, and to prevent flooding, to ensure not occur sink; When casting CGM high-strength non-shrinkage grouting material, strengthening inspection, CGM high-strength non-shrinkage grouting material strength reaches 1. More than 2 n / ㎜ 2, has to be in on structure.
