What CGM high-strength non-shrinkage grouting material is easy to appear quality problem - Henan zhengzhou high strength grouting material

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material solution, a surface phenomenon of hemp: local surface phenomenon appears short of grouting material and many small pits, pitting, form the rough surface, no assurance phenomenon but reinforcement grouting material a cubic no no no no 1 multiple reasons. Rough surface template or adhesive slag cement and other sundry not clean, open mould grouting material surface is destroyed; 2. Template was not enough water damp or wet, component surface grouting material moisture is sucked, grouting material excessive water loss occur pits; Template flat-fell seam 4. Template to isolate the coating uneven seam an agent, or local brush or leakage failure, grouting material surface and template binding pits; 5. Grouting material vibrating untrue, bubbles 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; Water the henan zhengzhou CGM high-strength non-shrinkage grouting manufacturer before grouting material, water templates should be fully wet; Template aperture, application felt paper, putty, etc, the template isolation beauty seam an agent should choose long-term, uniform coating, shall not be leakage brush. Grouting material should be layered homogeneous vibrating close & # 8203; ​ True, 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, mahjong surface flattening pressure light two, surface uneven phenomenon: grouting material surface uneven, or plate thickness is differ, the causes of uneven surface of 1. After pouring of grouting material, the surface beat with a spade, unused float leveling calender, surface rough; 2. Template is not supported on a hard soil layer, loose or insufficient bearing surface or support, bubble water, the new water infuse pulp uneven subsidence during early curing; 3. 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, casting after 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; Henan zhengzhou CGM high strength grouting material shrinkage in casting grouting materials, strengthening inspection, strength of grouting material reaches 1. More than 2 n / ㎜ 2, has to be in on structure. CGM Gao Qiangnai high temperature castable at http://www. godjc。 com/html/jqgj/24. 超文本标记语言
