CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material construction CGM high-strength non-shrinkage grouting material construction technical guidance, telephone - 15838304411. Part one, pits, grouting material appearance picture of pulp and many small pits, pitting, rough surface, but the unreinforced show picture. Attack the factor 1. Template looks rough or adhesive slag cement and other sundry not clean, when dismantle the grouting material appearance is damaged; 2. Template sprinkling water not wet or damp, grouting material moisture absorption to component appearance, make the grouting material excessive water loss presents pits; 3. Template flat-fell seam is lax, part of the slurry; 4. Template blocks the coating uneven seam an agent, or part of a brush or leakage failure, grouting material appearance and template binding pits; 5. Grouting material vibrating untrue, bubbles not discharge, parked in the template form pitting appearance scene. The prevention and treatment of method 1. Template looks clean, no glue hardened cement mortar etc sundry; Sprinkling water irrigation before grouting materials, the template should be energetic wet; Template gap, use the felt paper, putty, wall tightly; Template blocks the seam an agent should choose long-lasting, uniform coating, shall not leak brush. Grouting material should be layered homogeneous vibrating close-grained, to eliminate air bubbles to stop; 2. Appearance of painting, can not handle, appearance picture without paint, should be after full wet sprinkler piping parts, usable 1:2 or 2-1. Textured screeding with 5 cement mortar, the calender. Second, the appearance of uneven: rugged, grouting material appearance of indeterminacy of dispute or plate thickness and appearance. Attack the factor 1. After pouring of grouting material, appearance only beat with a spade, unused float leveling calender, constitute a rough appearance; 2. Template does not support on a hard soil layer, or the lack of supporting surface, loose or support, bubble water, causing a new irrigation attack uneven sinking when the early stage of the grouting material maintenance; 3. Grouting material has not arrived in strength must be, master cheng yen or material handling operation, make the appearance picture presents sub-sag, uneven or marks. Prevention and treatment of severe according to the construction of operating, casting after grouting material, should according to the level of symbol manipulation or play with potential float leveling, calender, after the final set sprinkler maintenance; Template should satisfy the strength, stiffness and stability should be supported on a solid foundation, with satisfy support area, and to avoid flooding, in order to make sure no attack sinking; When pouring grouting materials, strengthening inspection, strength of grouting material to reach 1. More than 2 n / ㎜ 2, has to be in on structure.
