M50 liquidity non-shrinkage mortar construction methods - right Price of M50 liquidity non-shrinkage mortar

M50 liquidity non-shrinkage mortar M50 liquidity non-shrinkage mortar construction method in the construction site, M50 liquidity non-shrinkage mortar correct construction method can avoid the M50 liquidity non-shrinkage mortar quality problem, so the M50 liquidity non-shrinkage mortar in construction, easy to appear the quality problem? We should be how to correctly use the M50 liquidity non-shrinkage mortar, and avoid the damage of quality? M50 liquidity non-shrinkage mortar right construction steps: 1, preparing mixing machine, grouting equipment, template and maintenance items, cleaning up grouting space and the concrete surface wetting ahead of time. 2, a template with concrete ( Sand) Pulp, plastic tape block template connection put to ensure that no leakage, leakage. 3, according to the 12 - M50 liquidity non-shrinkage mortar weight Stir in water quantity and water (15% Mechanical stirring 2 - 3 minutes, artificial mixing 5 minutes or more) 4, will mix the M50 liquidity non-shrinkage mortar from one direction injection grout. When must use bamboo stick or steel rod guide, can be appropriately vibrating or tap the template. 5, after the completion of construction shall be immediately covering plastic film and the careless or quilt wet curing 3 - 7 days. 6, the use of temperature for - 10 ℃ and 40 ℃. It is strictly prohibited in the M50 liquidity non-shrinkage mortar mixed with any outside beauty seam an agent or additive is applied. M50 non-shrinkage mortar fluidity liquid level M50 liquidity without shrinkage of mortar is easy to appear the following quality problem; Qingpu M50 non-shrinkage mortar a liquidity, piping phenomenon: M50 non-shrinkage mortar local surface phenomenon appears short of liquidity 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 M50 liquidity non-shrinkage mortar surface are destroyed; 2. Template was not enough water damp or wet, component surface M50 liquidity non-shrinkage mortar water drawn into, make the M50 excessive liquidity non-shrinkage mortar water loss appeared pits; Template flat-fell seam 4. Template to isolate the coating uneven seam an agent, or local brush or leakage failure, M50 liquidity without shrinkage and template binding mortar surface pits; 5. M50 non-shrinkage mortar vibrating false sex flows, 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 M50 liquidity non-shrinkage mortar, the template should be watering full moisture; Template aperture, tarpaulin, putty, etc, uniform coating, brush M50 liquidity non-shrinkage mortar shall not be leakage should be layered homogeneous vibrating close-grained, until the exhaust 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. Textured screeding with 5 cement mortar, the calender. Second, the surface uneven phenomenon: M50 liquidity non-shrinkage mortar surface uneven, or different plate thickness, surface rough. The causes of 1. M50 liquidity contraction without mortar pouring, beat surface 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 M50 liquidity non-shrinkage mortar uneven subsidence during early curing; 3. M50 liquidity non-shrinkage mortar have 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 M50 liquidity contraction without mortar should be according to the level of control or marker play potential with zhengzhou pisolite reinforcement M50 liquidity contraction without mortar leveling, pressure light, after the final set water conservation; Template should have enough strength, stiffness and stability should support on the solid foundation, has enough support area, and to prevent flooding, to ensure not occur sink; When casting M50 non-shrinkage mortar liquidity, strengthen inspection, M50 liquidity without mortar strength reaches 1. More than 2 n / ㎜ 2, has to be in on structure. Above the building materials of M50 liquidity non-shrinkage mortar construction method and construction problems easy to make detailed answers, you should read this document in the construction, can avoid the problems encountered in construction, and cannot be solved.
