It is believed that everyone knows that under the same construction environment, using the same construction technology, different conditions of the basement concrete (including fine stone concrete) will bring about the construction quality (including color, strength and wear resistance) of the cement wear-resistant floor. The corresponding impact. Here we introduce: wear-resistant floor construction requirements and precautions.
Wear-resistant floor construction requirements (concrete pouring party requirements):
1 The concrete strength is not lower than C25, the water-cement ratio is not higher than 0.5, and the maximum diameter of the concrete gravel is not more than 30MM (the diameter of the fine stone concrete is no more than 10MM).
2 The formation is required to be compacted, and then the template is to be set. The template should be smooth and firm. The design template of the elevation is to be designed according to the floor. The width of the template should be 6 meters, and the elevation and level of the template should be controlled by the spirit level.
3 The slump of concrete is controlled within 12CM plus or minus 2CM.
(1) Set the template according to the design elevation, and use the spirit level to press the template elevation and level. For the dry mortar floor, the base must be thoroughly mixed with water to ensure sufficient moisture.
(2) Blanking: All personnel are not allowed to step on or touch the channel steel.
(3) Leveling: The concrete screed guarantees smoothing with pouring.
(4) Vibrating: Fully vibrate and compact with a plug-in or plate vibrator.
(5) Scrape the first pass: Scrape the surface of the channel with a 6-meter scraper.
(6) Roller rolling: Clean the surface of the channel steel, roll it with the roller, and repair the uneven surface until the surface is flooded with grout (usually three times for repeated rolling).
(7) Scrape the second time: After the drum is fully pumped, use a 6-meter scraper to scrape the surface of the channel for a second time to ensure flatness.
(8) Demolition: Remove on the third day after the construction of the wear-resistant floor is completed.
(9) Trimming: After the mould is removed, the edge of the floor edge is cut off by the stencil and cut to ensure the flatness and aesthetics of the jointed concrete pouring edge.
(10) The above construction requirements must be supervised by Party A in the successful implementation of the civil construction side (concrete pouring side).
Wear-resistant floor construction notes:
1 As the construction of wear-resistant materials and the pouring of concrete floors are carried out almost at the same time, in order to ensure the construction quality and construction progress of the wear-resistant layer, the mixing and pouring shall be well coordinated.
2 The template setting should be smooth and firm. The template should be 6 meters and coated with stripping oil. The level of the template should be checked at any time with the spirit level. The deviation should be adjusted in time.
3 The concrete strength is not lower than C25, and the water-cement ratio is as small as possible.
4 Use an insert vibrator and a flat plate vibrator. After vibrating, measure the level of the template using a spirit level and adjust the deviation.
5 Use heavier steel long rollers (steel rollers should be wider than the template) repeatedly pressure and keep the steel mold clean, so that the floor is flat, can not use the steel roller working parts, apply scraping ruler leveling.
6 on the serious parts of bleeding, apply rubber tube to bleeding water.
7 mold release is best done on the second day after the wear-resistant surface layer, the third day by the building cut expansion joints.
8 During the construction period of Party B, no cross construction shall be arranged and shall be responsible for protection and maintenance of the completed floor of the other party. Party A shall provide water and electricity.
Editor's summary: Wearable floor construction requirements and precautions are introduced here, I hope to help you, more information please pay attention to this site.
