Embodiment 1
[0018] The invention provides a stress-free penetrating water washing chiseling process, which is applicable to any concrete surface that needs chiseling, and the construction temperature of the whole process is within the range of +5°C to 40°C. This process includes the following steps:
[0019] (1) Construction preparation and installation of formwork for construction; the method and steps of installing formwork for construction are consistent with the existing construction technology. This process is used for the concrete surface that needs to be chiseled. Before using this process, prepare the concrete surface treatment retarder required by this process, the brushing equipment and water washing equipment required for this process on the basis of the original concrete construction preparation ( That is, the high-pressure water-filling equipment that needs to chisel the rough concrete surface for flushing), the brushing equipment and the water washing equipment are all prior...
Embodiment 2
[0056] On the basis of Example 1, when the step (3) brushes the concrete surface treatment retarder, leave a 1cm range around the formwork and do not apply it, so as to prevent the retarder from penetrating into the surrounding of the concrete, causing the range of chiseling to expand and edge falling , the contact surface is linearly damaged. If the retarder has penetrated into the surrounding concrete before it is air-dried, it will cause the edges to fall off and the range of chiseling will expand. In the step (4), the air-drying time of the retarder is 1-2 hours, and the concrete is poured after air-drying. The concrete surface treatment retarder mainly includes a retarder, a thickener and a film-forming agent. The concrete surface treatment retarder is a blended finished product provided by Guangzhou Zongyuan Building Materials Co., Ltd.: ZY-C concrete surface treatment retarder, which can be purchased directly from the company and does not need to be prepared by itself....
