What are the acceptance specifications for construction quality of concrete structure engineering?

Speaking of concrete, I believe everyone is familiar with it. Concrete is an indispensable material in the process of building construction. The quality of concrete directly affects the quality of houses. Therefore, it is necessary to know the acceptance standard of concrete structure engineering construction quality in advance. The following small series will tell you about the acceptance standard of concrete structure engineering construction quality and the matters needing attention in concrete pouring.

A, concrete structure engineering construction quality acceptance specification?

The quality acceptance of concrete structure should be carried out before the concrete surface is repaired and decorated, and after the formwork is removed. Records should be made in the process of acceptance. When checking the trimmed or reworked concrete structural members, check the contrast words and images before and after. Serious defects were found in the concrete structure during the acceptance, so it is necessary to supervise the construction unit to deal with them and re-accept them.

Second, what are the precautions for concrete pouring?

1, the concrete construction must be completed within 5 hours, so as to avoid cold joint of concrete during pouring, which will affect the construction quality. The construction time of concrete twice should be controlled within 1 half an hour, and the joint should be stirred with a vibrating rod until there is no bubble on the concrete surface and laitance is produced.

2. In the process of pouring beam-slab concrete, beam-column joints should be poured first, and at the same time, the beam-column joints should be vibrated and compacted. When the concrete building is about to be completed, it is necessary to estimate the remaining concrete beams and concrete quantity, and contact the mixing station to inform the other party of reasonable scheduling.

3. After the concrete building is completed, the concrete surface should be leveled with a scraper and roughened with a brush. After plastering the concrete surface for the second and third times, cover the concrete surface with plastic film immediately, and then sprinkle water after there is no water drop on the plastic film surface.

Summary: What are the relevant contents of the code for acceptance of concrete structure construction quality? The construction requirements of concrete structure are very strict, because it is directly related to the quality of the building, so the acceptance must be carried out in accordance with the relevant specifications and must not be sloppy.
