Concrete pouring
Release time:
2020-07-07
concrete pouring should comply with the corresponding construction specifications, special attention should be paid to:
1, concrete in the construction of water-absorbing objects involved in the corresponding treatment before pouring, in order to avoid concrete moisture absorption, affecting the quality of concrete.
2, concrete should be poured before the initial setting, and there can be no segregation phenomenon, if there is segregation phenomenon, should be re-mixing, before pouring, and pouring process should also avoid segregation phenomenon.
3. When pouring structures such as columns, a layer of 50-100mm cement mortar (the mix ratio is the same as that in concrete) shall be poured at the bottom to avoid honeycomb pitting.
4, concrete pouring, should be carried out in layers according to the structural requirements, with pouring and tamping.
5. The overall concrete pouring of general structures shall be carried out continuously as much as possible to avoid intermittent construction. In the initial stage after concrete pouring, the concrete shall be protected from vibration or impact.
7. When making cement floor, roof platform and other parts, attention should be paid to the plastering operation. Generally, it should be plastered many times until there is no bleeding on the surface, but dry powder should not be sprinkled and cured in time during the plastering process.
8. In order to prevent early cracks in road construction, attention should be paid to:
①. Under the condition of meeting the design grade of concrete, accurate measurement should be made, excessive cement should not be used, and the unit water consumption of concrete should be mastered to reduce the shrinkage of concrete.
②, do not use high-temperature cement, the cement temperature during site construction should be lower than 70 ℃. In summer construction, the pouring temperature of concrete should be reduced as much as possible, the operation time from the beginning of pouring to the completion of surface finishing should be shortened, and the concrete should be fully cured. Regardless of the circumstances and conditions, the temperature of the concrete mixture shall not exceed 35 ℃. During winter construction, the mixing time should be extended, and the discharge temperature should not be lower than 10 ℃. At the same time, after the construction of pavement concrete, the first three days of maintenance temperature should be maintained above 10 ℃, the next 7 days of maintenance temperature should be maintained above 5 ℃.
③. When using dry aggregate exposed to sunlight for a long time, water shall be fully sprinkled to cool down.
④, the top surface of the base should be fully wet before pouring concrete, or take waterproof measures.
⑤, concrete surface finishing process, to avoid direct sunlight, do not make the temperature rise and dry.
⑥. According to the strength development, master the appropriate time for plate cutting to prevent the concrete slab from breaking.

More information
In the eastern corner of the production area of Jianfeng Health Technology Company, there is a very inconspicuous building. From below, only a few pipes of uneven thickness can be seen on the top and the slogan "Focus on Environmental Protection and Promote Sustainable Development" with red letters on the yellow background on the stainless steel guardrail. Walking up, you can only see several closed pools and a small room with stacks of documents, test tubes, glass bottles and other testing tools on the table. This is the peak and healthy sewage treatment station. The production sewage of the whole factory area is concentrated here. After adjustment (PH adjustment), pre-acidification, anaerobic, anoxic, aerobic (aeration), precipitation and other links, it is discharged into the pipe network after reaching the special discharge standard. Yin Zhiwu, executive deputy general manager of Jianfeng Health, said that because the sewage treatment station in Wucheng District has not yet been built, Jianfeng Health has not yet been able to achieve pipe discharge, and the relevant national laws have strict requirements on the discharge of water pollutants from the extraction pharmaceutical industry. Sewage discharge must reach a special discharge limit, that is, chemical oxygen demand (COD) must be less than 50 mg/L. Enterprise development and environmental protection are both the concept of peak health since its establishment. In March this year, on the basis of the original environmental protection facilities, Jianfeng Health carried out technical renovation of waste gas collection and treatment facilities, and at the same time installed a sealing cover on the sewage treatment station to realize the closed collection of waste gas. Since the trial operation of this facility in mid-May, the overall effect has been obvious. The original treatment tank would emit an unpleasant smell during work, but now the smell has been significantly reduced. Compared with the young enterprise of peak health, the relatively "older" peak pharmaceutical has more experience in sewage treatment and environmental protection. Akihama
