在浇注现浇板时,塑料薄膜必须与盖摩擦。为了防止现浇板裂缝,最好的办法是铺上覆膜的塑料薄膜,但只允许在线路放置时切断线路的一部分。润湿砂浆砂浆的均匀织物:当泵送混凝土时,原浆砂浆必须均匀分散,不集中;砂浆强度低,砂浆集中在一处,局部强度低。浇筑板坯时,浇筑墙柱时砂浆的分布面积不小于100,不小于50。根据公司的《泵操作员操作规程》。

混凝土墙拆除后,立即洒水或刷洗固化液:在春、夏、秋季,可安排混凝土墙体喷洒不少于7天的特殊人员。每日喷水数不少于15次,在春季,风干期不应少于24次,夜间不能中断。冬季应使用电刷固化液。根据“预混混凝土技术底”浇筑施工的要求,供应商应向买方提供“预拌混凝土技术底”,并要求需方技术和施工人员认真研究地基。改变只归档信息的条件,但不使用它。现场调度、销售人员应按要求对施工进行监督。

拆柱后,必须立即将塑料薄膜包裹起来:将塑料薄膜包裹在立柱表面是保持立柱混凝土的最佳方法。它可以保护混凝土水分从外部蒸发,以满足硬化需求的混凝土。当需要粉刷时,可以除去胶片。混凝土墙保持不变。刷固化液也可用于春、夏、秋季,但应保证固化液是合格的产品,即在清洗后的壁上形成固化膜。对于混凝土养护,请参阅我公司的《混凝土养护专项技术报告》。




When pouring the cast-in-place board, the plastic film must be rubbed with the cover. In order to prevent the cracks in the cast-in-place board, the best measure is to follow the plastic film covered with the cover, but it is only allowed to cut out the way part of the line when the line is placed. The uniform fabric of the embellish mortar mortar: when the concrete is transported with a pump, the original pipe mortar must be dispersed evenly and not concentrated; because the strength of the mortar is low, the concentration of the mortar at one place will make the local strength low. When pouring the slab, the distribution area of the mortar is not less than 100, when pouring the wall column, not less than 50. According to the company's "pump operator's operation instruction".


Immediately sprinkle water or brush curing liquid after the concrete wall is dismantled: in spring, summer and autumn, a special person can be arranged for the concrete wall to be sprinkled for no less than 7 days. The daily sprinkler number is not less than 15 times, in the spring, the wind drying period should not be less than 24 times, and the night can not be interrupted. The brush curing solution should be used in winter. According to the requirements of "pre mixed concrete technical bottom" for pouring construction, the supplier should provide "pre mixed concrete technical bottom" to the buyer, and require the demand side technology and the constructors to study the foundation carefully. Change the condition of filing only information but not using it. The on-site dispatching and sales personnel should supervise the construction according to the requirements.


After the column is dismantled, the plastic film must be wrapped up immediately: wrapping the plastic film on the surface of the column is the best way to maintain the column concrete. It can protect the moisture in the concrete from outside evaporation to meet the hardened demand of concrete. The film can be removed when the plastering is needed. The concrete wall is maintained. Brush curing solution can also be used in spring, summer and autumn, but it should be ensured that the curing solution is a qualified product, that is, the film can be formed after washing the curing solution on the wall. For concrete maintenance, please refer to our company's "concrete maintenance special technical disclosure".
