影响混凝土施工技术的因素有许多,对于当前的混凝土施工情况来讲,只有对建筑工程施工过程进行控制,将混凝土施工技术进行严格规范化,才能使混凝土施工技术不断提高。建议大家在混凝土搅拌机配料和搅拌过程依据下面这些标准。
There are many factors that affect the concrete construction technology. For the current concrete construction situation, only by controlling the construction process and Strictly Standardizing the concrete construction technology, can the concrete construction technology be continuously improved. It is suggested that the following standards should be followed in the batching and mixing process of concrete mixer.
(1)配料准备前提
(1) Preparation of ingredients
水泥进场的时候,要按照级别、包装、品种、出厂日期、装配仓号等进行一一检查,而且还要对安全性、强度等性能指标实行复验制度。其质量一定要符合国家标准。如果在使用过程中,对水泥的质量与出厂日期产生质疑,可以要求复验,复验不合格的水泥产品,不得继续使用。预应力混凝土中,绝对不能使用含有氯化物水泥。
When entering the site, the cement should be inspected one by one according to the grade, package, variety, date of delivery, assembly warehouse number, etc., and the safety, strength and other performance indicators should be re inspected. Its quality must conform to the national standard. If the quality and delivery date of cement are questioned in the process of use, re inspection can be required. The unqualified cement products shall not be used any more. Chloride containing cement must not be used in prestressed concrete.
(2)混凝土配合比要求
(2) Concrete mix proportion requirements
在正式配料之前,应当要进行配比实验,而不得根据经验进行配比。在保证水泥质量的同时,也要注意合理与经济的原则。对于检查发现的错配、少配、漏配的混凝土禁止出仓。生产混凝土过程中,石、砂实际含水量可能同设计配比含水量有差距,施工中要随时根据现场测试结果进行配合比调整。
Before the formal batching, the proportioning experiment should be carried out instead of the proportioning based on experience. While ensuring the quality of cement, we should also pay attention to the principle of rationality and economy. It is forbidden to leave the warehouse for the concrete that is found to be mismatched, insufficient or missing. In the process of concrete production, there may be a gap between the actual water content of stone and sand and the water content of design mix proportion, so the mix proportion should be adjusted at any time according to the field test results.
(3)对投料量的要求
(3) Requirements for feeding quantity
搅拌机承载混凝土量不应过多,投料量应控制于搅拌机额定容量以下。根据施工配合比、搅拌机型号,对投料量进行科学要求。更多技术问题请关注本站http://www.zkhntjbc.com更新。
The concrete bearing capacity of the mixer should not be too much, and the feeding amount should be controlled below the rated capacity of the mixer. According to the construction mix proportion and mixer model, scientific requirements for the feeding amount are made.
