全自动混凝土搅拌车的投料顺序!

混凝土搅拌车运营使用时,搅拌车生产出来的混凝土的质量与投料顺序密切相关。
When the concrete mixer is in operation, the quality of concrete produced by the mixer is closely related to the feeding sequence.
混凝土搅拌车原材料投料时,一般是先放石子,再放水泥,然后依次放沙子和水。为什么要这样投料呢?它是有讲究的,它的主要目的是保证石头、水泥等搅拌均匀,防止水泥与其他粗细骨料一起进入搅拌机,遇水后很快形成小水泥团,而影响混凝土质量,水灰比越小,这种团聚越严重。
When the raw materials of concrete mixer truck are fed, it is generally to put stones first, then cement, and then sand and water in turn. Why do you need to feed like this? It is fastidious. Its main purpose is to ensure that stones, cement, etc. are mixed evenly, and prevent cement from entering the mixer together with other coarse and fine aggregates. When it meets with water, it will soon form a small cement mass, which will affect the quality of concrete. The smaller the water cement ratio is, the more serious the agglomeration will be.

此外,因为小水泥团粒附着在粗骨料上,所以粗骨料的粒径越大,小水泥团粒破碎的可能性越小。
In addition, because the small cement aggregates adhere to the coarse aggregate, the larger the particle size of coarse aggregate, the smaller the possibility of small cement aggregates breaking.
在搅拌过程中,由于摩擦和冲击,骨料运动方向后方的小水泥颗粒受到有效保护,粒径比小水泥颗粒大几倍或十几倍的粗骨料成为小水泥颗粒的保护屏障。
In the process of mixing, due to friction and impact, the small cement particles behind the moving direction of aggregate are effectively protected, and the coarse aggregate whose particle size is several times or more than ten times larger than the small cement particles becomes the protective barrier of the small cement particles.
有些水泥颗粒搅拌后不能破碎,硬化后成为水泥块填充骨料空隙,导致商品混凝土强度下降,甚至出现质量事故隐患。
Some cement particles can not be broken after mixing, and become cement blocks after hardening to fill the aggregate voids, which leads to the decrease of commercial concrete strength, and even the hidden danger of quality accidents.
