The characteristic of concrete is that it is easy to dry, especially when it is put for a long time, the water evaporates. When transporting concrete, it needs to use concrete mixer to transport and mix at the same time. Prevent concrete from drying. Why does the mixer still turn on the road?

　　1、为了获得混凝土配比和质量和减少工地施工场地占用，房屋提高建筑进度，缩短建筑工期，对于高层楼房的建筑，混凝土从原来工地现配进化成了更为的混凝土公司生产配送制；

　　1. In order to obtain the concrete proportion and quality, reduce the occupation of the construction site, improve the building progress and shorten the construction period, for the high-rise buildings, the concrete has evolved from the original site to a more advanced professional production and distribution system of the concrete company;

　　2、江南app平台官网 车在混凝土公司装车后，因从装完车到工地还有一段比较长的运输距离，为了防止混凝土在运输过程中结块，在配制混凝土的配方中加入了一定量的缓凝剂；

　　2. After the concrete mixer truck is loaded in the concrete company, because there is a relatively long transportation distance from the loading to the construction site, in order to prevent the concrete from caking in the transportation process, a certain amount of retarder is added to the formula of concrete preparation;

　　3、如果江南app平台官网 车不搅拌，在运输过程中，混凝土中的石头就会沉入底层，中间层是砂子，上层是水泥浆，并且运输到工地后就会出现结块的现象，因此，在运输过程中转动既可防止混凝土结块，又可防止混凝土分层，让混凝土混合得更均匀。

　　3. If the concrete mixer does not mix, during the transportation process, the stone in the concrete will sink into the bottom layer, the middle layer is sand, the upper layer is cement slurry, and the phenomenon of caking will appear after the transportation to the construction site. Therefore, the rotation in the transportation process can not only prevent the concrete from caking, but also prevent the concrete from layering, so that the concrete can be mixed more evenly.

　　大家不难发现，经过江南app平台官网 车运输的混凝土，它们的性能基本上保持不变，也没怎么干结，并且几乎不会被浪费，这基本上是该搅拌车的功能，在路上还转动是为了让混凝土保持其性能。

　　It is not difficult to find that the performance of the concrete transported by the concrete mixer truck is basically the same, not very dry, and almost not wasted, which is basically the function of the mixer truck, and the purpose of turning on the road is to keep the performance of the concrete.
