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. 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. 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. 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.
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.
