In fact, the development process of concrete mixer truck is the epitome of human progress and construction industry.
The earliest buildings of human beings were built with branches and stones. Later, there were buildings made of soil. The materials of these buildings are relatively simple.
Later, with the progress of society and the development of technology, in order to make the building more solid, began to use more complex building materials, such as concrete.
This requires the use of tools to mix and mix concrete made of a variety of materials. At the beginning of the 20th century, when concrete first appeared, the use of mixing concrete or manual mixing was a relatively primitive method, which was not only labor-intensive but also inefficient. The concrete was also used after mixing on site and would not be transported for a long distance.
In the 1970s, there was a fixed concrete mixer driven by electricity, and small carts were used to transport concrete in a short distance, so the efficiency was improved a lot.
In the 1980s, there were mobile mixers pulled by trucks.
Because concrete is made up of stone, sand, cement and water. If it doesn't rotate during transportation and keeps bumping, the stone will sink to the bottom, the sand will be in the middle, and the cement and water will be on the top. When the concrete is transported to the destination, it will agglomerate, which is also what we often call stuffy cans.
Therefore, the rotation can not only prevent the concrete from setting, but also prevent the concrete from layering, and can also make the concrete mix more evenly.
In the transportation process of concrete mixer truck, sometimes there will be various failures or long-term traffic jams, which will make the concrete solidify in the tank body, resulting in the phenomenon of filling the tank.
