1. In order to obtain better concrete, quality and reduce the construction site, improve the construction progress and shorten the construction period.
2. When the concrete mixer is loaded by the concrete company, there is a long transportation distance from the completion of loading to the construction site. In order to prevent concrete from caking in the process of transportation, a certain amount of retarder is added to the formula of concrete preparation.
3. If you don't mix the concrete mixer, during the transportation, the stone will sink in the bottom of the concrete, the middle layer is sand, and the upper layer is cement slurry. After the concrete is transported to the site, there will be caking. Therefore, the rotation of the concrete mixer can prevent the concrete from sticking during the transportation, and can prevent the concrete layer, so that the concrete can be mixed more evenly.
4. Now the concrete is transported by special concrete companies and then by concrete mixers on the construction site. During this period, if you don't mix with mixers, the stones, sand and cement mortar in the concrete will be layered, and there will be caking after the website, so the concrete mixers of the traffic engineering will keep running, which can prevent the concrete from bonding, and prevent the concrete from layering, It can also make the concrete mix more evenly, which is "three all its beauty".
To sum up, the main purpose of the concrete mixer moving on the road surface is to prevent the concrete from caking in the transportation process, so as to make the sand, stone and cement in the concrete more uniform.
