In the past few years, in order to strengthen the construction and management of cities, improve the quality of construction projects across the country, reduce noise at construction sites and protect the environment, the State has issued work prohibiting mixing mortar in construction sites in urban areas of large and medium-sized cities throughout the country. This paper report brought a big spring to the development of cement mixers . What role does the cement mixer play in construction?
In the construction work of the construction site, the role of the cement mixer is to transport the cement from the pumping station to each construction site. The cement pump truck then pumps the cement to a designated place or dumps it directly on the road to be constructed. In the process of transportation, the pipe body on the concrete transporter always keeps rotating, and the rotation is always to prevent the concrete from being segregated. (The explanation here is about what is segregation, that is, the lack of cohesion of each material in the concrete, resulting in heavy The sinking of the material and the separation of the components of the concrete mix). Always turning keeps the concrete from freezing. Â
According to the water content of the concrete contained in the concrete mixer truck, the concrete mixer truck can be divided into three types. There are three kinds of wet-type mixers, dry-type mixers and semi-dry-type wet mixers. However, according to Xiao Bian's visual inspection on the street, most of the domestic use of wet concrete mixer trucks. Concrete mixers add sand, gravel, cement, and water to the pumping station to mix themselves during transportation and transport it to the construction site. Of course, these ingredients need to be added to the concrete mixer truck according to the proportion. However, the general transportation process should not exceed 1.5 hours, otherwise the concrete will solidify even if it is kept stirring. Therefore, long-distance transportation concrete generally uses dry material transportation or semi-dry material transportation.
After the mixer truck is used, it must be flushed with water in time. Otherwise, the concrete will freeze on the tubular body of the concrete transport vehicle. This will result in a significant reduction in the shipment volume of the cement truck. The above is a brief introduction of Xiao Bian's cement mixer .
