Classification Of Cement Mixer Trucks

According to the water content of the concrete transported by the concrete mixer truck, there are three types of mixer trucks: wet, dry and semi-dry. Most domestically, wet concrete mixer trucks are used. They can transport concrete produced by a mixing plant (station) or aggregates (sand, gravel), cement and water mixed according to a certain ratio. During transportation, the wet materials are continuously and slowly stirred to prevent the initial setting and segregation of the concrete during transportation. However, the time from production to pouring of concrete generally cannot exceed 1.5 hours to prevent the concrete from setting. Therefore, in the case of longer-distance transportation, dry and semi-dry mixer trucks are required for transportation. The dry mixer truck can directly load dry aggregates and cement into the mixing drum of the truck according to the ratio. The dry materials in the drum are stirred during transportation. When the vehicle is about to arrive at the construction site or at the construction site, water is added to complete the mixing of the concrete. The aggregates and cement in the concrete transported by the semi-dry mixer truck are also prepared according to the proportion and contain a certain amount of water, but the water content does not meet the pouring requirements. Water needs to be added and mixed when the vehicle is about to reach the construction site or at the construction site.
