The mixing quality of Zhongke concrete mixer is not only related to raw materials and equipment, but also closely related to mixing time. The mixing time of the concrete mixer refers to the time from the completion of loading to the start of unloading, which can be determined according to the slump of the mixer and the capacity of the concrete mixer. Make sure to mix evenly.
Generally, the mixing time of small and medium-sized concrete mixers is 1-2 minutes, and the mixing time is about 3 minutes by using the method of "water slurry and stone wrapping". The mixing time of the forced concrete mixer is short, such as jd200 concrete mixer, which can only be used for 30 seconds. In a word, it can be determined by test according to the actual situation of construction. Small slump (mechanical tamping 1-2cm, manual tamping 2-4cm), admixture, fine sand concrete, the mixing time can be extended according to the actual situation.
