Why does the tanker keep turning?
May see clearly, think it is tanker, in fact, concrete tank car.
Mixing station, the machine just out of the concrete is the initial material, only in the ingredients after simple mixing, in order to ensure the uniformity of the concrete, need to stir in the mixer for two times.
Tanker transportation two stirring belongs to deep processing, but it is not a simple rotation of the body rotation times of homogeneity of concrete is particularly important, 6~8 should be /min; coarse aggregate concrete is too slow, too fast, easy to sink, for the safety of the driver has a certain influence, but also will increase the concrete water passes, the slump increases, effect of unloading; 6~8 /min, the initial setting time of concrete in 3~6 hours. A traffic jam very little effect on concrete, if the traffic jam time is too long, the concrete tank rotation times to speed up the 1~2 circle and appropriate, should always pay attention to the rotation is abnormal, the appropriate time can add water to maintain the workability of concrete and avoid sticky pot and pot.
