载满混凝土的搅拌车走在路上，托着很大的滚桶，传出轰隆轰隆的响声，在行车的全过程中，后边的滚桶也在不断的旋转，看起来还一些恐怖。那么为何搅拌桶要一直不断地转动呢？

The mixer truck loaded with concrete is walking on the road, holding a large drum, and there is a roaring sound. During the whole process of driving, the drum at the back is constantly rotating, and it looks horrible. So why does the mixing drum keep rotating?

为何搅拌桶要一直不断地转动呢？那样做主要是以便不许里边承重的混凝土发生离析和终凝。那麽发生离析和初凝会导致哪些不良影响呢?当发生离析的情况下，混凝土里边的水泥砂浆凝聚力量会大幅度降低，没法爬取块状的砂砾石。

Why does the mixing drum keep rotating? This is mainly to prevent segregation and final setting of the bearing concrete inside. What are the adverse effects of segregation and initial setting? In case of segregation, the cohesive force of cement mortar inside the concrete will be greatly reduced, and it is impossible to climb the massive sand gravel.

而发生离析的混凝土，它的抗压强度会降低，这样一来对工程施工会导致不好危害。对于初凝，说白了，就是混凝土刚开始由软发硬，而不可以再随便地更改样子。假如搅拌桶一直不运行，伴随着时间的流逝，混凝土愈来愈硬，很后会变成一块硬实的大砖块，还如何使用呢?

The compressive strength of concrete with segregation will be reduced, which will cause bad harm to the construction. For the initial setting, to put it plainly, the concrete starts from soft to hard at the beginning, and the appearance can not be changed arbitrarily. If the mixing bucket has not been running, with the passage of time, the concrete will become harder and harder, and will soon become a hard brick. How can we use it?

那么，是否搅拌桶运行的越是快就越好呢?回答是否认的。假如拌和得过快，在其中的水份会过多的挥发掉，进而造成品质上的一些难题。一般而言，拌和很适合的速度是每分10-30转，那样是较为有效率。如果是夏季的话，因为室外温度自身就高，以便降低挥发，速率要再慢一点儿。

So, does the faster the mixing drum runs, the better? The answer is No. If mixing is too fast, the water in it will volatilize too much, which will cause some problems in quality. Generally speaking, the suitable mixing speed is 10-30 revolutions per minute, which is more effective and efficient. If it is summer, because the outdoor temperature is high, so as to reduce volatilization, the rate should be slower.

当运送到到达站后，要立即地自来水冲洗掉早已发生硬底化的混凝土，便于维持桶内容量的利润很大化。现阶段而言，在我国的搅拌车容积从3-18立方米都是有。一辆12方的闲置的搅拌车大概重为16吨。假如所有放满的话，一立方米混凝土的净重依照2.4吨计算出来，整辆车就会有44.8吨重。

When the concrete is transported to the arrival station, it is necessary to immediately wash off the concrete with hard bottom by running water, so as to maintain the capacity of the barrel and maximize the profit. At present, the volume of mixer trucks in China is from 3 to 18 cubic meters. A 12 square meter idle mixer truck weighs about 16 tons. If all are filled, the net weight of one cubic meter of concrete is calculated according to 2.4 tons, and the whole vehicle will weigh 44.8 tons.

那样的吨数实际上非常容易发生一些侧滑这类的事故。因此我国对搅拌车的时速开展了限定：很大车速不可以超出50/钟头。但是，因为商业服务的迫使，很多商人生产制造了许多远超吨数规范的搅拌车。这种违反规定车不但会对路面导致一定的危害，并且还提升了车祸事故的隐患。

In fact, safety accidents such as side slip are very easy to occur at such tonnage. Therefore, the speed of the mixer truck is limited in China: the speed cannot exceed 50km / h. However, due to the pressure of commercial services, many merchants produced and manufactured many mixer trucks far exceeding the national tonnage specifications. Such vehicles violating the regulations will not only cause certain harm to the road surface, but also enhance the safety potential of traffic accidents.
