載滿混凝土的攪拌車走在路上，托著很大的滾桶，傳出轟隆轟隆的響聲，在行車的全過程中，后邊的滾桶也在不斷的旋轉，看起來還一些恐怖。那么為何攪拌桶要一直不斷地轉動呢？

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?

為何攪拌桶要一直不斷地轉動呢？那樣做主要是以便不許里邊承重的混凝土發(fā)生離析和終凝。那麼發(fā)生離析和初凝會導致哪些不良影響呢?當發(fā)生離析的情況下，混凝土里邊的水泥砂漿凝聚力量會大幅度降低，沒法爬取塊狀的砂礫石。

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.

而發(fā)生離析的混凝土，它的抗壓強度會降低，這樣一來對工程施工會導致不好危害。對于初凝，說白了，就是混凝土剛開始由軟發(fā)硬，而不可以再隨便地更改樣子。假如攪拌桶一直不運行，伴隨著時間的流逝，混凝土愈來愈硬，很后會變成一塊硬實的大磚塊，還如何使用呢?

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，是否攪拌桶運行的越是快就越好呢?回答是否認的。假如拌和得過快，在其中的水份會過多的揮發(fā)掉，進而造成品質上的一些難題。一般而言，拌和很適合的速度是每分10-30轉，那樣是較為有效率。如果是夏季的話，因為室外溫度自身就高，以便降低揮發(fā)，速率要再慢一點兒。

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.

當運送到到達站后，要立即地自來水沖洗掉早已發(fā)生硬底化的混凝土，便于維持桶內容量的利潤很大化。現(xiàn)階段而言，在我國的攪拌車容積從3-18立方米都是有。一輛12方的閑置的攪拌車大概重為16噸。假如所有放滿的話，一立方米混凝土的凈重依照2.4噸計算出來，整輛車就會有44.8噸重。

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.

那樣的噸數(shù)實際上非常容易發(fā)生一些側滑這類的事故。因此我國對攪拌車的時速開展了限定：很大車速不可以超出50/鐘頭。但是，因為商業(yè)服務的迫使，很多商人生產制造了許多遠超噸數(shù)規(guī)范的攪拌車。這種違反規(guī)定車不但會對路面導致一定的危害，并且還提升了車禍事故的隱患。

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.
