混凝土攪拌機邊攪拌邊運輸時禁止加水

對于混凝土,很多人都會隨時攪拌,防止干結,要是進行長期運輸的話就需要使用混凝土攪拌車,一邊攪拌一邊運輸,在使用攪拌車的時候一個禁止事項就是攪拌車內禁止加水,為什么?
For concrete, many people will mix it at any time to prevent it from drying. If it is transported for a long time, it needs to use a concrete mixer truck to transport it while mixing. When using a mixer truck, one of the prohibitions is that it is forbidden to add water in the mixer truck. Why?
因為商品混凝土在混凝土攪拌車里面的時候,還是屬于半成品,在車里面不停的攪拌是為了保證混凝土在動態的情況下保持出廠的均勻性,混凝土在動態的時候比靜態的時候坍落度損失較小。
Because the commercial concrete is still a semi-finished product when it is in the concrete mixer truck, the continuous mixing in the truck is to ensure that the concrete maintains the uniformity of the factory under dynamic conditions, and the slump loss of the concrete under dynamic conditions is smaller than that under static conditions.
禁止加水的都是商品混凝土在出廠后的要求,因為混凝土重要的一點是要保證其強度,混凝土的強度是在水泥用量一定時候,水越多,強度越低。因此,在混凝土攪拌車中禁止加水。
What is forbidden to add water is the requirement of commercial concrete after leaving the factory, because the important point of concrete is to ensure its strength. The strength of concrete is that when the amount of cement is certain, the more water, the lower the strength. Therefore, it is forbidden to add water in the concrete mixer.
所以自動混凝土攪拌機禁止加水,加水可能會改變混凝土的性能,一旦混凝土中混入很多水那么會變成稀泥,不僅混凝土的強度變低而且還會弄得慢車都是稀泥,不好清理。
Therefore, it is forbidden to add water to the automatic concrete mixer. Adding water may change the performance of the concrete. Once a lot of water is mixed into the concrete, it will become slime, which will not only reduce the strength of the concrete, but also make the slow car become slime, which is difficult to clean up.

加水結果:影響混凝土的密實性,進而影響混凝土的強度。
The result of adding water: it will affect the compactness of concrete, and then the strength of concrete.
禁止原因:
Reason for prohibition:
(1)當用同一品種及相同強度等級的水泥時,混凝土的強度等級主要取決于水灰比;
(1) When the cement of the same type and strength grade is used, the strength grade of concrete mainly depends on the water cement ratio;
(2)為了獲得混凝土必要的流動性,保證澆灌質量,常需要較多的水,也就增大了水灰比;(備注:因為水泥水化時所需要的結合水,一般只占水泥重量的25%左右)
(2) In order to obtain the necessary fluidity of concrete and ensure the pouring quality, more water is often required, which increases the water cement ratio; (Note: the combined water required for cement hydration generally accounts for only about 25% of the cement weight)
(3)當水泥水化后,多余的水分就殘留在混凝土中,形成水泡或蒸發后形成氣孔,減少了混凝土抵抗荷載的實際有效斷面,在荷載的作用下,可能在空隙周圍產生應力集中。
(3) When the cement is hydrated, the excess water will remain in the concrete to form bubbles or pores after evaporation, which reduces the actual effective section of the concrete to resist the load. Under the action of the load, stress concentration may occur around the voids.
(4)在水泥強度等級相同的情況下,水灰比越小,水泥石強度越高,與骨料黏結力也就越大,混凝土強度就越高。(備注:水泥石就是水泥漿液干硬后形成的塊體。)
(4) With the same cement strength grade, the smaller the water cement ratio, the higher the strength of the cement stone, the greater the adhesion with the aggregate, and the higher the strength of the concrete. (Note: cement stone is the block formed after the cement slurry is dried and hardened.)
(5)控制水灰比及水泥用量,是決定混凝土密實的關鍵主要因素。
(5) Controlling water cement ratio and cement dosage is the key factor to determine the compactness of concrete.
(6)混凝土的強度主要取決于水泥石的強度及骨料表面的黏結強度,而水泥石的強度及其與骨料的黏結強度又與水泥的強度等級、水灰比及骨料的性質有密切關系。
(6) The strength of concrete mainly depends on the strength of cement stone and the bonding strength of aggregate surface, and the strength of cement stone and its bonding strength with aggregate are closely related to the strength grade of cement, water cement ratio and the properties of aggregate.
