全自動攪拌車攪拌時間不足會如何呢？實際上，如果全自動攪拌車攪拌時間不足，會導致混凝土失去均勻性，即混凝土中的水泥、沙子、石頭等原材料沒有充分混合，會導致混凝土強度降低、泌水率增加、空鼓和裂縫等問題。
What happens if the fully automatic mixer truck lacks mixing time? In fact, if the mixing time of the fully automatic mixer truck is insufficient, it will lead to the loss of uniformity of the concrete, that is, the raw materials such as cement, sand, and stones in the concrete are not fully mixed, which can lead to problems such as reduced concrete strength, increased bleeding rate, hollowing, and cracks.
如果混凝土強度不夠，可能會影響建筑物的承重能力和安全性。此外，攪拌時間不足還會影響混凝土的質量，使得不均勻的混凝土無法滿足施工要求，影響施工進度和建筑質量。
If the concrete strength is insufficient, it may affect the load-bearing capacity and safety of the building. In addition, insufficient mixing time can also affect the quality of concrete, making uneven concrete unable to meet construction requirements, affecting construction progress and building quality.
因此，需要根據混凝土的配合比、攪拌機型和攪拌速度等因素，合理設定攪拌時間，確保混凝土充分混合，保證施工質量和建筑物的安全性。
Therefore, it is necessary to set the mixing time reasonably based on factors such as the concrete mix ratio, mixing machine type, and mixing speed, to ensure sufficient mixing of concrete, construction quality, and building safety.
禁止無底線地縮短攪拌時間，建議一單一設定攪拌時間的方法。在國標GB/T14902—2012《預拌混凝土》中規定，混凝土在攪拌機中的攪拌時間，不應少于30s。國標GB50164—2011《混凝土質量控制標準》中規定，混凝土攪拌的短時間為60s，同時規定，雙臥軸強制式攪拌機，可在保證均勻的情況下適當縮短攪拌時間。根據上述兩個標準，混凝土攪拌時間不應少30s。
It is prohibited to shorten the mixing time without a bottom line. It is recommended to use a single method of setting the mixing time. According to the national standard GB/T14902-2012 "Ready Mixed Concrete", the mixing time of concrete in the mixer should not be less than 30 seconds. According to the national standard GB50164-2011 "Concrete Quality Control Standard", the short mixing time for concrete is 60 seconds. At the same time, it is stipulated that a dual horizontal shaft forced mixer can appropriately shorten the mixing time while ensuring uniformity. According to the above two standards, the concrete mixing time should not be less than 30 seconds.
很多通過不斷地減少攪拌時間來降低生產成本，有的攪拌時間僅為15s、20s，操作人員多是年輕人，通過減少攪拌時間，減少操作時間，降低工作強度，增加休息的時間，這是混凝土質量不斷劣化的一個原因。有些操作人員根據攪拌電流來推斷混凝土狀態，完全忽略了不同的混凝土需要的攪拌時間是不一樣的，所有混凝土都按一定的攪拌時間考慮，當攪拌電流偏高時，會采取加水措施。有些混凝土需要較長的攪拌時間，當設定攪拌時間較短時，攪拌電流偏高，一旦加水攪拌到電流合適，混凝土強度損失大，將造成工程事故。
Many people reduce production costs by continuously reducing mixing time, some of which only take 15s or 20s. The operators are mostly young people. By reducing mixing time, reducing operation time, reducing work intensity, and increasing rest time, this is one of the reasons for the continuous deterioration of concrete quality. Some operators infer the state of concrete based on the mixing current, completely ignoring that different types of concrete require different mixing times. All concrete is considered based on a certain mixing time, and when the mixing current is too high, water will be added. Some concrete requires a longer mixing time. When the mixing time is set to be short, the mixing current is too high. Once the water is added and the current is appropriate, the concrete strength will be lost greatly, which will cause engineering accidents.
實際生產中，影響攪拌時間的因素很多，強度等級不一樣的混凝土，需要的攪拌時間不一樣；混凝土稀稠不一樣，攪拌時間不一樣；同強度等級混凝土，施工部位不一樣，攪拌時間不一樣；同強度等級混凝土，外加劑不一樣，特別是加入粉劑后，攪拌時間不一樣；常溫混凝土與冬期攪拌時間不一樣；石子大小不一樣，攪拌時間不一樣；石子多少不一樣，攪拌時間不一樣。
In actual production, there are many factors that affect the mixing time. Concrete with different strength grades requires different mixing times; The thickness of concrete varies, and the mixing time varies; Concrete of the same strength grade has different construction sites and mixing times; For concrete of the same strength grade, the admixtures are different, especially after adding powder, the mixing time is different; The mixing time of normal temperature concrete is different from that of winter; The size of the stones varies, and the mixing time varies; The amount of stones varies, and the mixing time varies.
The mixing time should be set in the mix proportion sheet, with a single setting and priority given to the mixing time specified in the mix proportion sheet. Welcome to our website anytime http://www.www.boy7up.cn Consult for more matters!
