小型混凝土自動攪拌車對混凝土質量的影響主要在計量和攪拌工藝的方面。生產的時候,注意觀察計量的誤差,對過沖量的調整,以及投料過程的殘余量的把握,確保計量的精度合乎要求。需要特別注意的有以下方面:
The influence of small automatic concrete mixer on concrete quality mainly lies in the measurement and mixing technology. During production, pay attention to observe the measurement error, adjust the overshoot, and grasp the residual quantity in the feeding process, so as to ensure that the measurement accuracy meets the requirements. Special attention should be paid to the following aspects:
1、外加材料對混凝土的影響很大,有一些的用量很小,在這一方面要特別注意其計量的精 確性。
1. Additional materials have a great influence on concrete, some of which are used in a small amount. In this regard, we should pay special attention to the accuracy of measurement.

2、混凝土的坍落度對混凝土的性能與質量有直接的影響,但是由于砂石的含水率不能保證穩定。這樣,如果設備不能對砂石的含水率進行自動調整,就需要不斷的對砂石的干濕程度和出料口的混凝土的塌落度進行觀察和把握,必要時對砂和水的配比進行調整,以確保塌落度不出現較大偏差。
2. The slump of concrete has a direct impact on the performance and quality of concrete, but the moisture content of sand and gravel can not guarantee stability. In this way, if the equipment can not automatically adjust the moisture content of sand and gravel, it is necessary to continuously observe and grasp the dry and wet degree of sand and gravel and the slump of concrete at the outlet, and adjust the ratio of sand and water when necessary, so as to ensure that there is no large deviation in the slump.
3、攪拌的工藝方面主要是根據所生產的混凝土的特點對投料時序和攪拌、放出的時間進行調整,以確?;炷粱旌喜嚢杈鶆?,達到設計的要求和性能。當生產的混凝土中摻用摻合料時,攪拌時間應該適當延長。干摻時,粉煤灰的混凝土的攪拌時間要比普通混凝土延長10-30秒,其他摻合料的混凝土延長30-60秒。
3. Mixing technology is mainly based on the characteristics of the production of concrete feeding timing and mixing, release time adjustment, to ensure that the concrete mixing and mixing evenly, to meet the design requirements and performance. When admixtures are used in the concrete, the mixing time should be extended appropriately. When dry mixing, the mixing time of fly ash concrete is 10-30 seconds longer than that of ordinary concrete, and other admixtures concrete is 30-60 seconds longer.
