混凝土的水灰比对混凝土的强度影响很大。在机械化搅拌过程中,精确地控制加水量,对于保证混凝土质量,稳定生产过程是非常重要的。但在搅拌实践中,由于混凝土配合比控制精度低,生产过程中加水量不能随机调整,水灰比偏离设计值,造成质量不稳定,强度波动达设计强度的10～30%。其中砂子含水率的大幅度变动和不能针对这种变动随机修正用水量是一个关键性因素。目
The water cement ratio of concrete has a great influence on the strength of concrete. In the mechanized mixing process, precise control of the amount of water added is very important for ensuring the quality of concrete and stabilizing the production process. However, in the practice of mixing, due to the low precision of concrete mix ratio control, the amount of water added in the production process cannot be adjusted randomly, and the water-cement ratio deviates from the design value, resulting in unstable quality and intensity fluctuations of 10% to 30% of design strength. The significant change in the moisture content of the sand and the inability to randomly adjust the water consumption for this change are a key factor. Head
