The concrete industry has undergone decades of development, and the mix design and production process have become relatively mature.
However, the current quality control of concrete still faces core difficulties – the quality of raw materials is uneven and fluctuates frequently.
If the mix ratio is not adjusted in a timely and accurate manner, it is easy to cause various quality problems.
For example, concrete mixtures are often blocked due to poor aggregate wrapping, segregation, bleeding, or excessive loss of slump over time; Fluctuations in raw materials may also result in substandard strength or large strength dispersion of concrete test blocks, leading to substandard engineering quality.
With the increasing efforts in environmental control, unstable raw material quality has become a norm in the industry.
Therefore, understanding the current status of raw materials, adapting production processes to fluctuations in raw materials, and improving concrete quality are of great practical significance.
