With the development of modern construction technology and the continuous expansion of engineering scale, the engineering field has put forward higher requirements for the performance of concrete.
As an important component of concrete, the physical properties, chemical composition, and harmful substance content of sand and gravel aggregates will have a significant impact on the strength, workability, durability, and other aspects of concrete.
Therefore, in the field of engineering construction, it is not only necessary to have a deep understanding of the impact mechanism of sand and gravel aggregates on concrete performance, but also to find scientific and rigorous quality control measures to ensure that the quality of sand and gravel aggregates meets engineering requirements.
