The particle size, shape, and strength characteristics of aggregates have a direct impact on the compressive strength of concrete.
Choosing aggregates with good physical and chemical stability is an important means to improve the strength of concrete.
Strict control over the content of various substances in both coarse and fine aggregates is essential, especially the chloride ion content.
Excessive chloride ion content, such as using sea sand, can have a strong corrosive effect on steel bars, which not only seriously threatens the durability of concrete, but also weakens its structural integrity.
Therefore, ensuring the high quality of aggregates plays a crucial role in ensuring the compressive strength of concrete.
