The physical properties of mechanism sand are significantly affected by its production process, and even after processing the same parent rock through different processes, its performance indicators vary greatly.
Mechanized sand has significant differences from natural sand in terms of grading, particle shape, and particle content below 0.
075mm.
In high-strength concrete, compared with natural sand, the use of machine-made sand is greatly restricted.
High strength concrete has stricter requirements for the parent rock, stone powder content, MB value, particle morphology, etc.
of machine-made sand.
