With the increasing scarcity of natural sand resources and the continuous improvement of environmental protection requirements in construction, machine-made sand has gradually become an important raw material for concrete production.
However, in the production process of mechanism sand, there are common problems such as excessive particle edges, rough surface, and discontinuous gradation, which lead to high water demand and poor workability of concrete, as well as significant strength fluctuations.
At the same time, cement, as the main cementitious material in concrete, generates a large amount of carbon dioxide emissions during its production process, causing serious environmental burden.
