Cement is the world's most widely used man-made material and an essential component of urbanization. Global cement production is projected to reach 4.3 billion tons in 2021, with 2.36 billion tons produced in China alone, accounts for over 50 % of the world's total cement production [1], [2].However, it is a high-resource-consuming and high-emission …
C 3 A is also a major contributor to portland cement's heat of hydration. Type III cement, which is specified in scenarios where high early strength or increased heat of hydration is desirable, allows a relatively high C 3 A content of up to 15%. Lower heat of hydration. Conversely, Type IV cement, which is specified when low heat of ...
Step 3: Fine Grinding. After the raw material batching is completed, cement raw meals (calcareous raw materials, clayey raw materials, and a small number of corrective materials) need to be further ground by raw mills to realize a certain fineness, appropriate chemical composition, and uniform structure so that they can meet the calcination requirements of various cement kilns.
