سؤال
Concrete is a combination of cement, sand or other fine aggregates, and a coarse aggregate ranging in size from 19 to 25 mm. People use concrete in a wide range of construction applications. Some applications of the different types of cement include: Plastering, masonry construction, pointing, and other purposes.
سؤال
· The initial step in cement manufacturing is the crushing of raw materials. These materials typically include limestone, clay, or shale. The crushing process takes place in a tube mill, where steel balls are present. Depending on the desired product, this process can be carried out in either wet or dry conditions.
سؤال
· Gypsum: Gypsum (CaSO4·2H2O) is typically added to the cement manufacturing process as a setting regulator. It helps to control the setting time of cement and prevents flash setting, ensuring that the cement hardens gradually when mixed with water. Gypsum also improves the workability of the cement paste.
