Cement: powder hydraulic inorganic cementing material. Mud can be hardened in air or water after being mixed with water, and can firmly bond sand, stone and other materials together.
A mixture of early lime and pozzolan and modern lime pozzolan cement? Similarly, the concrete made of crushed stone cemented with it not only has high strength after hardening, but also can resist the erosion of fresh water or salt water. For a long time, as an important cementing material, it has been widely used in civil engineering, water conservancy, national defense and other projects.
Naming principle of cement:
The naming of cement is based on the main hydraulic minerals, mixed materials, uses and main characteristics of cement according to different categories, and strives to be concise and accurate. Abbreviations are allowed when the name is too long.
General cement is named after the name of the main hydraulic minerals of cement and the name of the admixture or other appropriate names.
Special cement is named after its special use, and can be labeled with different models.
Characteristic cement is named after the main hydraulic minerals of cement, which can be named according to different models or mixed materials.
Cement with active substances such as pozzolan or potential hydraulic materials as its main components can be named after active substances or with characteristic names, such as persulfate cement and lime pozzolan cement.
