[0002] Cement is a powdery hydraulic inorganic gelling material, which becomes a slurry after adding water and stirring. It can harden in the air or harden better in water, and can firmly bond sand, stone and other materials together. The usual cement testing requires chemical analysis and physical properties. Chemical analysis includes the content of elements such as silicon, iron, calcium, magnesium, aluminum, and physical properties such as strength, specific surface area, loss on ignition, stability, fluidity, etc.
