GB/T 176 - 2008 Specifies the chemical analysis process of cement. This standard covers the determination of various chemical components in cement, such as calcium oxidation, silica, etc. It details various analytical methods, including benchmark methods and substitute methods, and specifies the required equipment, such as Balance accuracy, Burette specifications. There are strict requirements for sample prepative, reagent configuration and analysis steps to ensure accurate and reliable results. With this standard, the chemical composition of cement can be accurately grasped, providing key data support for cement production quality control, performance research and engineering applications. It is widely used in cement production, Quality control and related scientific research fields.
