Application Summary AI generated
This standard specifies a laboratory test method for measuring the chemical shrinkage of cement paste, which is the volume reduction that occurs during cement hydration. It is applied in the construction materials industry for quality control and performance evaluation of cement, particularly in the formulation of concrete and grouting materials. The method is used by testing laboratories and cement manufacturers to assess early-age shrinkage behavior, which is critical for predicting cracking risks in structures.
