Scope
This document presents the methodological principles of the chemical shrinkage test for cement slurries, describes the test method, and specifies the repeatability and reproducibility of the test laboratory and equipment, materials, and methods.
This document is applicable to the chemical shrinkage test for silicate cement slurries.
Note: The chemical shrinkage test method for cement slurries is divided into the absolute volume method and the apparent volume method.
