API RP 10B-5 (R2020) PDF

This standard provides the methods for the testing of well cement formulations to determine the dimension changes during the curing process (cement hydration) at atmospheric pressure only. This is a base document, because under real well cementing conditions shrinkage and expansion take place under pressure and different boundary conditions.

This edition of API RP 10B-5 is the identical national adoption of ISO 10426-5, Petroleum and natural gas industries-Cements and materials for well cementing- Part 5: Determination of shrinkage and expansion of well cement formulations at atmospheric pressure.
