ASTM C806

Restrained Expansion of Expansive Cement Mortar

Applicability: ASTM C806 primarily focuses on determining the length changes of expansive cement mortar under restraint, by evaluating the restrained expansion and potential shrinkage of expansive cement mortars caused by the internal forces developed during cement hydration.

Purpose: The primary purpose is to assess how these materials perform under conditions of controlled restraint, simulating real-world scenarios where mortar might be constrained within a structure.
