ASTM C476 – Standard Specification for Grout for Masonry


This specification covers two types of grout, fine and coarse grout, for use in the construction of masonry structures.

Each type (fine and coarse) is further classified as conventional grout (requiring mechanical consolidation by puddling or vibration when placed) and self-consolidating grout (not requiring mechanical consolidation when placed).

Conventional grout is specified by (1) proportions or (2) strength requirements. Self-consolidating grout is specified by strength requirements.
