ASTM C109/C109M — Compressive Strength of Hydraulic Cement Mortar Cube Mold
This triple-gang silicone mold produces three 50 mm × 50 mm × 50 mm (2 × 2 × 2 in.) cube specimens in a single pour, as required by ASTM C109/C109M for compressive strength testing of hydraulic cement mortars. The test result is the average of compressive strength tests of three cubes molded from a single batch of mortar and tested at the same age Verified Market Reports — making a 3-cavity gang mold the natural, efficient choice for complete batch testing.
Suitable materials: Portland cement mortar · Blended cement mortars · Masonry cements · Geopolymer mortars · Supplementary cementitious materials (SCM) · Fly ash and slag blends · Lime mortars · Tile setting mortars · Repair mortars
Related standards and applications: ASTM C109/C109M (primary) · ISO 679:2009 (international equivalent — same 50mm cube geometry) · EN 196-1 (European cement mortar standard) · BS EN 1015 · ASTM C348 (flexural companion — use with our C348 prism mold) · ASTM C349 (compressive strength from prism halves)
Note: The 50 mm cube specimen is also used in research on tile adhesives, repair mortars, and geopolymer binders where ASTM C109 is referenced or adapted. The same mold is used across cement qualification, SCM research, and DOT compliance testing programs.

The molds are reusable.
However, silicone molds have a finite lifespan when using polyurethane or epoxy resins.
Applying a non-silicone based release agent and letting the mold rest for a few days after each use will increase the lifespan of the silicone molds.
