Grout Sample Box
Alternative Method
- Proven by tests to yield comparable compressive strength values to samples cast by traditional method regardless of CMU moisture content.
- Consistent, identical prism geometry is created with every set of samples.
- Engineered slotted corrugation retains moisture while closely simulating CMU absorption rate.
- Performs as mold and transport/shipping container in one.
- Saves money, time, labor and space.
- Assembles easily, ships and stores flat.
- Yields an additional specimen as a reserve
- Conforms to ASTM Standards
- Refer to ASTM C1019-03 Note #6
- Patent #5942192
