A grout prism is not really a cube or beam, and it's definitely not a cylinder, so how do I enter one?
The testing machine only cares about specimen type, which is the geometry (i.e., cylinder, cube, beam, etc.), and test type (i.e., compression, tensile split, flexural, etc.). The specimen type is generic in that it is independent of material type (i.e., concrete, mortar, grout, shotcrete, etc.). ForneyVault has not yet implemented material types (coming soon!).
What this means is that a masonry grout prism is typically entered as a cube specimen type. In ForneyVault, a cube is a three-dimensional rectangle that has length, width, and depth. A beam also has length, width, and depth, but a beam is intended for flexural testing, whereas a cube is intended for compression.
Therefore, when you create default specimens, you can create a cube that is named something like, “Masonry Grout Prism,” and then provide the typical nominal dimensions. Keep in mind that “depth” is typically the vertical dimension as oriented for testing. In other words, “depth” could be though of as the height.
When you create your grout prism set, you select a “Cube” specimen type, then choose the “Masonry Grout Prism” default specimen.
