RAM Concept uses materials as part of the input and the results. You specify concrete mixes and post-tensioning systems as part of the input and RAM Concept reports reinforcement bar requirements as part of the results.

You can use the materials provided or create your own. For example, you might want to redesign the floor with the actual tested strength of the concrete poured on site. In this case, you would create a new concrete mix defined with that strength.

You can delete any of the materials that you find are unnecessary.
