What Is Moh's Stiffness Test
The Mohs Hardness Test is a simple field method used to determine how resistant a concrete surface is to scratching. In practical terms, it tells you how hard or soft the top layer of the concrete is. The test is based on a scale from 1 to 10, where each level represents a material with known hardness. When applied to concrete floors, it does not measure the overall strength of the slab or its structural capacity. Instead, it focuses only on the surface layer.
A higher Mohs value means the surface is more resistant to scratching and generally denser, while a lower value indicates a softer and weaker surface.
The Mohs hardness table is a scale from 1 to 10 that ranks materials by scratch resistance, from soft (talc) to very hard (diamond). It is used to quickly compare and estimate material hardness.
