What does “modulus of rupture” measure in tile?

The modulus of rupture measures the flexural strength of a tile material, which is crucial in assessing how much stress a tile can endure before breaking when subjected to bending or flexing forces. This property indicates the tile's ability to withstand loads without failing, which is especially important in applications where tiles are subjected to forces, such as foot traffic or furniture placement.

Understanding the modulus of rupture helps contractors and designers choose the right tile for specific applications, ensuring that it can handle expected stresses without cracking or damaging the material. Flexural strength is a key performance criterion in tile manufacturing, influencing not only durability but also the overall longevity and effectiveness of tiled surfaces in various settings.
