You must have noticed those minute or even prominent hair line cracks on the ceramic tiles of your flooring. Some tiles also seem to break away at the ends after few years’ time. These cracks and breakages are a result of unsupported or soft layers or maybe they have not been fixed to the walls or flooring properly for support.
It is to be noted that floors are more prone to damage when it comes to ceramic tiles, as compared to walls because of falling objects and greater pressure of the furniture and human weights! The impact of resistance has been defined as per various standards as a measure for testing the strength, stamina and life of the ceramic tiles. The co-efficient of restitution is a measure used to quantify the impact of resistance. Defined by Standard EN 1441, the co-efficient of restitution helps to find out how strong the ceramic tile is with the help of a steel ball thrown from a height on the tile and see if it breaks and if it does, what is the breaking pattern.
Conditions for measuring the co-efficient of Restitution
Before the test can begin, below are the conditions that need to be set for successful and noise free testing of strength of the ceramic tiles.
- The piece of tile to be tested from the sample needs to be fixed on a concrete slab with adhesive or glue.
- Only when the glue has hardened a steel ball of 19 mm in diameter is dropped on it from a height of 1 m.
- The time differences are now captured between the first and second impact on the tile.
If the ceramic tile survives, it means there is no energy loss and there is no damage on the tile and you can purchase it without any doubt! One of the key things to consider in ceramic tiles is their strength to bear the impact of falling objects and the pressure of heavy furniture. In this case, where there is no energy loss, it mean the co-efficient of restitution is valued at 1. The ceramic tiles with co-efficient of restitution at 0.5 mean it will develop minor hair line cracks and slight breakages and that it will be less strong than the previous one.
It is always advisable to consult a leading manufacturer of ceramic tiles so that you get quality tested ceramic tiles with a high co-efficient of restitution so that they stand the test of time. Before finalising check for the certification details and magnitudes of dimensionless measure to validate the quality and strength of the ceramic tiles.
Not only is the interior beauty of your rooms or office important, it is also equally important to make sure that the tiles are able to endure the weight and pressure of the furniture and other objects. Most important for the ceramic tiles is the impact of falling objects and the height from which the object falls as the energy and pressure exerted on the ceramic tiles increases. The glazed tiles or the ones which are porous are easily affected by pointed objects compared to the unglazed vitrified ones.
