Frost resistance of ceramic floor tiles : A prenormative study
In this work, the mechanisms of floor damaging are studied on the basis of physical characteristics, mechanical fatigue tests and Finite Element calculation. It has been demonstrated that the volume expansion associated with ice formation, even if deleterious at a micronic scale, is not able alone to induce the characteristic flaws observed outdoor. Therefore, additional stresses associated with laying are very likely involved in the damaging mechanism. Such stresses (compressive or tensile according to the season) are mainly due to: 1) the thermal mismatch between the tile and the basement. 2) the impediment of any free expansion due to the surrounding construction. The major role of those macroscopic stresses and their related effect has been highlighted both by mechanical fatigue tests (static and cyclic loading) and by frost-thawing cycles performed on tiles embedded into a stiff concrete structure. According to those tests, outdoor flaws have been effectively reproduced in laboratory.
