Dilatometric Analysis of Ceramic Roof Tiles for Determining Irreversible Moisture Expansion

Original language description

Porous clay ceramic materials are subject to an ageing process which leads to moisture expansion. The irreversible moisture expansion value is determined with the use of time-consuming standard tests that require samples 20 cm in length. An advantage ofa method based on dilatometric measurement is that samples 2.5 cm in size can be measured. Using this method, we determined the irreversible moisture expansion values of samples of historical roof tiles of various ages. The procedure analyses the courseand the shape of the curves and reveals whether the volume changes result from the moisture expansion process. Rehydrated water is evolved within the interval 150 ? 500 °C. In addition, the correlation between the mineralogical composition and the irreversible expansion value has been studied. Materials containing mullite fired at temperatures above 1000 °C show low values, while samples with high porosity and containing no mullite fired at temperatures below 1000 °C show high values. Ma
