Where l is the thermal conductivity of a porous ceramic body l o is the thermal conductivity of a porous free ceramic body p is the volume fraction of porous and n is a constant.
Thermal conductivity of ceramic floor tiles.
In all the samples the experimental values of thermal conductivity are always lower than the theoretical ones and are coherent with the value of thermal conductivity reported in the standard uni en iso 10456 for ceramic tiles with density of 2 3 g cm 3 1 3 w m k.
Floor tile materials studied in this work presented a wide range of thermal conductivities framed by the low thermal conductivity of vinyl below 0 20 w m 1 k 1 and the upper limit of granite 4 w m 1 k 1.
Both ceramic and porcelain tiled floors have a high level of thermal conductivity which means when used with an underfloor heating system they heat up faster and retain this heat for longer.
This ceramic tile for being clearer it can be dazzling under direct insulation.
Due to the.
For this test considering the homogeneous sample it is possible to determine the thermal conductivity through the equation 1 where λ is the conductivity w m k.
The theoretical values determined on the basis of total porosity by astm c329.
On the other hand the thermal conductivity of ceramic tiles ranges from 0 6 to 1 7 wm 1 k 1 and correlates more with density porosity and less with moisture content 7.
Sugawara and yoshizawa 1962 measured the thermal conductivity of a ceramic tile at 70 c.
