Abstract
|
|
|
|
A ceramic floor with improved thermal conductivity and efficiency has been developed in this study. The new ceramic floor minimizes the shrinkage rate to below 0.07% and shows almost no cleavage. There is no need to repaire the ceramic floor because its bottom surface is flat. It especially shows an excellent perfomance in the test of a compressive strength (300 ㎏/㎠ based on 28 days), a flexural strength (64 ㎏/㎠ based on 28 days), and a convenient pressing. It is lighter than the present floor and it is expected to be applicable for a self-leveling ceramic motar in the residences and apartments. It shows an excellent character in the thermal conductivity and other physical properties compare to the present cement mortar.
