The synthesis of a new glass-ceramic obtained by sinter-crystallization has been investigated
by using soda-lime-silicate glass waste and fly ashes from a coal power thermal station
located in Andorra (Teruel, Spain). An original glass as frit with composition of 50wt%
recycled soda-lime glass, 25wt% bottom ash, 15wt% fly ash and 10wt% CaCO3
has
been melted. After sinter-crystallization at 850ºC, it has precipitated two main crystalline
phases: sodium anorthite and the hedenbergite. The linear shrinkage is 1/3 of the value
of conventional porcelainized stoneware and the water absorption of this glass-ceramic is
similar to a conventional porcelainized stoneware tile (less than 1wt%), being the apparent
density slightly higher than this type of tiles (2.6g/cm3
instead of 2.4g/cm3
). Flexural
strength is near twice than porcelainized stoneware (around 950kg/cm2
instead of 550kg/
cm2
) (95MPa in the new glass- ceramic with respect to 55MPa for the above mentioned as
reference material). [-]
