Multi-layered tile or block

Abstract

The present invention relates to a multi-layered tile or block comprising of at least three different layers wherein at least one layer comprises of a cementitious material, mixed with a filler and/or an aggregate.

1 . A multi-layered tile or block comprising of at least three different layers wherein at least one layer comprises of a cementitious material, mixed with a filler and/or an aggregate.  
   
   
       2 . A multi-layered tile or block as claimed in  claim 1 , wherein the cementitious material is hydraulic cement, refractory cement ceramic cement, starches, gums, cellulose or a combination thereof.  
   
   
       3 . A multi-layered tile or block as claimed in  claim 2 , wherein the hydraulic cement is white cement or grey cement or a combination of both.  
   
   
       4 . A multi-layered tile or block as claimed in  claim 1 , wherein the cementitious material is in a proportion of utmost 50% of the total dry weight of all the layers.  
   
   
       5 . A multi-layered tile or block as claimed in  claim 1 , wherein the cementitious material is in a proportion of 25-35% of the total dry weight of all the layers.  
   
   
       6 . A multi-layered tile or block as claimed in  claim 1 , wherein the filler and/or aggregate are natural minerals or man made materials or a combination of both.  
   
   
       7 . A multi-layered tile or block as claimed in  claim 6  wherein the natural minerals are marble, calcite, dolomite, talk, mica, granite, silicious stone, calciferous stone, basaltic stone, lime stone, quartz, feldspar, gypsum, selenite, asbestos or any mixture thereof.  
   
   
       8 . A multi-layered tile or block as claimed in  claim 6 , wherein the man made materials are broken waste ceramic, alumina, steatite, aluminosilicates, magnesite, silicon carbide, compounds of magnesium, compounds of zirconium, calcined or burnt clays, hydrated lime, bauxite, organic or inorganic polymerized materials, plaster of paris, ceramics including-vitrified and porous ceramic materials and mixtures thereof and ceramic process wastes or any mixture thereof.  
   
   
       9 . A multi-layered tile or block as claimed in  claim 1 , wherein at least one layer is of ceramic.  
   
   
       10 . A multi-layered tile or block as claimed in  claim 1 , wherein an exposed surface of the tile is decorative.
