Decorative concrete with uniform surface and method of forming the same

Abstract

A decorative concrete with a very uniform finish surface and a method of fabricating the same is disclosed. A concrete mixture is poured over a subgrade which defines an exposed surface. The exposed surface is finished with any of several techniques, and the surface is then worked with an abrasive material, and additional techniques are used to color and seal the concrete.

         16 . A method of forming a decorative concrete slab having a highly uniform exposed surface, comprising:
 pouring a concrete mixture over a subgrade, the concrete mixture defining an exposed top surface when poured;   finishing the exposed top surface;   allowing the concrete to harden; and   applying an abrasive upon the exposed top surface to reduce any nonuniformity of the exposed top surface.   
     
     
         17 . The method of  claim 16 , further comprising the steps of washing the surface film, curing the slab with water, and power washing the slab. 
     
     
         18 . The method of  claim 16 , further comprising sand blasting the exposed top surface after allowing the concrete to harden. 
     
     
         19 . The method of  claim 16 , further comprising acid washing the exposed top surface after allowing the concrete to harden. 
     
     
         20 . The method of  claim 16 , wherein finishing the exposed surface comprises applying aggregate. 
     
     
         21 . The method of  claim 16 , wherein the abrasive is sandpaper. 
     
     
         22 . The method of  claim 16 , wherein applying the abrasive is done with a machine. 
     
     
         23 . The method of  claim 16 , wherein finishing the exposed surface comprises applying fine sand. 
     
     
         24 . The method of  claim 16 , wherein finishing the exposed surface comprises applying a mixture of fine sand and aggregate. 
     
     
         25 . The method of  claim 16  further comprising the step of applying a stain after applying the abrasive to the exposed top surface.
