Abstract

A structural element is disclosed that is shaped as at least one of a plank, a post, and a board. The structural element comprises a fiber reinforced ceramic cement body having at least an outer layer having a hardness and ductility suitable for receiving and holding a nail. Also disclosed is a structural element having a body at least partially shaped as at least one of a plank, a post, and a board. The body comprises at least an internal layer comprising fiber reinforced ceramic cement, and at least an external layer comprising a material suitable for receiving and holding a nail.

Claims

exact text as granted — not AI-modified
1 . A structural element shaped as at least one of a plank, a post, and a board, comprising:
 a fiber reinforced ceramic cement body having at least an outer layer having a hardness and ductility suitable for receiving and holding a nail.   
     
     
         2 . The structural element of  claim 1  in which the fiber reinforced ceramic cement body comprises magnesium oxide and a binder. 
     
     
         3 . The structural element of  claim 2  in which the binder comprises magnesium chloride. 
     
     
         4 . The structural element of  claim 1  in which at least the outer layer of the fiber reinforced ceramic cement body comprises a filler. 
     
     
         5 . The structural material of  claim 3  in which the filler comprises at least one of sawdust, straw, wood fiber, and particulate matter. 
     
     
         6 . The structural material of  claim 4  in which at least the outer layer comprises less than or equal to 30% by weight of filler. 
     
     
         7 . The structural material of  claim 4  in which the filler comprises a fine powder between 120 and 270 mesh. 
     
     
         8 . The structural element of  claim 1  in which the outer layer is water resistant. 
     
     
         9 . The structural element of  claim 1 , further comprising a core. 
     
     
         10 . The structural element of  claim 9  in which the core is a hollow core. 
     
     
         11 . The structural element of  claim 10  in which the hollow core is formed within a tube of material. 
     
     
         12 . The structural element of  claim 9  in which the core comprises at least one of ceramic cement, wood, plant material, bamboo, paper, plastic fragments, and particulates. 
     
     
         13 . The structural element of  claim 1  in which the fiber reinforced ceramic cement body further comprises at least a fiber reinforced layer and a ceramic cement layer. 
     
     
         14 . The structural element of  claim 1  in which the fiber reinforced ceramic cement body comprises at least one of fiberglass and hemp. 
     
     
         15 . The structural element of  claim 1  in which the outer layer comprises at least one pigment. 
     
     
         16 . The structural element of  claim 1  further comprising a protective overlayer comprising at least one of plastic, rubber, hemp, and fiberglass. 
     
     
         17 . The structural element of  claim 1  in which the fiber reinforced ceramic cement body is cylindrical. 
     
     
         18 . The structural element of  claim 17  in which fiber within the fiber re-inforced ceramic cement body is formed in one or more tubular layers. 
     
     
         19 . A structural element having a body at least partially shaped as at least one of a plank, a post, and a board, the body comprising:
 at least an internal layer comprising fiber reinforced ceramic cement; and   at least an external layer comprising a material suitable for receiving and holding a nail.   
     
     
         20 . The structural element of  claim 19  in which the external layer comprises ceramic cement. 
     
     
         21 . The structural element of  claim 20  in which at least the external layer comprises a filler. 
     
     
         22 . The structural material of  claim 21  in which the filler comprises at least one of sawdust, straw, wood fiber, and particulate matter. 
     
     
         23 . The structural material of  claim 21  in which at least the ceramic cement comprises less than or equal to 30% by weight of filler. 
     
     
         24 . The structural material of  claim 21  in which the filler comprises a fine powder between 120 and 270 mesh. 
     
     
         25 . The structural element of  claim 19  in which the external layer has a hardness and ductility suitable for receiving and holding a nail. 
     
     
         26 . The structural element of  claims 19  in which the fiber reinforced ceramic cement comprises magnesium oxide and a binder. 
     
     
         27 . The structural element of  claim 26  in which the binder comprises magnesium chloride. 
     
     
         28 . The structural element of  claim 19  in which the external layer is water resistant. 
     
     
         29 . The structural element of  claim 19 , further comprising a core. 
     
     
         30 . The structural element of  claim 29  in which the core is a hollow core. 
     
     
         31 . The structural element of  claim 30  in which the hollow core is formed within a tube of material. 
     
     
         32 . The structural element of  claim 29  in which the core comprises at least one of ceramic cement, wood, plant material, bamboo, paper, plastic fragments, and particulates
