Abstract

A method of making a structural component (and such a structural component) comprising mixing together wood pulp, water, bentonite clay, and calcium chloride and forming the mixture into the structural component.

What is claimed is: 
     
         1 . A load-bearing block comprising press cake, water, bentonite clay, and calcium chloride. 
     
     
         2 . The load-bearing block of  claim 1  consisting essentially of press cake, water, bentonite clay, and calcium chloride. 
     
     
         3 . The load-bearing block of  claim 1  consisting of wood pulp, water, bentonite clay, and calcium chloride. 
     
     
         4 . The load-bearing block of  claim 1  additionally comprising a wire screen. 
     
     
         5 . The load-bearing block of  claim 1  additionally comprising rebar. 
     
     
         6 . The load-bearing block of  claim 1  wherein the block is an interlocking block. 
     
     
         7 . The load-bearing block of  claim 1  additionally comprising one or both of borax and boric acid. 
     
     
         8 . The load-bearing block of  claim 7  consisting essentially of press cake, water, one or both of borax and boric acid, bentonite clay, and calcium chloride. 
     
     
         9 . The load-bearing block of  claim 1  wherein said bentonite clay comprises about 10% of said load-bearing block by volume. 
     
     
         10 . The load-bearing block of  claim 1  wherein said calcium chloride comprises about 10% of said structural component by volume. 
     
     
         11 . The load-bearing block of  claim 11  wherein said press cake comprises recycled paper or cardboard. 
     
     
         12 . A structure comprising a plurality of the load-bearing blocks of  claim 1 . 
     
     
         13 . A structure comprising a plurality of load-bearing blocks, each block comprising press water, bentonite clay, and calcium chloride. 
     
     
         14 . The structure of  claim 13 , each block consisting essentially of press cake, water, bentonite clay, and calcium chloride. 
     
     
         15 . The structure of  claim 13 , each block consisting of wood pulp, water, bentonite clay, and calcium chloride. 
     
     
         16 . The structure of  claim 13  additionally comprising a wire screen in one or more of said block. 
     
     
         17 . The structure of  claim 13  additionally comprising rebar in one or more of said blocks. 
     
     
         18 . The structure of  claim 13  wherein one or more of the blocks is an interlocking block. 
     
     
         19 . The structure of  claim 13 , each block additionally comprising one or both of borax and boric acid. 
     
     
         20 . The structure of  claim 19 , each block consisting essentially of press cake, water, one or both of borax and boric acid, bentonite clay, and calcium chloride. 
     
     
         21 . The structure of  claim 20  wherein said press cake comprises recycled paper or cardboard.
