Composite for building material, and method of manufacturing building material using the same

Abstract

To provide a composite for a building material capable of manufacturing a building material that is harmless to living environment and global environment and can be recycled. The composite for a building material contains diatomaceous earth, waste lumber, and inorganic hardener, or further contains field earth, and, as necessary, contains used paper and/or crushed pieces of used tatami mat and used tile, and crushed earth. The composite for a building material is prepared by homogeneously mixing the components, and then the building material is manufactured by molding and curing the composite. The manufactured building material has a high humidity conditioning property as in the case of the conventional mud wall made of coarse clay, and is easily recycled by being crushed. Moreover, this building material does not cause hypersensitiveness to chemical substances because it produces no chemical substances, and has a feel of earth so that earthen walls and flower beds made by using this building material integrate well with an appearance of ancient city and are in harmony with beautiful appearance of houses properly.

1 . A composite for a building material comprising: 
 diatomaceous earth;    waste lumber; and    an inorganic hardener selected from the group consisting of:    hardener for cement mud wall; hardener for silicate mud wall; and hardener for water-glass mud wall.    
     
     
         2 . The composite for a building material according to  claim 1 , wherein said diatomaceous earth is 10 to 50 percent by weight, based on a total weight of the composite; said waste lumber is 5 to 30 percent by weight, based on the total weight of the composite; and said inorganic hardener is 10 to 80 percent by weight, based on the total weight of the composite.  
     
     
         3 . The composite for a building material according to  claim 1 , further comprising field earth.  
     
     
         4 . The composite for a building material according to  claim 3 , wherein said field earth is 5 to 40 percent by weight, based on a total weight of the composite.  
     
     
         5 . The composite for a building material according to  claim 1 , wherein said composite further comprises at least one substance selected from the group consisting of: used paper; crushed pieces of used tatami mat ; crushed pieces of used tile; and crushed earth.  
     
     
         6 . The composite for a building material according to  claim 5 , wherein when at least one of said used paper and said crushed earth is present, a content of said at least one of said used paper and said crushed earth is 10 to 30 percent by weight, based on a total weight of the composite.  
     
     
         7 . A method of manufacturing a building material, comprising: 
 homogeneously mixing diatomaceous earth, waste lumber, and water, to form a homogeneous mixture;    mixing an inorganic hardener with said homogeneous mixture, to produce a composite for a building material;    molding the composite for a building material; and    curing the molded composite for a building material to produce said building materia.    
     
     
         8 . A method of manufacturing a building material, comprising: 
 homogeneously mixing diatomaceous earth, waste lumber, field earth, and water, to form a homogeneous mixture;    mixing an inorganic hardener with said homogeneous mixture, to produce a composite for a building material;    molding the composite for a building material; and    curing the molded composite for a building material, to produce said building material.    
     
     
         9 . The method of manufacturing a building material according to  claim 7  further comprising mixing at least one of: used paper; crushed pieces of used tatami mat; crushed pieces of used tile; and crushed earth with said homogeneous mixture.  
     
     
         10 . The method of manufacturing a building material according to  claim 7 , wherein said molding comprises slip casting of said composite for a building material.  
     
     
         11 . The method of manufacturing a building material according to  claim 7 , wherein said molding comprises extrusion molding of said composite for a building material.
