Pre-fabricated structural components strengthened with tensile reinforcements and method for production thereof

Abstract

The prefabricated structural components strengthened by tensile reinforcements, preferably metal inlays, containing binders and aggregates, wherein said binder is an alkali water glass, and the aggregates have a broad grain size distribution like aggregates added to reinforced concrete.

1 . Prefabricated structural components strengthened by tensile reinforcements containing cured binders and aggregates, characterized in that said binder is an alkali water glass, and the aggregates have a grain size distribution common for aggregates in reinforced concrete, wherein the components are mixed, introduced into a mold and cured at 100 to 150° C., followed by annealing the structural components at a temperature within a range of from 500 to 700° C.  
   
   
       2 . The structural components according to  claim 1 , characterized in that the metal inlays are in the form of rods, ropes and/or sheets.  
   
   
       3 . The structural components according to  claim 1 , characterized by being externally coated with a waterproof and weather-resistant protection layer.  
   
   
       4 . The structural components according to  claim 3 , characterized by being externally coated with a plate having a thickness of at least 2 mm and having been annealed at 500 to 700° C. and prepared from water glass and fillers selected from the group consisting of Al 2 0 3 , SiO 2  and/or carbon.  
   
   
       5 . A method for preparing the structural components according to  claim 1 , characterized in that the components are mixed, introduced into a mold and cured at 100 to 150° C., followed by bonding the annealed plates with the structural component using water glass.  
   
   
       6 . A method for preparing the structural components according to any of  claim 1 , characterized by having the shape of round or polygonal tubes.
