Composition for construction of concrete floors, walls or roofs in buildings

Abstract

The present invention discloses the use of a composition including ballast, hydraulic binding agent and water for the construction of concrete floors, walls or roofs in buildings, in which the ballast in the concrete produced from the composition contains a sufficient amount of soap stone to achieve a concrete with higher specific heat capacity compared to common concrete.

1 . Method for using a composition comprising ballast, hydraulic binding agent and water for construction of concrete floors, walls or roofs in buildings, wherein the ballast in the concrete produced from the composition contains a sufficient amount of soap stone to achieve a concrete with higher specific heat capacity compared to common concrete. 
   
   
       2 . Method according to  claim 1 , in which the heat capacity for the concrete is higher than 0.95 kJ/kg·K. 
   
   
       3 . Method according to  claim 2 , in which the heat capacity for the concrete is higher than 1.00 kJ/kg·K. 
   
   
       4 . Method according to  claim 3 , in which the heat capacity for the concrete is higher than 1.05 kJ/kg·K. 
   
   
       5 . Method according to  claim 1 , in which the granule size for the ballast approximately is 0-32 mm. 
   
   
       6 . Method according to  claim 1 , in which the binding agent is Portland cement. 
   
   
       7 . Method according to  claim 1 , in which the concrete is concrete blocks for the construction of floors, walls or roofs. 
   
   
       8 . Method according to  claim 1 , in which the concrete is concrete slabs which are to be mounted on a surface.
