KALMATRON® KF-G
Inventions of the 21st century
A hair thin crack in the concrete specimen.
The same area 7 days after KF-G treatment. 
Magnified at x60 to x600 area of re -
crystallization on the edges of the crack. 
The microcrack has been completely re - crystallized by KF-G.
KALMATRON® KF-G 

is a liquid spray on a concrete for rehabilitation of degraded rheology

    KF-G represents a new concept in concrete rehabilitation technology and became highly recognized by its 
    effective performance and simplicity of application. In most cases, after KF-G is applied to the damaged area 
    there is no need for it to be covered with any additional layer. Concrete surface looks the same, but strength,
    corrosion resistance and impermeability to the liquids responds to features of High Performance Concrete. 

   APPLICATION OF KF-G FOR CRACKS  < 2 mm wide
    It is a common knowledge that cracks less than 2 mm in width are not repairable at all. The total volume occupied by       micro-cracks is much larger than the total volume of repairable cracks. KF-G actually heals these micro-cracks and    
    increases compressive strength by 30% to 50% after 28 days. 

  APPLICATION OF KF-G FOR CRACKS  > 2 mm wide
   If it is required that the concrete be uniformly cured, must be relined in accordance with Application FOR CRACKS   
   OVER 2 mm wide < [click it to see the map of KF-G application]. Superficial concrete densification results in radiation attenuation, which become in wide use for restoration of aged nuclear facilities.

  APPLICATION OF KF-G AS A REBAR CORROSION INHIBITOR 
As a Corrosion Inhibitor meeting the requirements of ASTM C1582, which is sprayed onto the concrete.   It chemically inhibits the corrosive action of chlorides on reinforcing steel and prestressed strands in concrete.
The self-healing process is visual just after KF-G spray.
The crack is completely healed. Seen is superficial slight white trace. After 4 days that white trace disappeared.    
Deformational crack with width at 3 mm.

INJECTIONS OR SPRAY? 
IT IS NOT A QUESTION,




NOT ANYMORE
Re-calcination of concrete by KF-G results in“sewing” of any voids including of microcracks with density increasing, measurable in at 4 to 72 hours depending on initial density loss.
KALMATRON® KF-G
   Pour or spray KALMATRON® KF-G as a water solution 
   and distribute it evenly by the brash as shown at right.        
   Treated concrete become waterproofed and strengthened 
   by resistance to compression, abrasion and rupture.  

   For the most of projects it is enough to accept project as   
   accomplished especially when resurfacing is not needed. 
Above are close ups of the crack on a concrete floor treated by KALMATRON® KF-G (at left) and result of re- crystallization after
30 hours shown at right.
