DESCRIPTION of KF-abg:

KF-abg is a radioactive shielding material for attenuation of radiation and liquid permeability.

KF-abg is an inorganic, cementitious gray powder without odor, with a dry bulk density of 2,000 Kg/m3. After mixing with water it becomes like a plastic dough with a wet density of 3,500 Kg/m3. The density after drying is about 2,000 Kg/m3. After 4 to 6 hours, it works also as a waterproofer. KF-abg provides radioactive protection immediately after application, and even in a powder condition.

¨       Any paint is applicable on the surface of a KF-abg layer.

¨       The durability of a KF-abg layer depends on the thickness of the layer and the outside conditions.

¨       The best conditions for KF-abg are wet surfaces and humid air.  The durability of KF-abg in dry and normal conditions is equal to the durability of highly dense concrete.

·       The shielding layer is easy to repair or replace in case of casual damages.  

·       We are able to produce various compositions of KF-abg, and use multiple application techniques for the different levels of radioactive protection.   

     USES of KF-abg:

KF-abg is applicable as a coating on any structure by plaster technology, or as an admixture into concrete mix, or by strewing directly on a source of radiation. Application is also possible by injecting into concrete, soil, masonry and reinforced concrete structures. The fields of application are diverse:  nuclear plants; storage sites of nuclear wastes; isolation of civil buildings, roads, tunnels, and bridges; deactivation of dusts, fly ash, etc.; and, injections into mines, sinkholes, tunnels, pipes, tubes, etc.

QUANTITY of KALMATRONÒ KF- abg: 

Before any operations, it is a necessity to determine the quantity of KF-abg per square unit, in accordance with the source of radiation and required level of protection. A determination of the required thickness of the layer needed on a job site is determined by a test application performed on a few areas with a minimum size of 30 cm x 30 cm, and a minimum KF- abg thickness of 5 mm. If attenuation is not sufficient, apply another 5 mm layer and continue this process until the radiation is stopped.   

PREPARATION OF KF-abg:

·       Use the required quantity of KF-abg per square unit of the concrete surface.

·       Add 1 part water, to 4 parts of KF-abg, based on volume, and mix for 1 minute.

PREPARATION OF SURFACE and CURING:

Wet surface with water until a soaked condition is achieved. For wooden, plastic or metal structures, apply flat wire net before application of KF-abg. After 6 hours, spray water on the KF-abg surface. 

QUALITY CONTROL:

·       Use the standard methods and equipment for evaluation of leaks, or remainder of radiation.

·       Repeat the Quality Control in accordance with local requirements. 

  BENEFITS:

·       KF-abg is the most workable and least expensive technology for protection of new structures, as well as for the restoration of resistance of building structures against radiation.

·       Deactivation of civil infrastructures by using plaster technology, with no additional staff training required.

·       Protective layer of KF-abg is applicable on wet,  
       contaminated and deteriorated surfaces.

·       Highest variability of the methods of application, and variable improvement of durability.

·       Can be applied in solid and powder form.
