Rebar KomAR™ 

Tests showed the following advantages:

1. Density of composite rebar “KomAR” exceeds all existing analogs of composite rebar in the domestic and foreign market. Our rebar of more than 4 times easier reinforcing steel at equal strength characteristics that considerably cut transportation costs on delivery, shipment, and also operating expenses on a building site.

 

2. The composite rebar of the “KomAR” brand isn’t exposed to corrosive attack in the majority of hostile environment, including in the alkaline medium of concrete. By results of the tests which are carried out to JSC “SRC “Stroitelstvo” named after Gvozdev, Moscow, the rebar of the “KomAR” showed decrease in strength characteristics after 1 month of endurance in the concentrated alkali at a temperature of 60C no more than 6% that corresponds to its durability in a product not less than 100 years.

 

3. The coefficient of thermal expansion of composite rebar (5-9·10-6/0C) is comparable to concrete (7-10·10-6/0C) that ensures them collaboration at action of negative and positive temperatures, unlike reinforcing steel (13-15·10-6/0C) which at temperature fluctuations are deformed more, thereby causing high internal tension in concrete that leads to its destruction.

 

4. Heat conductivity of a composite is more than 100 times lower, than at steel that excludes creation of "cold bridges" in the bearing building designs.

 

5. The offered rebar of the “KomAR” doesn't carry out electric current, magnetic and radio transparency that allows to apply it in such buildings and constructions as hospitals, the airports, radar stations, various military constructions.
