2017-1-1 · Concrete with these two additives used in rational quantities is characterized by 58-59% increase of compressive strength and 83-91% increase of tensile strength in bending, with coefficient of crack resistance rising by 17-20%. The concrete abrasion corresponds to the G1grade of concrete and the concrete freeze resistance – to F 2600 grade.
Appropriate concrete cover should also be used. Reinforcing bars with improved corrosion resistance over traditional carbon steel reinforcing bars are readily available. When selecting a particular type of corrosion resistant bar, issues such as level of corrosion resistance, cost, and availability should be considered.

2015-12-28 · The 1993 AASHTO pavement design guide indicates that dowel bars "should be resistant to corrosion when used in those geographic locations where corrosive elements are a problem." [6] However, determining a dowel bar''s corrosion resistance is difficult because corrosion generally occurs slowly over the life of a concrete structure.
