For concrete structures in demanding conditions
Concrete structures are made of concrete and iron to stand for demanding conditions. Demanding conditions mean to be exposed to various temperatures, humidity and chemicals. The most dangerous enemies for concrete reinforcement are chlorides and rust produced by chlorides in concrete reinforcement. Directly, the corrosion causes the rapid deterioration of strength properties of steel, and indirectly, splitting and cracking in concrete caused by expansion.
In Finland, annually 150 bridges are repaired and in every target, chloride contaminated concrete is purged and in several cases already spoil-rusted reinforcements have to be repaired. Identical repairs are also made for docks and other undersea constructions which are in contact with or close the seawater and thereby exposed to the load caused by chlorides the seawater contains.
But now we have a solution for these problems: CUSTONE-method
