Surface deterioration of concrete occurs at the waterline of many hydraulic structures in contact with soft water in cold regions. Progressive disintegration of the surface leads to exposure of the coarse aggregate and ultimately of the reinforcing s

En betongkonstruktion som skadas av alkalikiselreaktioner spricker, förlorar sin hållfasthet, och blir utsatt för andra typer av nedbrytningsprocesser som frostangrepp och urlakning. Syftet med denna sammanställning är att vägleda och sprida ku

Spalling of concrete has been observed in water retaining concrete structures exposed to long periods of freezing weather. A hypothesis is that poor quality concrete, inadequate compaction or aging make hardened concrete susceptible to macroscopic ic

A measurement setup for in situ sampling of internal relative humidity and temperature in concrete structures was developed. The setup was used to evaluate the moisture conditions and to determine whether drying of the concrete components within a nu

The concrete structure of a reactor containment is pre-stressed with tendonsplaced in ducts. In some reactor containments, these ducts are injected withcement grout after pre-stressing. The cement grout protects the tendonsagainst corrosion and has t

This article presents a study on concrete alteration mechanisms due to 55 years of exposure to river water. Many hydro power structures in cold regions suffer from concrete deterioration at the waterline. Progressive disintegration of the concrete su

Superficial damage, similar in appearance to salt scaling of concrete, has been observed at the waterline of hydraulic structures, such as hydro power structures, bridge columns, canals and harbours. Progressive damage to the concrete surface results

The arch dam at Selsforsen and the buttress dam at Storfinnforsen are two concrete dams of which both have suffered from severe surface spalling on the upstream face, far below the full water supply level. A hypothesis is that macroscopic ice lens gr

The most severe types of destruction mechanisms are those causing internal cracking and thereby loss of cohesion of the concrete, i.e. internal expansive attacks. The internal frost damage belongs to this category of destructive mechanisms. The frost
