The influence of the anolyte solution type and concentration on lithium migration in mortar specimens

Electrochemical lithium migration has been suggested as repair technique for alkali-silica reaction affected concrete structure. In this method, an electric field is used to transport lithium into the material. Current studies have used anolyte solutions with various lithium salts at different concentrations. However, little has been said on...

A multiscale micromechanical approach to model the deteriorating impact of alkali-silica reaction on concrete

The alkali-silica reaction (ASR) in concrete is one of the most harmful deterioration processes, which leads to expansion and cracking of the material. To understand the evolution of ASR in concrete and its deteriorating impact on the material, a multiscale material model, from aggregate to concrete level, is proposed. The concrete, which at...

Influence of the alkali-silica reaction on the mechanical degradation of concrete

The alkali-silica reaction (ASR) is an important problem that has yet to be completely understood. Owing to the complexity of this<br/>phenomenon, a number of studies have been conducted to characterize its kinetics, its impact on the material, and its structural consequences.<br/>This paper focuses on the deteriorating impact of ASR on concrete...

Towards structural modelling of alkali-silica reaction in concrete

Structures affected by Alkali-Silica Reaction (ASR) include large massive concrete dams and bridges, which are considered essential for the infrastructure system, and not easily replaceable. The main feature of this reaction is the creation of a hydrophobic expansive gel which causes internal damage in the concrete. This damage is strongly...
