Introduction, the external characteristics of the damage with those caused by other actions, such as e.g. frost attack or shrinkage. The wide variety of aggregate types used in concrete worldwide, the different reactivity and proportions of the reactive constituents in the aggregates involved and the wide range

Alkali-Aggregate Reaction, contained in the cement paste and certain reactive forms of (usually silica containing) minerals in the aggregates, see Figure 4. The alkalis in the pore solution are derived from the hydration of the cement but may be augmented by alkalis in some aggregates or alkaline salts from the environment [

Symptoms of an Expansive Reaction during Routine Inspection,cture (Figure 9). It is part of an inspection process where detailed inspection and in depth investigation are important actions. This chapter covers review of existing records, field equipment and materials, personnel and expertise and so on. Also some general field symptoms of AAR are given to rec

Severity Investigation,me, the next step is to investigate the severity of the situation, see Figure 23. One should keep in mind that it is possible that some evidence of AAR may be found in concrete where siliceous material forms part or all of the aggregates, whether or not the concrete has cracked or expanded as a cons
