Information that is currently available on alkali-aggregate reactivity (AAR), including alkali-silica reactivity (ASR) and alkali-carbonate reactivity (ACR) is summarized in the report. Chapters are included that provide an overview of the nature of ASR and ACR reactions, means to avoid the deleterious effects of each reaction, methods of testing for potential expansion of aggregates and cement-aggregate combinations, measures to prevent deleterious reactions, and recommendations for evaluation and repair of existing structures. Contents: 1.1 Scope 1.2 Alternative methods 1.3 Definitions 1.4 Notation 1.5 Fire resistance determinations
2.1 General 2.2 Concrete walls, floors and roofs 2.3 Concrete cover protection of steel reinforcement 2.4 Analytical methods for calculating structural fire resistance and cover protection of concrete flexural members 2.5 Reinforced concrete columns
