Book excerpt: Alkali-aggregate reaction (AAR) in concrete is potentially a deleterious reaction which can lead to premature deterioration of major structures such as concrete bridges and roads. Severe cracking of the affected structure exposes the interior of the concrete to aggressive agents, leading to further deterioration. Once the structure is built with reactive ingredients, an ongoing expansive reaction takes place which causes continual cracking of the structure and widening of the existing cracks. The decision to repair such structures should be made carefully, based on the residual expansion of the concrete, the environment of the affected structure, the overall condition of the structure and its safety, and cost-effectiveness of the repair. These considerations should form a part of the management strategy of the bridge network. Measures to prevent AAR damage to concrete roads and bridge structure will also be outlined.

Available in PDF, EPUB and Kindle. Book excerpt: Alkali-Aggregate Reaction in Concrete: A World Review is unique in providing authoritative and up to date expert information on the causes and effects of Alkali-Aggregate Reaction (AAR) in concrete structures worldwide. In 1992 a first edition entitled The Alkali-Silica Reaction in Concrete, edited by Professor Narayan Swamy, was published in a first attempt to cover this concrete problem from a global perspective, but the coverage was incomplete. This completely new edition offers a fully updated and more universal coverage of the world situation concerning AAR and includes a wealth of new evidence and research information that has accumulated in the intervening years. Although there are various textbooks offering readers sections that deal with AAR deterioration and damage to concrete, no other single book brings together the views of recognised international experts in the field, and the wealth of scattered research information that is available. It provides a ‘state of the art’ review and deals authoritatively with the mechanisms of AAR, its diagnosis and how to treat concrete affected by AAR. It is illustrated by numerous actual examples from around the world, and comprises specialist contributions provided by senior engineers and scientists from many parts of the world. The book is divided into two distinct but complementary parts. The first five chapters deal with the most recent findings concerning the mechanisms involved in the reaction, methods concerning its diagnosis, testing and evaluation, together with an appraisal of current methods used in its avoidance and in the remediation of affected concrete structures. The second part is divided into eleven chapters covering each region of the world in turn. These chapters have been written by experts with specialist knowledge of AAR in the countries involved and include an authoritative appraisal of the problem and its solution as it affects concrete structures in the region. Such an authoritative compilation of information on AAR has not been attempted previously on this scale and this work is therefore an essential source for practising and research civil engineers, consultant engineers and materials scientists, as well as aggregate and cement producers, designers and concrete suppliers, especially regarding projects outside their own region.

Book excerpt: This handbook is designed to help highway engineers and bridge inspectors spot and fix this very damaging and difficult-to-detect problem, namely, alkali-silica reactivity (ASR). The 49-page handbook provides for the field identification of ASR in portland cement concrete structures, such as highway pavements and bridges. ASR occurs when silica or silicates in aggregates react with alkali in the cement to form a gel-like substance which absorbs water and eventually cracks the concrete. Some areas of the country are more susceptible to this than others. Accurate detection of ASR is the key to choosing the best rehabilitation strategy. The proper diagnosis and assessment of the problem is covered.

Book excerpt: Colorado frequently experiences pavement deterioration due to reactive aggregates. This study examined whether alkali-silica reactivity was also causing damage to bridge structures. A number of bridges were inspected and samples were extracted from five and subjected to a petrographer's analysis. Three of the five samples showed conclusive evidence of alkali-silica reactivity. Evidence was not conclusive in two other samples (A).
