Alkali-Aggregate Reaction in Concrete
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 va...

The Alkali-Silica Reaction in Concrete
This book reviews the fundamental causes and spectrum effects of ASR. It considers he advances that have been made in our understanding of this problem throughout the world.
Alkali-aggregate Reaction in Concrete Roads and Bridges
This book provides a sound understanding of the alkali-aggregate reaction and how it affects the design, construction and maintenance of concrete roads and bridges. It draws on examples from the UK and around the world to relate experience of damage caused by this reaction and how the problems have been investigated and treated.
RILEM Recommendations for the Prevention of Damage by Alkali-Aggregate Reactions in New Concrete Structures
This book contains the full set of RILEM Recommendations which have been produced to enable engineers, specifiers and testing houses to design and produce concrete which will not suffer damage arising from alkali reactions in the concrete. There are five recommended test methods for aggregates (designated AAR-1 to AAR-5), and an overall recommendation which describes how these should be used to enable a comprehensive aggregate assessment (AAR-0). Additionally, there are two Recommended International Specifications for concrete (AAR-7.1 & 7.2) and a Preliminary International Specification for dams and other hydro structures (AAR-7.3), which describe how the aggregate assessment can be combined with other measures in the design of the concrete to produce a concrete with a minimised risk of developing damage from alkali-aggregate reactions.
Alkali-silica Reaction in Concrete
Concrete can deteriorate as a result of an interaction between alkaline pore fluids (prinicipally originating from the Portland cements) and reactive minerals in certain types of aggregates. The mechanism of deterioration is known as alkali-aggregate reaction (AAR); it can occur in a number of forms, the most common being alkali-silica reaction (ASR). This Digest is in four parts. Part 1 gives the background to the detailed and simplified guidance contained in Parts 2 and 4. Part 2 gives detailed guidance for minimising the risk of damaging ASR in new construction. Part 3 gives worked examples. Part 4 gives simplified guidance for new construction using aggregates of normal reactivity. This Digest gives guidance for general concreting applications; guidance for concrete in highly specialised applications is outside its scope. For highway structures, in particular, information is available from the Highways Agency.
