Publication year 2013 Abstract Alkali-aggregate reaction in concrete is the name given to a group of reactions leading to expansion caused by a chemical reaction between the alkalis 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 . One characteristic consequence of AAR, in the presence of sufficient moisture, is variable expansions. The expansion may cause extensive cracking of the concrete, especially if it is not restrained, leading to various forms of structural damage and durability problems. Maintenance costs of the structure tend to increase and the service life can become reduced Subject Building Engineering & Civil EngineeringSR - Structural ReliabilityTS - Technical SciencesBuildings and InfrastructureMaterialsBuilt Environment To reference this document use: http://resolver.tudelft.nl/uuid:2236017b-83c5-4136-aa12-a832f33acb2f TNO identifier 473656 Publisher Springer Verlag, Berlin Heidelberg ISBN 9789400765665 Source Guide to diagnosis and Apprisal damage to concrete in structures, 13-18 Series RILEM State-of-the-art Reports Document type bookPart Files To receive the publication files, please send an e-mail request to TNO Library.
