The Alkali-Silica Reaction in Concrete: R N Swamy: We use cookies to give you the best possible experience. Alkali-silica reaction (ASR) is a common cause of premature concrete deterioration, resulting in expansion and cracking of concrete elements. ASR is a chemical reaction between alkali hydroxides in the pore solution of concrete and certain siliceous (silica-bearing) rocks and minerals present in some concrete aggregates.

    Information on the development of alkali-silica reaction (ASR) damage in the UK, the chemical process of ASR, and the diagnosis and assessment of expansion and cracking on concrete. Data derived from research presented at the 8th International alkali-aggregate reaction conference held in Kyoto in , and additional field experience of the.   Alkali-Silica Reaction in Concrete by D.

Bhupinder Singh, in Waste and Supplementary Cementitious Materials in Concrete, Alkali–silica reactivity. Alkali–silica reaction takes place between alkalis (Na 2 O and K 2 O) from cement or other sources and certain reactive silica minerals present in the coarse or fine aggregates.

The chemical reaction can result in abnormal expansion and. Alkali-silica reaction (ASR) is of more concern because aggregates containing reactive silica materials are more common. In ASR, aggregates containing certain forms of silica will react with alkali hydroxide in concrete to form a gel that swells as it adsorbs water from the surrounding cement paste or the environment.

32 Practices to Mitigate Alkali-Silica Reaction (ASR) Affected Pavements at Airports aggregate as a base course under Item P, but notes that â concrete that has deteriorated from alkali-silica reaction (ASR) may be used for recycling base course with appropriate analysisâ (FAA ).

There are a number of ASTM tests used to identify alkali-silica reactive aggregates, and the effects of different alkali-bearing cements and pozzolans in accommodating the ASR reaction.

Nevertheless, in many areas of the country, the “good” aggregates have been used up, and “poorer” aggregates, of necessity or for unknown reasons, are. The Alkali-Silica Reaction in Concrete by R N Swamy (Editor) ISBN ISBN Why is ISBN important.

It considers he advances that have been made in our understanding of this problem throughout the world. The Reference Center was developed to provide users with access to pertinent information related to alkali-silica reactivity (ASR).

The Reference Center has been organized for quick and easy access to various resources, and will be updated regularly to ensure that the most up-to-date information is available.

Some concrete pavements commonly used at airports are susceptible to the destructive effects of alkali-silica reaction (ASR). The presence of ASR on concrete pavements can have a devastating effect on pavement performance, not only in terms of reduced functionality, but also in terms of shortened service lives.

lkali silica reaction (ASR) is a con-crete durability problem whereby certain forms of silica in aggregates react in high alkaline pore solutions in con-crete to form a reaction product that expands in the presence of moisture and results in deleterious cracking of concrete.
