ALKALI AGGREGATE REACTIVITY-A CASE STUDY

摘要

Alkali Aggregate reaction is the main cause of deterioration in major Dams of some of the Hydro Electric projects. In 1983 distress due to Alkali aggregate reactions, particularly Alkali Silika Reactors (ASR), was noticed in two Indian Dams, namely Hirakud (Orissa) and Rihand (UP.). Investigations reveal that India has numerous sources of potentially reactive aggregates, mostly ASR with a range of alkali contents.
