Alkali-Silica and Alkali-Carbonate Reactivity of Some Aggregates from South Dakota, Kansas, and Missouri

摘要

The report summarizes two investigations concerning alkali-carbonate reactivity in aggregates. Part one describes an instance of the identification of brucite in dolomitic limestone affected by an alkali-carbonate reaction. Part 2 describes concrete from structures, in some of which an alkali-carbonate reaction has taken place with a limestone containing no detectable dolomite.
