Alkali Reactivity of Carbonate Rocks— Expansion and …

In concrete, the alkali carbonate produced in the dedolomitization reaction will react with hydrated cement products and the alkalies will be regenerated, permitting a continuing reaction with the dolomite. The rates of both expansion and dedolomitization are functions of the calcite-dolomite ratio and texture of the rock. Although single

Limitations of the hydrotalcite formation in Portland composite cement

In the alkaline environment of cement paste, dolomite can undergo a so-called "dedolomitization reaction" [14], [15], [16]. In this reaction, dolomite reacts with portlandite to form brucite and calcite. However, Zajac et al. have recently shown that the reaction of dolomite in Portland cement paste results in the formation of a similar ...
