Alkali-carbonate reaction of aggregatesthe essence of the reactionrequirementsmethodologyIn the construction industry carbonate aggregates are commonly used in processes such as concrete production. Aggregates which contain (in their mineral composition) dolomite and an admixture of clay minerals and ...
Alkali – carbonate reaction: significance of chemical and mineral admixtures Previous editions of Significance of Tests and Properties of Concrete and Concrete-Making Materials (ASTM STP 169, 1956) and its predecessors ASTM STP 22A, in 1943, and ASTM STP 22, in 1935, did not treat the subject...
Cause of alkali-silica reaction ASR is the most common form of alkali-aggregate reaction (AAR) in concrete; the other, much less common, form is alkali-carbonate reaction (ACR). ASR and ACR are therefore both subsets of AAR. ASR is caused by a reaction between the hydroxyl ions in the ...
Recent work shows that the rocks and minerals involved fall into three groups which leads logically to a three-fold subdivision of the reactions termed here: (I) the alkali-silica reaction, (II) the alkalicarbonate rock reaction, and (III) alkali-silicate reactions. A clearer understanding of ...
The formation of this carbonate can result in the reduction of concrete porosity and permeability. When all or most of the portlandite is consumed, further carbonation leads to a decrease of the pH of the pore solution, which creates an environment that facilitates corrosion of steel reinforcement...
