Lithium-Based Chemical Admixture for Alkali-Silica Reactivity Concrete
Mapecrete ASR is a ready-to-use, liquid, chemical admixture that can be added to concrete mixtures for mitigating the probability of creating alkali-silica reactivity (ASR) in concrete. Alkali-silica reactivity is a chemical reaction that occurs between the reactive silica in aggregates used to make concrete and the alkalis (sodium or potassium) present in the concrete mix. The reaction causes the formation of a gel that absorbs water and swells, exerting stresses that can lead to cracking and premature deterioration of the concrete. The deterioration weakens the matrix, enabling the concrete to be further damaged by traffic loading, vibrations and environmental stresses such as freeze/thaw cycles or steel corrosion.
