Studies on the evolution of alkali silicate in a simulated alkali-silica reaction system

In this study, the interaction between the reactive silica present in aggregates and the alkalis and hydroxyls present in the pore solution of cement paste is simulated in a chemical model system and investigated experimentally. Various properties of the solid and liquid phases are investigated. The results show that the nano and micro structure and properties of the formed alkali silicate change significantly during this process.
