Add to ORKGIn this study, the interaction between the reactive silica present in aggregates and the alkalis andhydroxyls present in the pore solution of cement paste is simulated in a chemical model system andinvestigated experimentally. Various properties of the solid and liquid phases are investigated. Theresults show that the nano and micro structure and properties of the formed alkali silicate changesignificantly during this process.In this study, the interaction between the reactive silica present in aggregates and the alkalis andhydroxyls present in the pore solution of cement paste is simulated in a chemical model system andinvestigated experimentally.
