The Distribution, Structure, and Chemical Composition of Alkali-Silica Gels in Calcined Clay Concretes

The Distribution, Structure, and Chemical Composition of Alkali-Silica Gels in Calcined Clay Concretes

This study investigates the effect of calcined clays (metakaolin, metasilt, metaclay) on the chemical composition, distribution, and structure of alkali–silica reaction (ASR) gels. Using 10 wt% of calcined clays reduced concrete expansion and minimized cracking but did not inhibit ASR gel formation....
