Evaluation the pozzolanic reactivity of sonochemically fabricated nano natural pozzolan
Ultrasonics Sonochemistry, 2012 Natural pozzolans are appropriate supplementary cementitious materials in cement and concrete industry. A simple sonochemical method was developed to synthesize nanostructures of natural pozzolan. Chemical composition, crystallinity, morphology and reactivity of the natural pozzolan samples were compared before and after the sonochemical process, by ...
