Pozzolanic activity
Pozzolanic Reaction and Activity: Pozzolanic reaction in portland cement with pozzolans Conversion of silicarich precursor to calcium silicate with good cementing properties Presence of aluminate in pozzolans forming calcium aluminate hydrates Parameters determining pozzolanic activity (grinding, crystallographic defects, chemical composition, reactive phases content, thermodynamic stability) Particle properties affecting pozzolanic activity (surface area, defects, reactivity of nonpozzolan materials, quartz activity, volcanic ash reactivity) Pozzolan Composition and Reactivity: Required composition of pozzolan (SiO + Al + Fe ≥ 70 wt.%) Correlation between pozzolanic activity and active phases in multiphase materials Importance of reactive phases content in determining overall reactivity Influence of thermodynamic driving force on potential reactivity Higher pozzolanic activities of glasses compared to crystalline compounds Factors Affecting Pozzolanic Reaction: Impact of mix proportions, water amount, and space availability Influence of replacement ratio of pozzolan for Portland cement Effects of curing conditions, temperature, and water to binder ratio Significance of blended cement mix design properties on pozzolanic reactivity Case Studies and Research: Roman Port of Cosa features hydraulic concrete and Pozzolana mortar Study on Pozzolanic Reactions of Natural Zeolites by Mertens et al.
