"A Study of the Hydration of Lime-Pozzolan Binders"

摘要: DTA/TG and TG/DTG thermal studies XRD investigations were carried out on pastes of lime-pozzolan binders to examine the relative hydration process. The prepared with two natural pozzolans hydrated lime, mixed together in different proportions. main phases formed are calcium silicate hydrate (CSH) mono-carboaluminate. growth CSH was greater for paste pozzolan richer reactive constituents. For a higher lime/pozzolan ratio, slowing formation observed, while monocarboaluminate more intense. hydroxide contents obtained by thermogravimetric analysis made it possible determine pozzolanic activities under examination. mortars various displayed characteristic hardening.
