Influence of porosity and grain size of carbonate rocks in the reactivity of limeInfluence of porosity and grain size of carbonate rocks in the reactivity of lime Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-10-012003enThe influence of porosity and calcite crystal size on the reactivity of lime produced from limestones from Kefalonia (Lk) and Arta (La) areas, and marbles from Asfendou, Crete (Ma) and Naxos Island (Mn) was studied. Lime reactivity was studied in terms of specific surface area and slaking temperature. In all cases the specific surface area displays a maximum at low firing temperatures decreasing thereafter. In rocks with low porosity lime reactivity depends on calcite crystal size. Very small calcite crystal sizes comparable to that of lime crystals yield lime with low reactivity due to low porosity of the end products. The lime produced from raw materials with large crystal size has inferior reactivity due to kinetic constraints. In materials with small calcite crystal sizes comparable to that of lime crystals reactivity of lime is controlled by porosity of the starting materialshttp://creativecommons.org/licenses/by/4.0/ Seventh Biennial SGA Meeting, At AthensInfluence of porosity and grain size of carbonate rocks in the reactivity of lime.pdfChania [Greece]Library of TUC2015-10-01application/pdf129.6 kBfree Christidis Georgios Χρηστιδης Γεωργιος T.
