dc.description.abstractPozzolanicity is a very interesting issue regarding building materials, as a way to enhance mortars and concrete durability. This property results from the reaction between calcium hydroxide and silica and alumina based materials. Different types of natural and artificial pozzolans show pozzolanic activities that differ depending on the materials characteristics. Therefore, the study of this property, namely its reactivity with calcium hydroxide, reveals itself to be important in the selection of the type and content of these materials. This paper presents the results of several pozzolanic reactivity methods, applied to different pozzolanic materials. The selected pozzolanic methods include Chapelle method, Fratinni method and Strength Activity Index. Those tests have been applied to evaluate the reactivity of various kinds of artificial pozzolans. The correlation between the test methods are presented and discussed.pt_BR
dc.description.sponsorshipThe authors wish to acknowledge the Fundação para a Ciência e Tecnologia (FCT) for the financial support under project METACAL (PTDC/ECM/100431/2008) and to the enterprises Fradical, Portucel and IMERYS for the supply of pozzolans used in this work. The authors wish also to aknowledge the institutions of LNEC – Laboratório Nacional de Engenharia Civil and FCT–UNL – Faculdade de Ciências e Tecnologia – Universidade Nova de Lisboa for the technical support and facilities admission in order to perform the tests.pt_BR
