Publications

Articles published in journals and at international and national conferences, in Keynote Lecture Series, Seminars, Master’s Courses, Workshops, Roundtables, and other similar events, as well as doctoral theses, supervised, and co-supervised, dissertations, DEAs, and supervised final degree projects, which together support the manufacture of calcined clays in cement and/or ready-mix concrete Plants to design, dose, and manufacture new Portland cements with CC, with and without silica or limestone fillers, and other MCSs, which are more eco-efficient and environmentally friendly than current ones.

All articles and other publications and behavioural hypotheses derived from them, described below, have been the result of research carried out by Rafael Talero Morales throughout his working life and even subsequently.

Whether they were carried out exclusively or with the collaboration or invaluable support of some other researcher(s) and/or professor(s) and colleagues, to whom I am and will always be very grateful. Said research has been mainly focused on the durability of PC concretes –without and with natural and artificial, active and non-active mineral additions, above all and very especially (= MCSs)–, since they have been mostly responsible for the modification of its proven durability, but which are, nevertheless, so necessary to powerfully minimize the contribution of cement Plants to Global Warming or the Greenhouse Effect.

All of which has meant that its order of reference has necessarily had to begin with the subject of pozzolans, to continue with their influence on the hydration of the PC to which they are added. From the fresh state of their pastes (rheological behaviour), to the recently set and hardened (calorimetric behaviour) and fully hardened: Durability against attack, separately and exclusively, by sulphates and chlorides, and together in seawater, followed by their carbonation and AAR with the alkalis of the PC-MCS cement manufactured.

All the doctoral theses described at the end were directed or co-directed by Rafael Talero.
