The presentation was successful and was selected as the second best. Several questions from the audience followed and opened a rich discussion. The first question was in connection to chemical variation of OSA over time, and sensitivity / robust testing of concrete with OSA was suggested. The second question was more of comment concerning the reduction of ordinary portland cement by OSA. Partial replacement of ordinary portland cement by OSA prevents the occurrence of alkali-silica reaction, which is connected to alkalies in cement. The discussion which followed the presentation was valuable for ICONDE project, especially WP4.
Delegates Siiri and Iveta established valuable contacts with other research institutes and industry operating in the given field. Furthermore, connection with Ukrain researchers from Chornobyl and NTUB was established to search for Ukraine researchers who would potentially join the ICONDE project.
