Abstract

Concrete is the most-used construction material in the world. Its production in huge quantities poses significant environmental challenges in terms of greenhouse gas emissions and natural resource consumption. One potential way of addressing these issues is recycling construction and demolition waste (CDW) to produce recycled aggregates (RA) which can be used to produce recycled aggregate concrte (RAC), a more sustainable alternatve to natural aggregate concrete (NAC). Experimental research on RAC has been performed for many years, spanning from the material to the structural level: short-term mechanical properties, durability, long-term properties as well as short- and long-term structural behavior. However, only recently have design codes begun to incorporate guidelines and equations for RAC. In this lecture, we will see the main experimental research on structural behavior of RAC as well as the efforts being performed to incorporate RAC design guidelines into new codes such as the new version of Eurocode 2 and the fib Model Code 2020.

Biography

Dr. Nikola Tošić is an Assistant professor of Concrete structures at the University of Belgrade’s Faculty of Civil Engineering and a Fulbright Visiting Scholar at the University of Notre Dame, IN. During his 7-year research career he has published 10 research papers in journals indexed on the SCIe list, 19 conference proceedings and one book chapter on the topics of sustainable concrete and concrete structures with recycled and waste materials, serviceability desing, Life Cycle Assessment and multi-criteria decision making. Nikola is an active member of the International Federation fo Structural Concrete (fib) where he is a member of Task Group 2.1 Serviceability models and Secretary of the Young Members Group. He has supervised over 20 BSc and MSc theses and worked on several projects with industry. He has also a Marie Sklodowska Curie Individual Fellowship grantee.
