**Preface to "10th MATBUD'2023 Scientific-Technical Conference"**

The 10th MATBUD'2023 Conference on 'Building Materials Engineering and Innovative Sustainable Materials' was jointly organized by the interdisciplinary research group of the Faculty of Civil Engineering and Faculty of Civil Engineering and Physics at Cracow University of Technology in Poland and the Nantes Université IUT Saint Nazaire GeM Institute in France.

The auspices of the Section of Building Materials Engineering, which is a part of the Committee of Civil Engineering of the Polish Academy of Sciences and the Construction Commission, Cracow Branch of the Polish Academy of Sciences, were extended to the organization of the conference.

The event took place within the framework of the Welcome to Poland project financed by the Polish National Agency for Academic Exchange (NAWA): "MATBUD'2023—Developing international scientific cooperation in the field of building materials engineering" BPI\_WTP\_2021\_1\_00002.

The scientific committee worked under the chairmanship of Prof. Lech Czarnecki (Honorary Chairman) and Prof. Izabela Hager (Chairwoman; the project coordinator).

We would like to express our gratitude to Prof. Lech Czarnecki, the Honorary Chairman of the Scientific Committee, who has played a key role in MATBUD events from the outset, generously sharing his time and expertise with us. Our heartfelt thanks go to him and all members of the Scientific Committee for their voluntary paper review and valuable suggestions during the preparation of this conference.

We would like to express our heartfelt appreciation to Professor Jacek Sliwi ´ ´ nski, the originator and architect of these cyclic meetings, who has devoted his time and effort to organizing MATBUD events with unwavering commitment since its first edition in 1996, and has also provided strong support for the organization of these 10 events.

This year, we received about 78 paper submissions, which were reviewed by national and international experts. In total, 44 of the received papers were accepted by the Scientific Committee for oral presentations at the conference and for publication in the Proceedings.

The primary focus of this conference was several areas of building materials engineering: development, processing, and the evaluation of properties and applications. MATBUD'2023 mainly emphasized cement and alkali-activated binders, aspects of durability, and innovative sustainable materials. Research in materials engineering is presently oriented towards finding waste management solutions for structural material production and developing cement composites regarding their manufacturing (e.g., 3D printing) and design (e.g., fiber-reinforced concretes).

The conference hosted participants from over 45 research units worldwide.

The organizing committee would like to express great gratitude to all the authors and participants for their valuable contribution to the conference.
