It is mainly used in road construction, earthwork and hydraulic engineering. A smaller part is returned to the metallurgical cycle, used as fertiliser or landfilled. With this use, iron oxides still contained in steelmaking slag are lost. In addition, the possibility of producing higher-grade products from steelmaking slag is foregone. In recent decades, many researchers have investigated the production of Portland cement clinker and crude iron from basic oxygen furnace slags (BOFS) via a reductive treatment. Carbothermal treatment of liquid BOFS causes a reduction of iron oxides to metallic iron, which separates from the mineral phase due to its higher density. Simultaneously, the chemical composition of the reduced slag is adapted to that of Portland cement clinker. In this study, German BOFS was reduced in a small-scale electric arc furnace using petrol coke as a reducing agent. The resulting low-iron mineral product has a similar chemical composition to Portland cement clinker and was rich in the tricalcium silicate solid solution alite (Ca3SiO5). Based on its chemical and mineralogical composition, similar to that of Portland cement clinker, the reduced BOFS has the potential to react comparably. In our study, the reduced BOFS produced less hydration heat than OPC, and its hydraulic reaction was delayed. However, adding gypsum has shown to accelerate the hydration rate of the reduced BOFS compared to that known from the calcium silicates of Portland cement clinker. Further research to improve the hydraulic properties of the reduced slag is essential. If successful, producing a hydraulic binder and crude iron from BOFS has economic and ecological benefits for both the cement and steel industries.

T1 - 7th international workshop on concrete spalling due to fire exposure - Proceedings N2 - The fire-induced spalling behaviour of concretes has a huge effect on the fire resistance of concrete components. Therefore, fire performance must be taken into account in the design and dimensioning of concrete structures. The use of new types of concrete and different types of cement or binder must also be considered. Despite decades of research, the mechanisms underlying the spalling phenomenon are not yet fully understood. However, knowledge about these mechanisms is the prerequisite for predicting the spalling behaviour as accurately as possible. Experimental research from material characterisation on the micro scale up to full-sized fire tests as well as the simulation and modelling of fire-induced damage processes offer the opportunity to investigate the spalling behaviour of concrete. Thereby, a variety of influencing parameters must be regarded. Against this background, the effect of avoidance strategies can be evaluated. Since 2009, the International Workshop on Concrete Spalling due to Fire Exposure (IWCS) offers a platform to get in touch with researchers and practitioners, exchange the latest research results and newly acquired data from real fire scenarios, and discuss current developments in the field of concrete spalling. After the successful workshops in Leipzig (Germany), Delft (Netherlands), Paris (France), Borås (Sweden) and Sheffield (United Kingdom), the 7th International Workshop IWCS took place in Berlin at BAM. It provided insights into the work of two RILEM Technical Committees. Based on this, various results of screening tests and large-scale tests for the assessment of the fire-induced spalling behaviour of concretes were presented, taking into account a large number of influencing parameters. Further topics of the workshop were the analysis of the mechanisms for the spalling phenomenon as well as the modelling and simulation of the spalling processes. A large part of the workshop was devoted to the high-temperature behaviour of various types of concrete. The workshop was dedicated to Prof. Diederichs, who passed away on 20 January 2022. With his death, the spalling community lost an internationally renowned expert in the field of fire behaviour of concrete and reinforced concrete components. He played a decisive role in the design of all previous RILEM TCs on the high temperature and fire behaviour of concretes and reinforced concrete components.

The conference provided a wide platform for the participants to communicate with each other and to share their research achievements. The distinguished keynote speakers, on the other hand, created a motivational academic atmosphere through the presentation of their outstanding research outputs. So, on behalf of the organizing committee, we are pleased to present this volume, containing selected contributions to this conference, of authors based in the industry, research institutes and universities. You will find that a variety of subjects around materials is being covered in these proceedings, including material's science, processing and properties, as well as measuring methods and applications. The selection of papers for this volume, we must recognize, was indeed a challenging endeavor for the about fifty specialized researchers that voluntarily took their time for the reviewing process for this IOP Conference proceedings volume. While we appreciate the efforts of all the author that submitted papers for this conference as well as the key role of the reviewers, we express our gratitude to all the members of the supporting staff, for their enduring effort to make the conference process a smooth one, and to the proceedings editing team, whose time and talent created the present volume from scratches.

The basis is education. ISEE stands for Innovation, Science, Engineering and education. This book summarises the presentations, discussions and Statements that were made during the ISEE-Africa conference held in Nairobi in 2019 from January 30 to February 1. The ISEE conference is a gathering of international researchers, scholars, and students, who came together to discuss jointly relevant topics related to better education for the engineers and architects of the future. Today, we know that the climate change is real. Many regions in the world are already suffering significantly, and the only way for humanity to overcome the challenges is to develop more sustainable technologies to the benefit of the entire global society. However, sustainable technologies require for deeper understanding, more conscious thinking, and smarter engineering. The only way how this can be achieved is to educate the developers, the decision makers, the engineers of tomorrow in a more knowledge driven way, and to equip them with the assertiveness required for the implementation. In this book, topics of construction and sustainable materials are linked to educational challenges. It addresses teachers, academic and political decision makers, and change drivers. The specific objective is to be critical, thought-provoking and inspiring. This way, we do hope that the book can deliver credible solution strategies for enhanced education for a new generation of decision makers with higher awareness of global and environmental challenges as well as innovation potentials.

Small 2.4 GHz modules can be either embedded or applied on the surface to determine the moisture distribution in material. Common modules, that are based on the highly available Bluetooth Low Energy standard, emit electromagnetic waves, whose signal strength gets dampened by water molecules. This effect serves as the basis on determining the moisture level in material. We will show how to apply this method in a meshed sensor network for online monitoring.

The rise of sub-Saharan Africa’s economies is significant to development. However, such development should be sustainable in order to increase the economic stability of Africa. In terms of sustainability, applicable concrete technology with relevance to the market needs is suitable to build up the infrastructure of a society. In the current sub-Saharan African market, there exists an enormous potential in sustainable research for innovative construction. Education is of key importance to innovation alongside a sound interaction with key players in the construction sector. The symposium includes keynote lectures from 10 international keynote speakers and technical papers from 25 young scientists, who were selected out of a high number of applicants based on the excellence of their scientific writing.
