Wolfram Schmidt obtained a Dipl.-Ing. degree from RWTH Aachen and a PhD from the Technical University of Eindhoven. He has been working at the Federal Institute for Materials Research and Testing since 2005, where he is responsible for the laboratory for concrete rheology and chemical concrete admixtures. 

He is the secretary of the German Rheological Society, a member of fib and RILEM officer. He is the initiator of various educational and scientific networking programmes, among others ISEE-Africa (Innovation Science, Engineering, Education), the ACCTA conference series (Advances in Cement and Concrete Technologies in Africa), and the pan-African interlaboratory proficiency testing scheme PACE-PTS. 

In 2018 he was awarded the German-African Innovation Incentive Award for research on the conversion of bio-based wastes to high-tech concrete constituents He is also involved in a variety of activities related to sustainable construction, one of which has been the GLOBE Global Consensus on Sustainability in the Built Environment.

Sustainable without borders - how Africa can escape established rules to make concrete solutions more local, climate-friendly, and sustainable than in the rest of the world.


Construction for urbanisation and infrastructure in sub-Saharan Africa (SSA) requires vast amounts of materials. Concrete remains the most viable solution, due to its scalability and low impact on carbon emissions and loss of biodiversity. For greener construction solutions, SSA has a better offset position than the rest of the world, due to the lack of historic technology boundaries and a marginal per capita carbon footprint. 

However, economic constraints, lacking regulations and informality are hindrance to the implementation of sustainable solutions. Therefore, Africa must catch up fast with global construction standards without perceiving them as limit. Beyond standards, locally developed, regionally sourced leapfrogging innovation is required for Africa to pioneer low carbon construction. 

The presentation highlights drawbacks of currently applied international regulations without relevance for Africa. Then, possible circular African solutions based on renewable resources are presented, which comprise organic and mineral concrete constituents and novel, digitalised approaches unique to Africa. 

Finally, their implementation is discussed in context of the high level of informality. The discussion shows that challenges exist but also underpin the tremendous potentials that lie within the continent to revolutionise construction technologies worldwide by thinking out of the established regulative box and customising solutions to the local framework.

3D Printing for Building Structures: Research and Development Advances in Nigeria


The construction industry in Nigeria plays a crucial role in the country's infrastructure development, catering to various sectors such as residential, commercial, and industrial. Nigeria's building construction background encompasses a diverse range of architectural styles, materials and construction techniques influenced by cultural, economic and environmental factors. Despite advancement in construction practices, Nigeria continues to face challenges with building collapses leading to loss of life, property damage and economic setbacks. Factors contributing to building collapses include inadequate structural design, poor construction quality, lack of enforcement of building codes and regulations and substandard materials. 

3D Printing technology has the potential to solve some of the key challenges in the building construction segment. This paper presents the progress that has been achieved in the development of the technology in Nigeria. The paper will discuss collaborative efforts between academia, industry and research institutions to develop 3D printing technology for Building structures in Nigeria. In particular the paper will highlight progress updates on potential research opportunities with Loughborough University (U.K), business partnership with Cipriani Nig Ltd, 3D printing machine manufacturing capabilities of 14 Trees Ltd (Kenya) and the design and construction supervision capabilities of Lafeza Consultants Ltd. 

The paper will present calculations and analysis of the stresses being experience by a typical 3D Printed wall to assess its structural integrity, safety and code compliance with Eurocode 6 (Design of Masonry Structures) and Eurocode 2 (Design of Concrete Structures). A proposed construction sequence for the technology will also be discussed to highlight a phased approach to assembly and integration of 3D printed components. The paper will be concluded by summarizing the progress achieved to date and the level of maturity that has been achieved for 3D Printing technology to be implemented in Nigeria Building Construction Industry.

From Tradition to Transformation: Local Innovations in Africa's Net Zero Infrastructure


Africa stands at the cusp of a monumental shift in its infrastructure development trajectory, spurred by the urgent imperatives of mitigating climate change, managing rapid urbanization, and fostering economic growth. Nigeria, as the continent's most populous nation, exemplifies this transformation vividly within its construction industry. Historically reliant on imported materials and technologies, Nigeria's construction sector has generated significant carbon emissions while offering limited local economic benefits. However, amidst the global pivot towards net-zero infrastructure, Nigeria finds itself at a crucial juncture, poised to pioneer innovative and sustainable solutions that prioritize indigenous resources, expertise, and economic advancement.


In the evolving landscape of Nigeria's infrastructure development, while there's notable progress, Nigerian innovators have yet to fully take the lead in driving sustainability. However, there's a growing wave of local entrepreneurs and visionaries who are beginning to pioneer innovative solutions for sustainable infrastructure. Concurrently, while the Nigerian government has taken some steps to support sustainable infrastructure, it needs to be deliberate and proactive in its actions. This entails implementing robust policies, incentives, and regulations that actively encourage and facilitate the adoption of sustainable practices throughout the construction sector. Against this backdrop, Nigeria finds itself at a pivotal moment, where concerted efforts from both the public and private sectors are vital to propel the transition towards net-zero infrastructure. By empowering local innovators and enacting supportive policies, Nigeria can unlock its potential to become a frontrunner in sustainable infrastructure development, thereby setting an example for the wider African continent. 


Drawing upon my extensive background as an engineering consultant and advisor in infrastructure development, I will shed light on the notable strides and positive outcomes resulting from the integration of local innovations in medium to large-scale infrastructure projects across Nigeria. Additionally, I will discuss the significant opportunities and challenges inherent in the gradual adoption and cultural assimilation of sustainable local innovations, which are pivotal in propelling Africa's journey towards achieving net-zero infrastructure development.
