LC3 Day Kenya
2024-02-13 09:00 - 15:30 (Africa/Nairobi)
Countries in Sub-Saharan Africa are witnessing very high development rates. With growth in population and urbanization, the demand for construction materials such as cement and concrete is increasing. Limestone Calcined Clay Cement (LC3) is a breakthrough cement technology that can help address this challenge. By using locally available materials and thanks to a lower production cost, LC3 can make housing and infrastructure more affordable across the continent. LC3 also provides an opportunity to combat climate change, as it saves around 40% of CO2 compared to conventional cement.
The LC3 Day Kenya will provide a comprehensive overview of the benefits of the LC3 technology. Leading policy-makers and experts from the realms of academia and industry will present the latest developments of LC3 in use, including a focus on the technical, financial and environmental advantages of this innovative cement.

4th ICCCSC in Nanjing
2024-05-15 - 2024-05-18 | Holiday Inn Nanjing Qinhuai South, China, No. 21 Mozhou East Road, Jiangning District, Nanjing, 211111, China
Cement concrete is the largest amount of artificial cementious material worldwide, and its impact on the world economy is huge. The energy consumption involved in the production of cementitious materials is high, and CO2 emissions account for 8% of the total carbon emissions. Improving the sustainability of cement concrete has become a major issue to improve socially sustainable development. Internationally, improving the low-carbon and sustainable characteristics of cement concrete is the focus of industry attention in recent decades.
The use of calcined clay in concrete, which has developed rapidly in recent years, produces a low-carbon cement-based material. Compared with traditional Portland cement, its cement clinker content can be as low as only 50% due to the use of a large amount of calcined clay and limestone as the key components. Limestone calcined clay cement has outstanding mechanical and durability characteristics and is considered to be a global alternative to a wide range of traditional Portland low-carbon cement materials. Its application in Latin America, South Asia, and other places is gradually growing.
The conference has been held three times in Switzerland (Lausanne, 2015), Cuba (La Havana, 2017), and India (New Delhi, 2019) as an important forum for low-carbon sustainable cement concrete. The 4th ICCCSC will be held in Nanjing, China, to focus on low-carbon sustainable cement production, performance, environmental efficiency as well as other topics to be presented in seminars. It is expected to further promote the development of low-carbon cement and concrete materials in the world and, with the significant demand for low-carbon cement in the countries along the Belt and Road route, it will promote the establishment of a new normal of cooperation among relevant countries, and promote the large-scale application of low-carbon cement concrete and the sustainable development of human society.
Conference topics:

Influence of processing on reactivity of calcined clays
Influence of clay mineralogy on reactivity
LC2 SCM: hydration, durability, and performance
Portland-calcined clay-limestone systems: hydration, durability, and performance

ICCCSC 2026, Cape Town
2026-02-04 - 2026-02-06 | Breakwater Campus of the University of Cape Town, Breakwater Campus, Cape Town, South Africa
Improving the sustainability profile of cement and concrete has become a decisive focus for fostering socially responsible development. Consequently, reducing the carbon footprint of concrete has gained increasing and widespread attention in research, development and industry.

The use of calcined clay in concrete production continues to gain momentum internationally and is widely considered the most promising solution for reducing the clinker content in concrete, consequently minimizing its carbon emissions and promoting sustainable construction. The timely International Conference on Calcined Clay for Sustainable Concrete (ICCCSC) was held in Switzerland (2015), Cuba, (2017), India (2019) and China (2024), serving as a key platform for discussing developments and application of low-carbon, sustainable cement technologies.
The 5th ICCCSC will take place in Cape Town, South Africa, covering topics related to low-carbon cement production, performance evaluation, application opportunities, case studies, latest research and development in LC2 and LC3 technology, and environmental efficiency. The focus will be on sustainable concrete technology and application, addressing production and quality control, fresh and hardened concrete properties, service life modelling, current and future developments, practical applications, and more.

We hope to bring together researchers, practicing engineers, cement producers, infrastructure managers, concrete technologists, students, and the supporting industry from around the world to share knowledge and experience on current developments in sustainable cement and concrete technology, and to identify future trends, application potential and further research required to support sustainability in the construction industry of the future.
The venue will be the Breakwater Campus of the University of Cape Town situated in the heart of Africa’s most popular tourist destination, the Victoria and Alfred Waterfront in Cape Town. The city of Cape Town and its surroundings are widely considered among the most beautiful places on the planet and the organizers of ICCCSC are looking forward to welcoming their guests to a vibrant, colourful and cosmopolitan environment.
