3rd International Conference on Calcined Clays, Delhi, India


1. 3rd International Conference on Calcined Clays

After two successful conferences held in Lausanne (2015) and Havana (2017), the 3rd International Conference on Calcined Clays for Sustainable Concrete will take place from 15 to 17 October 2019 in New Delhi, India. This conference aims to follow up on the scientific studies and experiences of the application of calcined clays in cement and concrete construction.

The conference will be held at the India Habitat Centre located at the heart of New Delhi. With a rich history going back many centuries, the city showcases an ancient culture in a rapidly modernizing country. Delhi is well connected internationally and domestically by the India Gandhi International Airport (DEL). The proximity to world-renowned tourist destinations such as Taj Mahal and the pink city of Jaipur gives you an added appeal to visit.










2. News from our team members


In May, our Cuban LC3-team inaugurated the LC3-pilot plant at Universidad Central “Marta Abreu” de Las Villas in Cuba. The plant will be used for research and training purposes. It can also be booked from private companies to conduct studies.





The “International Conference on the production and use of cement and concrete” took place in Villa Clara, Cuba. It was organised by the Cuban LC3-team under the guidance of Fernando Martirena. In addition to presentations and discussions, the participants had the opportunity to visit the LC3-pilot plant and several LC3-exposure sites.




Throughout the last months, our Indian partners have worked on LC3-applications. Numerous projects have been completed. One of them is a check dam that was built in Orchha in the state Madhya Pradesh.

Currently, the Indian LC3-teams work on realizing marine and high-altitude applications. 


The LC3-Project activities have expaneded to numerous regions. The network is now spread across the globe. To facilitate the knowledge transfer from the LC3-team to the industry, two LC3-Technical Resource Centres (TRCs) were established Cuba and India. Over the past 18 months, they have successfully worked with mutiple partners across the world.




3. Research highlights

Two former LC3-PhD-candidates successfully finished their PhDs in the last months. The LC3-Project is thankful for their invaluable contribution and wishes both all the best for the future.

In her thesis, Dr Wilasinee Hanpongpun investigated the use of Limestone Calcined Clay Cement for Thailand. 

Dr Julien Ston explored basic creep and autogenous shrinkage of LC3 in his thesis study. 





4. Practical insights about LC3

The kaolinite content in clay is crucial to ensure a good performance of LC3 concrete. A simple and robust method for the determination of the kaolinite content has been developed using an oven and a scale only. Three temperature steps at 200°C, 400°C and 600°C and three corresponding sample masses permit to determine the kaolinite content. The results of this test were compared with thermogravimetric analysis and an excellent correlation was obtained.

The critical parameters of the test such as the mass of the sample and fineness of the material were investigated to ensure the robustness of the protocol.


5. Information Days in Vietnam and South Africa

The next LC3-Information Days will take place in Hanoi, Vietnam on 31 October and Cape Town, SA on 19 November 2019.

The format of the LC3-Information Days allows you to receive an overview of the comprehensive advantages of this technology. Presentations will focus on the technical, financial and environmental advantages regarding this innovative cement. During the events LC3 will be presented and discussed with a wide audience from academia, industry and policy.





6. 6th LC3-Doctoral School in Lausanne

The application process for our 6th LC3-Doctoral School from 10 to 13 February 2020 is now open.

The Doctoral School will give you an overview of the most recent advances on hydration of cementitious materials and especially blended cements.

The program includes detailed presentations, discussions and experiments of the most relevant and promising techniques for the study of cementitious materials. During the practical sessions, scientists and researchers will receive insights about all relevant factors which need to be considered to carry out laboratory experiments.
