Cementos Argos started the production and distribution of “Cemento Verde” which is a LC3-composition. Their product reduces up to 38% of CO2-emissions as compared to OPC.

The realisation of this project was conducted in collaboration with the LC3-project – Low Carbon Cement and Ecosur.

Congratulations to achieving this milestone!

We hope that you have already seen our announcements about the LC3-Information Day on 17 May 2018 in Zurich

This Information Day for Limestone Calcined Clay Cement (LC3) will be one of the project’s most important events of this year. The presentations will illustrate that LC3 does not only match OPC – CEM I performance with environmental benefits of 30% CO2 reductions, but it also offers significant financial advantages compared to OPC. In this regard, a key part of the event will be the first-time presentation of a techno-economic feasibility study for LC3. 

Please find attached the invitation card and program of the LC3-Information Day. For further information, visit our website www.LC3.ch 

The details of the event are as follows:

Time:                     Thursday, 17 May 2018
                                 09:30 AM to 4 PM              
Venue:                   EMPA-Akademie
                                 Überlandstrasse 129
                                 8600 Dübendorf, Switzerland

Registration:     Register through the online form here
                                 Or send a confirmation of your participation by e-Mail to LC3@epfl.ch 
We look forward to discuss with you about LC3 – the „cement of tomorrow“.
Please also note the possibility of a technical visit of a LC3-cement plant on 21 May 2018. Further information may be found here:  https://www.lc3.ch/21-may-2018-technical-visit-in-portugal/

Last week, the LC3-Project hosted its 4th DoctoralSchool. The researchers and scientists learned about hydration, pozzolanic reactivity assessment, XRD and microscopy, Mechanical behaviour, mix design and processing. 

In 2019, the 5th Doctoral School will take place. The details are as follows:

23rd to 26th April 2019


35 participants from 18 countries participated in the 4th LC3-Doctoral School in April 2018

03Apr 2018

Prof. Karen Scrivener opened the 4th LC3-Doctoral School from 03rd to 06th April at EPFL, Lausanne. We are happy to welcome 35 participants from 18 countries who will learn about the use of blended cements. The programme covers aspects of hydration of blended cements and the physicochemical characterisation of supplementary cementitious materials particularly calcined clays. The focus is on practical work with two afternoons devoted to laboratory practices on microscopy, XRD and calorimetry.

The LC3-project presented its technology and advances during the 5th Stakeholder Meeting at India Habitat Centre in New Delhi. The meeting was held on 06 February 2018 and included presentations from the project partners Swiss Agency for Cooperation and Development, EPFL, IIT Delhi, IIT Madras and TARA. In the following representatives from the industry provided insights on their production of LC3. Most importantly, enriching discussions were held in order to empower the technology, its production and application in the future. 

Prof. Dr. Karen Scrivener (Director of the LC3-project) presented LC3 to a wide audience during the 5th Stakeholder Meeting of the in New Delhi, India.

02Feb 2018

The LC3-project concerns Limestone Calcined Clay Cement which has a huge potential to lower CO2 emissions of cementitious materials. Significant progress has been made over the first three years of the project including extensive research, laboratory trials and first industrial productions. These results were shared on 02 February 2018 with an international audience at the 4th Stakeholder Meeting of the LC3-project. 

The meeting also included an introduction to the LC3 Technology Resource Centre (TRC) in India. The TRC has been initiated to provide state the art knowledge on LC3 and related products. The center provides consultancy services for establishing feasibility of LC3 in cement production and testing facilities for use of LC3 in concrete and concrete applications. The network offering support consists of IIT Delhi, IIT Madras, TARA, EPFL  and CIDEM Cuba. Direct contact to the TRC: lc3trc@devalt.org

LC3 project is pleased to announce a new collaboration between The Indian Institute of Technology Delhi and JK Lakshmi Cement Ltd..

This collaborative effort has made it possible the first full-scale trial production of a new cement known as Limestone Calcined Clay Cement (LC3) and at the same time developed a new environment friendly additive for concrete that makes it easier to produce high performance concrete at a lower cost.

Last year, JK Lakshmi became the first cement company in the world to carry out a full-scale plant trial production of the cement. The cement was produced at the Jhajjhar unit of the company. Trial applications of the cement have shown that it can reduce as much as 30% CO2 emissions and 20% energy consumption in cement production. Still, the performance of the concrete produced using this cement exceeds those using cements commercially available today in most aspects. The production is also one of the first such collaborations between the cement industry and academia to develop mainstream products. Full-scale trial applications of this cement have shown that it can be effortlessly introduced without any changes to the existing construction practices.Trials of the cement in the field and in ready-mix concrete plants have yielded excellent results.

Very importantly, the collaboration on LC3 led to the partners exploring several new fronts where technological developments could significantly impact sustainability, quality and costs. One such result is a new concrete additive that can be used to increase strength of concrete and to improve its durability. The additive reduces the requirement of energy-intensive and expensive cement in the concrete, thereby reducing construction cost and achieving as much as 20% increase in strength. It is foreseen that this product will find usage in high-performance applications like water-proofing, high strength concrete, self-compacting concrete, etc.
At the same time, it promises to reduce the cost of more common applications like masonry construction, wall plaster, road pavers, and walling blocks. The effort is in line with the Government initiative to provide housing to all by 2022 at a reasonable cost and environmental impact.

“The challenge of continuing to develop, without irreversibly harming the environment and affecting the future generations, can only be addressed through innovative thinking. I am confident that this collaboration will develop a synergy between the experience and knowledge of the industry and the ability of the young minds at our research institutes to innovate, to develop solutions that will allow India to continue developing without harming its future prospects.”

“Direct interaction with the industry will help us to utilise the great potential in our research institutes for the development of technologies that are relevant to our society. This will also ensure a more practical and hands-on training for the students and researchers, instead of rote learning”.
