Chennai:
Indian Institute of Technology Madras is working with two other IITs
to develop limestone-calcined clay cement which would reduce cement
related carbon emissions by up to 40 per cent.
The project is funded by Swiss Agency for Development and Cooperation
(SDC) which has granted over 4 million Swiss Francs for the
development and testing of limestone-calcined clay cement (LC3).
This new blend substitutes up to half of the usual portland cement
used to make concrete, with highly abundant clay and limestone,
promising to reduce cement-related CO2 emissions by up to 40 per cent.
Applied globally, it could help bring down future CO2 emissions by
several notches, which would have a major impact on global climate
change.
By utilising low quality raw materials and by reducing processing
energy, this cement will support the growth of the India. The initial
results in India demonstrate that this cement can be produced using
technology that is widely available in the country and that the cement
can be used by construction workers without any additional training
required to handle the material.
The project is led by the Ecole Polytechnique Federale de Lausanne
(EPFL) in Switzerland, which has partnered with three IITs along with
the Central University of Las Villas from Cuba.
In India, the research groups involved are from IIT Delhi (IITD), IIT
Bombay (IITB) and IIT Madras (IITM). The application of the
technology is led by Technology & Action for Rural Advancement (TARA).
Agreements for research collaboration have been concluded and the
research programmes have been kicked-off at the centres involved.
The overall lead for the Indian team is Dr Shashank Bishnoi of IITD.
The other researchers involved are Prof. Biswajit Bhattacharjee from
IITD, Dr. Prakash Nanthagopalan from IITB, Prof. Manu Santhanam, Prof.
Ravindra Gettu, Dr. Radhakrishna Pillai and Dr. Sivakumar Palaniappan
from IITM, and Dr. Arun Kumar, Dr. Soumen Maity and Palas Kr. Haldar
from TARA. IITD and TARA have already demonstrated the feasibility of
the cement with field applications and laboratory tests and now the
larger team is involved in Phase 1 of the project for scaling-up
research and application.
With global demand for cement to double by 2050, driven by growing
demand in emerging economies, such as India, China, and Brazil, there
is a pressing need for such new cements. The funding from the SDC will
enable EPFL and its partners to do the necessary research and testing
for the introduction and standardization of LC3, so that it makes it
to the market as quickly as possible.
