"We are in touch with several agencies including the National Council for Building Material in India. They have all shown keen interest in the material," said Karen Scrivener, Full Professor, Construction Material Laboratory at Ecole Polytechique Federale De Lausanne (EPFL), a leading technology institute in Switzerland.
"We will be able to strengthen the relationship (with India)," said Scrivener during a recent presentation at EPFL.
The Limestone Calcinated Clay Cement (LC3) can help reduce CO2 emissions by about 30 per cent and is made using limestone and low-grade clays. It is also cost-effective and does not require intensive modifications to existing plants to adapt to production of the new type of cement, Scrivener said.
"We hear that concrete is responsible for 5-10 per cent of man-made CO2 emissions. But this is remarkably low considering that it makes up about 50 per cent of everything we produce. It is the only material which can satisfy the growing demand for construction," she said.

The government has said there is immediate potential for investments totalling USD 1 trillion to build infrastructure. It also has plans for 100 smart cities to give a fillip to urbanisation.
The research partners in the project funded by Swiss Agency for Development and Cooperation, include IIT Delhi, IIT Madras, IIT Bombay and Delhi-based Technology and Action for Rural Development.
Scrivener said the real challenge is, however, to keep the demand up, lower the environmental impact and enhance resource efficiency. It is here that the LC3 is a viable alternative.
The project has already made an evaluation of the market. The "market is ready to buy it," Scrivener added.
