Low-carbon cement project planned in India

The demand for Limestone Calcinated Clay Cement (LC3), a low-carbon cement jointly developed by Indian and Swiss researchers, is set to grow in India with the country embarking on a $1 tn infrastructure development plan. After having tested its efficacy in pilot programmes, the objective is to make LC3 a standard general-use material and a feasible and viable product for sustainable development in the global cement market. 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.
