India: Swiss, Indian and Cuban researchers have come together to develop limestone calcined clay cement (LC3), which can help reduce the carbon dioxide emissions of cement by almost 30%.
"The LC3 project is an example of scientific and technical collaboration between Switzerland and India. The innovative cement production process on which these institutions are working is of great economic and environmental significance," said Switzerland Ambassador to India Linus von Castelmur.
The LC3 is a synergetic hydration of clinker, calcined clay and crushed limestone to achieve the performance required from commercial cements, with clinker factors as low as 0.40. It also costs less than traditional types of cement.
"The testing and application phase is over, now it has to pass through standardisation committee before it is accepted by the industries. The research that has been done will not be patent protected but available to everyone," said Castelmur.
