India: Ambuja Cement, a subsidiary of LafargeHolcim, supplied over 0.3Mt of cement for the Chenani-Nashri tunnel project that was opened in early April 2017. The company’s technical services teams provided technical support for the project by conducting cement mix design trials to achieve optimised mix proportion. It also held self-compacting concrete workshops to aid engineers and to provide support at the construction site to identify, diagnose and resolve problems. The group started providing materials to the project in 2010.
The new 9km single tube bi-directional Chenani-Nashri tunnel with a parallel intermediate lane escape tunnel of 29 cross passages, is considered one of the most challenging infrastructure projects in India in recent years. It is intended to make road travel safer and reduce traffic disturbances caused by unpredictable landslides, sharp bends, vehicle breakdowns and accidents on the existing mountainous route.
