LafargeHolcim has played a key role in the construction of India’s longest tunnel, which is located in the country’s northern state of Jammu and Kashmir. The new 9 km 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 was inaugurated by Indian Prime Minister Narendra Modi last weeks and reduces travel time between the two cities of Jammu and Srinagar by two hours, while also eliminating the dangers of the existing mountainous route.
LafargeHolcim’s Indian company, Ambuja Cement, developed tailor-made logistics to ensure the regular delivery of over 300 000 t of high quality cement to the remote area. The technical services team provided complete technical support, including conducting cement mix design trials to achieve optimized mix proportion. Following this, it was observed that Ambuja Cement retained its strength, despite the low temperatures in the region. The company held self-compacting concrete workshops for engineers to upgrade their knowledge and skills, and also provided continuous support at the construction site, to identify, diagnose and quickly resolve problems. The Group began providing materials to the project in 2010.
