Uganda: Hima Cement, a subsidiary of LafargeHolcim, is a building materials partner for the on-going 600MW Karuma Hydropower project on the River Nile. The plant is being built by China’s SinoHydro Corporation at an estimated cost of around US$1.7bn. The project was started in 2013 and it is scheduled to be completed in December 2019.
Hima Cement has been one of two cement suppliers assisting it. It has provided a fine cement that maintains its early strength while requiring a lower water content. Over 114,000t of Powermax CEM II A-P 42.5N have been supplied to the project, chosen for its low heat requirements for hydration and its pozzolanic content which results in long-term durability. Delivery of this product has required a dedicated fleet of 60 bulk cement trucks when cement demand for the project was at its peak.

Cemex Colombia strikes deal to start Maceo cement plant 15 April 2019
Colombia: Cemex Colombia has reached a deal with the Attorney General allowing it to operate its Maceo cement plant in Antioquia. Under the terms of the government-brokered agreement Cemex will lease the land from CI Calizas y Minerales for around US$15,000/yr, according to the El Espectador newspaper. The lease has a duration of 21 years and this can be extended by another 10 years.
In 2016 Cemex fired several senior staff members in relation to the Maceo project and its subsidiary’s chief executive resigned. This followed an internal audit and investigation into payments worth around US$20.5m made to a non-governmental third party in connection with the acquisition of the land, mining rights and benefits of the tax free zone for the project. The US Department of Justice is also investigating the project.
