Liberia: The International Finance Corporation (IFC) has announced a US$21.1m financing package for Fouta Cement, Liberia's second-largest cement supplier. The IFC said the move is to help increase local manufacturing and infrastructure development in Liberia and reduce the country's reliance on imported construction materials.
The financing package will help Fouta Cement to build and operate a 0.35Mt/yr clinker grinding plant in Monrovia, the Liberian capital. The financing package consists of a loan of up to US$5.4m from IFC's own account, a US$10.8m loan from the International Development Association's Private Sector Window Blended Finance Facility (IDA PSW BFF), and a loan of up to US$5m to be mobilised from Bank of Africa United Kingdom.

Australia: First Graphene has started a five year collaboration research and development agreement with construction chemicals manufacturer Fosroc International to develop its PureGraph graphene-based cement additive product range. First Graphene will provide access to its formulation and dispersion process technologies and Fosroc will take responsibility for additive raw material supplies and formulations, mixing and dispersion and extensive laboratory trials. The objective of the deal is to jointly develop a range of PureGraph-enhanced cement additives that Fosroc will add to its portfolio of specialty products.

Michael Bell, the managing director and chief executive officer of First Graphene, said, “The agreement with Fosroc is a significant further step for First Graphene as we implement our go-to-market plan to become the world’s leading supplier of graphene-enhanced cement and concrete solutions. Fosroc has significant penetration into multiple global markets that will be highly beneficial in helping expand our reach and educating the market on the significant benefits, including emission reductions, that graphene-enhanced products provide.”

First Graphene says that the clinker factor of cement can be reduced by up to 20% through the use of its PureGraph additive products during the final grinding phase of cement production.

Spain: Cementos Cosmos plans to scale down the production of clinker at its Córdoba cement plant as a result as the high cost of electricity. The Cordoba Day newspaper has reported that parent company Votorantim Cimentos said that clinker grinding operations at the site will continue to ensure a sufficient cement supply in the region.

Pakistan: Askari Cement has awarded a contract to Germany-based Gebr. Pfeiffer for the supply of three of its MVR vertical roller mills to replace the existing mills at its Nizampur cement plant. Two of the mills will be MVR 5000 C-4 cement mills with the capacity to grind 360t/hr of clinker to a fineness of 3250 blaine. The other mill, an MVR 5000 R-4 raw meal mill, will grind 520t/hr of clinker to a fineness of 12% R90µm. The Chinese contractor Hefei Cement Research & Design Institute will install an SLS V high-efficiency classifier on each of the mills. The upgraded plant is scheduled for commissioning in mid-late 2022.

Panama: Panamanian cement producers reused cooling water used in cement grinding at a rate of 88 – 100% nationally in 2020. The development is part of a concerted water conservation effort first launched by Argos Panamá.
