Nigeria: Lafarge Africa's Roadcem product has been approved by the Federal Ministry of Works and Housing. The product is a cement additive that is used for soil stabilisation in road construction projects. It was developed to improve the characteristics of soils before they are used for the base, sub-base or sub-grade construction in roads.
Osita Ezedozie, the Director of Highways (Materials, Geotechnics & Quality Control), of the Federal Ministry of Works and Housing, said “Following the improved performance observed from the tests, pilot study and evaluation of Roadcem over ordinary Portland cement in soil stabilisation, approval has been granted for the introduction and use of Roadcem for stabilisation of soil in highway pavement sub-base course construction. At 5% Roadcem content, the stabilised sharp sand complies with all the specification requirements for a sub-base course and also achieves higher stability at a lower cost than stabilisation with ordinary Portland cement.”
