Dangote Cement and FLSmidth have agreed to end the maintenance contracts on two Nigerian cement plants. In November 2013, FLSmidth signed contracts with the Nigerian cement producer Dangote Cement for operation and maintenance of production lines at their Ibese and Obajana cement plants in Nigeria for five years.
It has been recognised that high quality lateritic soils which are abundant in Nigeria can be used as fill, sub-base, and base course materials in highway construction. In this article, we are going to show the recommended standards for highway materials based on Federal Ministry of Works Specifications for Roads and Bridges (1997).
In this study, coarse aggregates was fully replaced with PKS at varying water-cement ratios (w/c) for concrete mix ratios 1:1½:3 and 1:2:4. Unit weigth of the PKS, slump, compressive and

Cement is sourced locally from Lafarge cement plants across Nigeria. With a capacity of 10.5 million tons, Lafarge is able to supply consistently high quality cement for all grades of concrete. Lafarge Cement conforms to NIS 441-1:2003. AGGREGATES:
worked on gravel mining in Nigeria and examined the effects and characteristics of aggregates in concrete. Bamigboye, Ede, Umana, Odewumi, and Olowu (2016) discovered that gravel aggregates have not been adequately utilized as they should, partly because of the fear that gravel cannot with-

Aggregates. Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the

Aggregates make up or occupy 60% to 80% of concrete volume making its selection highly important [3]. Aggregate should consist of particles with adequate strength and resistance to exposure condition and should not contain materials that will cause deterioration of concrete.
Coarse aggregate: Aggregates predominately retained on the No. 4 (4.75 mm) sieve. For mass concrete, the maximum size can be as large as 150 mm. ii. Fine aggregate (sand): Aggregates passing No.4 (4.75 mm) sieve and predominately retained on the No. 200 (75 μm) sieve. In accordance with sources: i.
