Project Development Philosophy

The markets to be served will be primarily in south-western Nigeria, with Lagos and Lagos State being the dominant markets. The cement produced will conform to the EN-197 specification and will be of the CEM II/B-L 32.5N grade for which the demand is highest in Nigeria.

This cement contains 20 to 35% limestone in addition to Portland cement. The E-Block cement factory will therefore need to manufacture 1.69 million tonnes of Portland cement clinker per year, at a rate of 5,200 tonnes per day, for the 325 days during which the equipment on the factory will be designed and installed to operate.

The location of the factory has been selected following raw material investigations on the proposed land in Eggua Igbogila and Araromi Ikomi Oba area. The area falls in the contact zone between the Ewekoro and Ilaro geological formations. The Ewekoro limestone zone extends from south of Shagamu in Ogun State to the Republic of Benin, with the representative outcrop being at Ewekoro. This Ewekoro limestone will be the major raw material for the manufacture of Portland cement clinker and cement at the factory. This limestone is overlain with clay deposits which will be used as the secondary raw material for clinker manufacture.

The limestone and clay will be mined by the open-cast method. The clay material will be extracted with hydraulic shovels, while the limestone will be drilled and blasted to break the material from the ground before loading and hauling to the raw material crushers at the factory.

In the plant the raw materials will be blended together in the correct proportions to meet the chemistry targets for the manufacture of Portland cement clinker. This blended mixture of raw materials will be dried and ground to a fine powder in a vertical roller mill. The resulting raw kiln feed will then be fired in a rotary kiln, converting it into the Portland cement clinker. The kiln will be fired with imported coal. The clinker will then be ground together with imported gypsum and limestone in vertical roller mills to produce the CEM II/B-L 32.5N grade cement. This cement will be packed in 50kg sacks and loaded onto customer's trucks for delivery to market.

The E-Block Cement Plant will deploy state-of-the-art equipment for cement manufacture with all necessary steps being taken at each manufacturing stage to minimise environmental impact. 748 people will be employed on the factory providing significant economic benefit to the local area, Ogun State and Nigeria.
