Crushed rock, gravel, sand and clay are ubiquitous building materials widely used for rural and urban dwellings, and in the construction industry for civil engineering works such as roads, buildings, bridges and dams. The Basement Complex furnishes a rich source of crushed rock which is augmented with basalt, dolerite and limestone in some places. Laterite is a common building and road-surfacing material. River gravel of various sizes are widely available as aggregates and building material, especially in Akwa lbom and Cross River states.

Sand of glass-making quality has been found and assays in many parts of the country (Odukwe, 1981). In Port Harcourt, the Trans-Amadi sands contain over 99 per cent Silicon oxide (S,0g) and at Ughelli, another clean coastal plain, sand deposit assays 97 per cent Silicon oxide (S,0j. Both sands are used for the manufacture of bottles and window glass. The West African Glass Company at Aba utilises a local sand deposit. Many other glass sand deposits are known especially along the coast. Reserves are inexhaustible since full industrial use has hardly begun.

Clays of various kinds and grades abound throughout Nigeria's sedimentary basins and on the basement. Nigeria has a rich traditional pottery industry that dates from the Stone Age. In all parts of the country, native pottery is a vibrant traditional art form and an established cottage industry for earthenwares. Modern industrial uses of clay for ceramics and bricks obtain throughout the country. Ceramic works at Abeokuta (Ogun State), Ikorodu (Lagos State), Okigwe (Imo State), Umuahia (Abia State) and Suleja in Niger State produce glazed wares from local kaolin. Refractory clays for refractory bricks have been proven at Onibode near Abeokuta where the refractoriness is very high at about 1,750°C.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,jaw crusher supplier?ore spiral classifier Welcome all of you to visit our official website.pulverizer machine?http://www.hxjqchina.com/n123.html

In Enugu, beneath the coal seams, are vast deposits of other fire clays, with reserves of about 130 million tonnes. Other major clay deposits occur in Akwa lbom (Etinan, ltu, Onna, Uyo); Anambra State at Ozubulu (3.5 million tonnes) and Ukpor (4.2 million tonnes); Edo/Delta States at lgoriakhi (over 14.0 million tonnes); Imo/Abia States (over 2.0 million tonnes) at lgbere and Ogbuebule; Kaduna State (over 5.3 million tonnes) at Miraba- Rido and Kaohia; Katsina State (3.4 million tonnes) at Kankara; Ogun State (over 2.0 million tonnes) at Oke-Eri and Illefun Hill; large deposits in Ondo State; over 18 million tonnes in Plateau State at Nafuta, Worrom, Major Porter and Sabon Gida; and, in Sokoto State 2.0 million tonnes of pisolitic clays occur at Girl, and clay bricks are made at Wurno (RMRDC, 1989). Bentonitic clays, which are used for drilling mud, were first produced in Bende in Abia State in 1961-62.

Recent investigations by the Nigerian Mining Corporation, aimed at locally sourcing the enormous amount of bentonite imported into the country by the petroleum industry, established the existence of bentonitic clay reserves of over 700 million tonnes in the country, with the largest single deposit atAfuze in Edo State holding 70-80 million tonnes. Limestone and gypsum, the principal raw materials for cement manufacture, are very essential for a rapidly growing nation like Nigeria.
