The effect of iron content on edge cracking tendency in cold-rolled commercial aluminium alloy 8011 under a mixed coconut/diesel oil (factory formulated oil) lubrication condition and under neem seed oil as an alternative has been investigated. Three different aluminium alloy plates each containing 0.708%Fe, 0.909%Fe and 0.931%Fe were produced by c... Continue Reading
The study was carried out to determine the separation of tantalum (Ta), niobium (Nb) and other metal ions using aqueous biphase system (ABS). The metal ions were produced from alkali fusion and dissolution of local tantalite ores procured from Plateau, Nasarawa and Niger states. The tantalite ore samples were crushed, ground and ball-milled for six... Continue Reading
The study was conducted during the 1992/93 irrigation season at the Kadawa sector of the Kano River Project (KRP) , with the primary aim of evaluating the performance of a part of the distribution system (distributary canal and field channels), irrigation water distribution and allocation methods and the relative water supply (RWS) index, as they a...

Northern Nigeria has a wide range of rainfall conditions, varying from an average annual rainfall of 60 inches in the southern-most parts to 15 inches in the extreme north. In all cases precipitation occurs during only limited portions of the year and during the dry season, crop cultivation is virtually at a standstill. Owing to the ever-present pr... Continue Reading
Various methods were used to design asphaltic concrete, hot rolled and mastic asphalts. Asphaltic concrete and mastic asphalt were designed principally using the Marshall procedure, while hot rolled asphalt was designed according to BS 594 and a method proposed for gap-graded mixes. A typical surface dressing design was also carried out for a light... Continue Reading
Bituminous Stabilization of S1lty Sand is one method of improving the engineering properties of the Soil so that it can be used as fill. Sub-base and base materials for construction. In order to improve these properties, the following tests were carried out in the laboratory, liquid limit, moisture content, specific gravity, relationship between dr... Continue Reading
The toll booth on the Kaduna - Zaria highway has been modelled as a queue system by adapting the makino model. Data collected on several days at the site was used to calibrate the model. Field conditions wherein a police check-point is encountered just before the toll booth justified the idealization of the system as a twostage queue. Allowance for... Continue Reading
The project investigates the possibility of adopting a composite beam consisting of concrete and timber, and consequently comparing the structural performance and the economical implications of this beam to a normal reinforced concrete beam. The idea to do this is borne out of the need to discover alternative(s) to reinforced concrete beams which a... Continue Reading
This study was carried out to investigate and quantify the effect of irrigation on annual recharge at the Kano project area of Kano river Project. The soil moisture deficit model was used in estimating the recharge and its sensitivity to data and model parameters was investigated. The mean annual recharge for the whole area was estimated at 101.1 m... Continue Reading
In earthwork construction the parameter used to check the effectiveness of compaction is the Relative Compaction, a parameter which cannot be evaluated until field density tests and laboratory compaction tests on representative portions of the material have been performed. The Standard Method of arriving at this value of Relative Compaction is time... Continue Reading
This study explored the possibility of producing Iron Oxide based arc welding electrodes using mill scales from Dana rolling mill. The performance of the weld joints using the produced electrodes and a foreign electrode was also examined. It is estimated that 4000-5000 tons of mill scales are produced annually without any immediate industrial appli... Continue Reading
This study is concerned with identifying and determining individual owners or occupiers of the parcels of land to be inundated by the dam reservoir of Gada Benye Irrigation-cum-Water Supply Project in Kaduna State. The Research was concerned mainly with the: - 1. Demarcation of the highest flood level of the reservoir. 2. Recording information for ... Continue Reading
This thesis evaluates the construction of small earth dams using the labour-based/light equipment supported technique. Actual cases of dam construction at three different locations in Nigeria have been used as case studies. Data from these projects were used to simulate likely construction costs using the labourbased technique and the traditional e... Continue Reading
