This research presents the development of metal matrix composite using coconut shell ash as the reinforcement for automotive applications. Test samples were produced by stir casting method and machined into standard sizes for the purpose of determining micro structural analysis, physical, thermal, corrosion, mechanical and wear properties. The resu... Continue Reading
The characterization of Azara copper ore was carried out. The samples were collected from three different locations in Azara, Awe Local Government Area, Nasarawa State, Nigeria. The physical observation shows that the ore has metallic lustre, dark bronze with greenish stripe and irregular or uneven breakages. The results obtained from physical anal... Continue Reading
Traffic problems are increasing by the day. In Abuja, where the travel demand and the travel density are high, traffic creates numerous problems such as traffic congestion; traffic jam, and delays among others. ? Application of Global Positioning System (GPS) and Geographic Information Systems (GIS) in management of highway systems is now well esta... Continue Reading
Prediction of moment capacity of concrete slabs singly reinforced with carbon fiber reinforced plastics (CFRP) using simulated annealing is looked into. Equations for resistance moment are obtained based on the flexural requirements presented in ACI 440. 1R-06 (2006). These equations are then optimized using the Simulated Annealing (SA) algorithm. ... Continue Reading
This work is aimed at estimating the time available for compaction of a hot-mix asphalt mixture during construction.Laboratory tests were conducted on dense-graded asphalt and porous asphalt PA mixtures to evaluate their mechanical properties. Temperatures and mix characteristics tested in the laboratory were determined to be those typically found ... Continue Reading
The concern of humanity is the need to tackle the increasing challenges of severe land degradation and desertification of the ecosystem. The study examined the critical role of agroforestry practices in sustainable land management in rural areas of Kaduna State, Nigeria. Purposive sampling technique was employed in collecting data from three hundre... Continue Reading
Cities and towns all over the world are rapidly growing. Population increase and economic booming is one of the leading factors of urbanization in Nigeria. Zaria is among the major Nigerian cities which have been experiencing rapid structural and functional changes which need to be understood, studied and measured for development control and proper...

This research work reports the investigation carried out to determine the use of coconut shell as an aggregate in light weight concrete. Concrete samples were produced with different mix ratios, to determine the best and economic proportions that will give acceptable compressive strengths. Coconut shell aggregate exhibits low impact, crushing, and ... Continue Reading
In the quest for search of suitable coal deposits for power generation, the qualities of four Nigerian coal samples from Kurumu (Gombe State), Garin-maiganga (Bauchi State), Gindi-akwati (Plateau State) and Ogboyoba (Kogi State) deposits were analysed to assess their suitability for power generation. The coal samples were subjected to proximate ana... Continue Reading
A study of regeneration of naphtha reforming catalyst was carried out in this work. Two samples of deactivated catalysts were collected at different on-line reforming hours before their usual end of life cycle. The catalyst were characterized using X-ray diffraction (XRD), Xray fluorescence (XRF), Fourier transform infrared spectroscope (FTIR), sca... Continue Reading
This work presents reliability analysis of optimally designed reinforced concrete frames in accordance with Eurocode 2 (2004). A computer program in MATLAB (2004) was developed to analyze the frames based on direct stiffness method. The mathematical models of the design optimization problem were formulated and computer programs developed to obtain ... Continue Reading
The characterization of Gujeni iron ore was carried out in the course of this research work. The iron ore deposit is located in Gujeni village, Kagarko Local Government Area, Kaduna State. The Samples were taken from four different pits 1, 2, 3 and 4 at 100m apart and at 3m depth. The four samples were mixed together to form composite sample. The c... Continue Reading
