Suitability of Owoh Clay for the Production of Ceramics and Other Industrial Products

The suitability of Owoh clay for the production of ceramics and other industrial products hasbeen successfully carried out. The chemical analysis was carried out using X-ray fluorescence(XRD) technique. Particle size analysis was conducted using electric size shakers. Otherphysical properties tested were conducted using international accepted standard. The results ofthe chemical analysis conducted showed that the clay has Al2O3 (29.04%) and SiO2 (50.60%) asits predominant oxides with Cr2O3 (0...

The Impact of Highway Design and Construction Practice Defect on the Safety of Nigeria Roads

ABSTRACT Safety on Nigeria roads has become a thing of concern in recent times. This is as a result of numerous carnages that have characterized with Nigeria roads. This loss of lives and properties have been attributed to many factors including poor road design and defective construction practice. A road that is poorly designed, is in no doubt a threat to the safety of the road users. In this paper, therefore the way in which highway design and construction practice impacts on the safety of ...

ABSTRACT This project titled “the production of lead-acid battery” for the production of a 12v antimony battery for automobile application. The battery is used for storing electrical charges in the form of chemical energy releasing the energy as electrical energy when needed. It is a rechargeable battery that supplies electrical energy for Starting-Lighting-Ignition (SLT) system. The process involve in the procurement of the various parts viz electrodes, the lead grid panels, propylene co...

FABRICATION AND PERFORMANCE ASSESSMENT OF ECOFRIENDLY BRAKE PAD USING PALM KERNEL SHELL

The fabrication and performance assessment of eco-friendly brake pad using palm kernel shell (PKS) wasproduced for engineering applications. The materials were ground and prepared for the production of brake pads. Some physical and mechanical properties were used to determine the capability of the produced pads in service conditions. The production and testing of motor vehicle brake pads using locally available raw material has been undertaken and accomplished. The disc brake friction lining ...

CHARACTERIZATION STUDIES OF EZENIFITE CLAY FOR ENGINEERING AND INDUSTRIAL APPLICATION

The characterization of Ezinifite clay from Anambra State, Nigeria, is presented in this research paper. The clay sample was mined and then processed to a standard form for analysis using recognized processes. SEM, XRF, and DTA/TGA were used to determine the mineralogy, chemical compositions, and thermal behavior of the clay. The clay samples' morphological, chemical, and mechanical properties were studied at temperatures ranging from 900oC to 1200oC, with a temperature interval of 100oC. The...

Investigating the Degradation of Epoxy Resin Nanocomposite Exposed to Different Environments

Epoxy nanocomposites have found their path through a wide range of applications in marine, aerospace, automotive and electronics packaging industries. However, epoxy nanocomposites have proved to be vulnerable when exposed to different corrosive environments and the role of nanocarbon in leading the extent of changes of their properties have been a subject of research in several studies. This study aims at investigating the influence environmental degradation has on the mechanical properties ...

Development and Evaluation of the Optical Properties of Optical Glass Produced from Otamiri Silica Sand

ABSTRACT This work investigates the optical properties of glass prepared using Otamiri Silica sand mixed with analytical grade oxides as a function of their composition. Three batches were prepared with Phosphorus as the main variable of the SiO2-Na2OB2O3-CaO-ZnO glass system. The glass was melted in a ceramic crucible with a lid and the glasses melted after two hours of firing in a monolithic charcoal furnace. The effect of varying SiO2 and P2O5 on optical properties was determined using a ...

Mechanical and Microstructural Analysis of Equal Channel Angular Pressing of Almg3 Alloy with Additional 30o Twist Angle

ABSTRACT Equal channel angular pressing (ECAP) has over the years been used as a severe plastic deformation method to refine the grains and improve the strength of various metals. Even though this has been largely successful, research over the years has tried to increase the amount of strain induced in the materials used during this process so as to further increase the strength. In this research, an additional 30o twist angle was incorporated into the outlet channel of one of the ECAP dies ...

Synthesis and Characterization of Tin Iv Oxide (Sno2) Nanoparticles for Energy Applications

ABSTRACT Electrochemical capacitors (ECs) or Super capacitors (SCs) are energy saving devices which have excellent properties that include high power density, long cycle life, low temperature sensitivity and low maintenance cost. However, these devices have lower energy densities than conventional batteries. To improve on its energy density, SnO2 which is a metal oxide was considered as an electrode material because of its chemical inertness and thermal stability. SnO2 nanoparticles were syn...
