ABSTRACT Water pollution is a serious problem for the entire world. It threatens the health and well being of humans, plants, and animals. As the world became more industrial and smaller due to communications and trade, accidental and purposive hazardous dumping have contributed to the problem of sources of water pollution. All water pollution is dangerous to the health of living organisms, but springs and borehole pollution can be especially detrimental to the health of humans. Springs and ...
CHAPTER ONE: INTRODUCTION 1.1 Background Uganda has got many Small and Medium Sized Contractors (SMSC) engaged in the construction business. Some of these (SMSC) change business name and scope within a short time because of the competitiveness pressures within the construction industry. Little is achieved by these struggling SMSC due to the level of development of the local construction industry (LCI). Recent studies show that the Local Construction Industry is not very competitive, undeve...
ABSTRACT This study presents the derivation of polynomial functions for the prediction of critical axial forces in bridge trusses. Four different bridge trusses were considered in this study, three of which are statically determinate while one is statically indeterminate. These trusses at different height to span (aspect) ratios were tested for critical axial forces under the same conditions. The graphs of their critical axial forces against aspect ratios were plotted and this led to the find...
ABSTRACT This study investigated the structural characteristics of chikoko mud-cement concrete. The structural characteristics of chikoko mud-cement concrete investigated were compressive strength, flexural strength, shear strength and split tensile strength while the elastic properties investigated were static modulus of elasticity, poisson’s ratio and shear modulus. The water absorption of chikoko mud-cement concrete as a reflection of concrete durability was also investigated. Ninety (9...
ABSTRACT The proposed Access Roads which will connect the Airport Road to the main gate of the African University of Science and Technology, Abuja, Nigeria and the proposed Bridge Housing Estate when constructed will foster broader community goals by promoting business activities within and around the University environment. Topographic data were taken, traffic study and traffic volume forecast where carried out; minimum curve radii and curve lengths were calculated The traffic study for the...
Abstract Pond ash is an unwanted product from thermal power stations. Way of reducing the pollution of pond ash disposal determinations is recycled and reused in different engineering applications. The quality of pond ash can affect the quality and strength of engineering applications. This research paper using fiber reinforcement techniques to improve the geotechnical properties of pond ash. Polypropylene fiber is used to reinforce for stabilization of pond ash. In this research, some labora...
CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF THE STUDY A mobile phone jammer or signal blocker is an instrument used to prevent cellular phones from receiving signals from base stations. The process of blocking the receiver to receive a transmitted signal is called Jamming of the signal. The jammer effectively disallows cellular phone signal when activated. These devices can be used in practically any location, but are found primarily in places where a phone call would be particu...

ABSTRACT Analysis of investigation on the characteristics of cornstalk blended ash cement was carried out based on the interest of coming out with a good pozzolanic material with all required cement properties. Hence, the supposed competitive demand relationship between cement products in construction works has been majorly wined by cement and this makes people to depend mostly on it despite the increase in price and some with inadequate properties. In an attempt to reuse ...
ABSTRACT In the face of a possible scarcity of natural aggregates in the future in line with sustainable construction, this research investigates the feasibility of the use of recycled coarse aggregates as an alternative to natural coarse aggregates in structural concrete. The recycled coarse aggregate used in the research was processed from waste concrete. The percentage of recycled coarse aggregates by weight of all in aggregates in the test mixes were 0%, 5% 10% 20% and 30 % respectivel...
ABSTRACT The major objective of this research is to examine the variation patterns of road traffic accident in Ilorin-Omu- Aran Road, Kwara State. The study used secondary data of Accident records and vehicular situation were obtained from the Nigeria police force (NPF) and Federal Road Safety Commission (FRSC). Chapter one of the projects deals and focused majorly on the general introduction which consist of the definition and meaning of road accident the aim and objectives of why the road...
ABSTRACT This project is based on Investigation into the operation of different transport agency in Kwara Express, Young Legacy, Kasmag and Emirate service Questionnaires and oral interview method of data collections were adopted, in which about 100 questions are distributed and oral interviews carried out in the study area. The results was analysed and fuel price is the major factor that is influencing vehicle operation costs. While cost maintenance of the vehicle is also contributed emer...
CHAPTER ONE BACKGROUND TO THE STUDY 1.0 INTRODUCTION Right from when man stated to build, he has been compelled to use the locally available materials around him. Building has now become major construction material allover the world has necessitated a critical study of its constituent materials. More so, the present economic crunch calls for cost saving measures on the part of engineers/researchers involved in the management of the country’s project. Hence, the need for resea...
CHAPTER ONE 1.0 INTRODUCTION This project deals with the design and production of ceiling board using Plaster of Paris [POP] gypsum materials. Plaster of Paris [POP] is a white powdery mixture of gypsum. It has been named such because the first deposit of gypsum was found is Paris. This powder when mixed with water solidifies, but without losing its volume. During manufacturing process, the gypsum is heated and as such, it does not necessarily require any high hea...
ABSTRACT The project titled “The effect of admixtures on properties of concrete: case study of sugar, cow bone ash, groundnut shell ash, and lime stone powder” was carried out with the aim of knowing the effect the of the various types of admixtures used on the properties of concrete, in term of the workability of concrete, durability of concrete and the concrete strength. The material used are cow bone ash, groundnut shell ash, sugar and lime stone powder. The cow bon...
