ABSTRACT Waterborne diseases are linked to significant disease burden worldwide. Waterborne diarrhoea disease, for example, is responsible for tw o million deaths each year, with the majority occurring in children under five. Proper household water and sanitation can, however, increase resilience to waterborne disease risks. In view of the foregoing, this work has established a relationship f...
Building cracks are most common type of problem in any type of building. So, it is important to understand the cause and the measures to be taken for prevention. Though cracks in concrete cannot be prevented entirely but they can be controlled by using adequate material and technique of construction and considering design criteria. Due to some faulty steps during construction or some unavoidable reasons different type of cracks starts to appear on various structural and non-structural parts o...

Soils for engineering use are often classified based on properties relative to foundation support or as they might perform under pavements and in earthworks. Geotechnical classification systems today are designed to make it easy to equate field observations to estimates of engineering properties. As moisture content of a clay-like soil increases, it goes through four distinct states of consistency: solid, semi-solid, plastic, and liquid. Each stage is defined by significant changes in strengt...
ABSTRACT Bamboo is one of the oldest traditional materials used by mankind. They are the largest members of the grass family and are the fastest growing in the world. Bamboo is a substitute building material which is renewable, environment friendly and widely available as the wood resources are diminishing and restrictions are imposed on the felling of the natural forest trees. Due to its rapid growth and high yield, adaptability to most climatic conditions and due to its properties, bamboo...
ABSTRACT Soil is the ultimate foundation material which supports the structure. The proper functioning of the structure will, therefore, depend on the engineering properties of the underlying soil. The objectives of this research are to investigate the engineering properties of soils found in the site by conduction different types of laboratory tests. This research work is useful in providing necessary data or information that can be used in designing Civil Engineering structures in the site....
Abstract In countries where industrialization is on the rise there is a corresponding increase in waste production resulting from industries which eventually upsetsthe environment and community for which they provide. While most of these waste generated are hazardous and should be managed, others could be put to appropriate use either directly or after been recycled. Most agro-waste can be recycled and be used asraw materialsfor manufacturing various products. This research is designed to inv...
ABSTRACT Soils containing large quantities of clay and silt are the most burdensome to the engineer. These soils exhibit marked changes in volume with changes in water content and consequently affect the function of any layer lain upon it due to its shrink and up heave behavior when used as a subgrade or a layer built of it. The test assesses the geotechnical characteristics of silty clay soil in order to increase the shear strength and decrease the compressibility of the soil, so that the b...
Creating a friendly workplace which is devoid of pollution is a top priority globally. This study assesses the impact of noise from a polythene nylon production and recycling factory. The HD600 Datalogging Sound Level Meter was used for the assessment of noise within the factory and at twenty-three sampling points outside the factory. A World Health Organization standard questionnaire was also administered to selected respondents within and outside the factory to obtain information on su...
ABSTRACT This project presents the results of the investigation conducted on a lightweight foamed concrete using different reagents; Sodium Lauryl Sulphate (SLS) and Lithofoam, with a view to determining its potential as a construction material in Nigeria. The properties investigated on the foamed concrete having target density of 1800kg/m3 were: workability, bulk density and compressive strength. The foamed concretes produced using SLS were developed using a w/c ratio of 0.5 and a mix ratio ...
GENERATION OF ELECTRICITY USING A DOUBLE CHAMBER MICROBIAL FUEL CELL ABSTRACT The microbial fuel cells (MFCs) was used to generate electricity from waste water and fresh water, Design MFCs using different types of materials for the electrodes on the generation of electrical power from two MFCs, operated identically with a waste activated sludge feed and understand how bacteria and other living or...
ABSTRACT This project “maintenance of urban infrastructures (a case study of Ilorin metropolis)” lays emphasis on the various Infrastructures such as Roads, Rail, Electricity, Water-Supply, Solid Waste Management Facilities, Drainage Facilities and Sewerage. The various magnitude and the facilities provided were looked upon; the various defects and possible remedies to some specific infrastructures were also looked at. The major data collection procedures were from the various infrastruct...
ABSTRACT Urban population is rapidly increasing in Ilorin along with attendant increased water demand. The inadequacies of water supply services has forced the populace to depend on dug wells, boreholes, water tankers, street vendors etc. for their water needs. People spend hour’s daily carrying jerry can all around to collect and queue for water at the public water tap with high opportunity cost of time and intense economic wastage. This study assess the sustainability�...
ABSTRACT During this research work, namely; the undrained shear behavior of soils within Nnamdi Azikiwe University, five different samples within the university compound were analyzed. Some laboratory test was carried out for classification and identification of their engineering properties, these tests include particle size distribution, Atterberg limit test, specific gravity, and free swell tests. Also, shear strength test (UU triaxial test) at different cell pressures and one-dimensional c...
ABSTRACT This work is an attempt at recycling and re-use of waste paper within Mapoly Community. Since the day it is invented till today, paper is a part of human life in various ways and it is gaining even more popularity as years go by. As the consumption of paper has been exploited. Recycling of paper has become vital since the demand for paper has increased and natural resources are being exploited. In this study, the quantity of solid waste generated within MAPOLY were assessed. Also, co...
