Some Properties of Concrete Containing Aluminum Roofing Sheet Waste (ARSW) as Partial Replacement of Cement

Abstract This paper presents the results of investigation conducted to evaluate the properties of concrete containing aluminum Roofing Sheet Waste as partial replacement of cement by weight. The properties investigated included the setting times of cement-ARSW paste, workability, density, compressive strength using 168 numbers of 150 x 150 x 150 mm cube specimens. The chemical compositions and pozzolanic properties were also investigated. The results showed that: (I.) the chemical composition...

WEB BASED LOAN COLLATERAL-SECURITY MANAGEMENT SYSTEM FOR MICROFINANCE BANKS

ABSTRACT Microfinance Banks are developmental tool that focuses or centers on the extension of credit to the rural or low income earners. In recent time, most people with questionable characters had penetrated the Microfinance sector and deceive them by accessing credit facilities with false collaterals or items already used to access credits from other financial institutions. This has caused collision of various Microfinance Banks into a particula...

AN ASSESSMENT OF SECURITY ARRANGEMENT IN MURTALA MOHAMMED INTERNATIONAL AIRPORT, IKEJA-LAGOS

As an International airport as well as the gateway into our Country, it is expected to measure up to international standards in facilities, personnel, services, security, safety etc but unfortunately most of these areas are atimes neglected and consequently fall below acceptable international s...

An Appraisal of Concession of Onne Port to Intels Nigeria Services

ABSTRACT This work is to appraise the concessioning of Onne Port to Intel Nigeria Limited, the extent to which port reforms has positively influenced the development of Port Operations at Onne Port. To evaluate the developmental changes that have occurred, the researcher used statistical tools like spearman rank order and chi-square to analyze the data collected from the population of port users. Some hypotheses were developed. The study reveals ...

Effects of Gas Flaring on Cassava Crop at Aggah-Egbema in Ogba/Egbema/Ndoni Local Government Area of Rivers State

ABSTRACT The current research investigated the bioavailability of gas flare pollutant fallouts in crop tissues via the soil repository matrix around the Aggah-Egbema Oil Flow Station in Ogba/Egbema/Ndoni Local Government Area of Rivers State. Three sampling locations were established at 1, 2 and 10 km from the gas flare stack. Ambient air quality for SOx, NOx, COx, H2S, suspended particulate matter (SPM10), petroleum hydrocarbons, and trace metals (...

Assessment of Water Quality in Imo River at Oyigbo Local Government Area, Rivers State

ABSTRACT The water quality of the Imo River in Oyigbo local government area was ascertained using standard methods in this research. The important physicochemical characteristics of the river were investigated during the wet season of 2013 at six sampling locations. In situ measurements were made for water temperature, salinity, turbidity, dissolved oxygen (DO), biological oxygen demand (BOD), etc using the HORIBA U-10 water qualit...

Assessing the Performance of Anthocleista Dialonensis and Viscum Album a Eco-friendly Corrosion Inhibitors in Acidic and Saline Environment

ABSTRACT Leaf extract of Anthocleista djalonensis and Viscum album were investigate as inexpensive and environmentally friendly corrosion inhibitors for mild steel in 0.5 M H2SO4 and 3.5% NaCl was investigated by weight loss and potentiodynamic polarization techniques. The results revealed that Anthocleista djalonensis and Viscum album inhibited the corrosion reaction and the inhibition efficiency increased with increasing concentration of extract...

Variation in Groundwater Qaulity Parameters in the Vicinity of a Waste Dumpsite in Eneka, Rivers State, Nigeria

ABSTRACT The quality of groundwater impacted by a waste dumpsite in Eneka, Rivers State was studied using temporal approach. Groundwater samples were collected and analyzed for 27 parameters using standard methods. Water samples were collected with 250mL plastic containers from seven sampling boreholes. Samples for heavy metals were fixed with concentrated HNO3 in the ratio of 2:500. The descriptive statistics, one-way ANOVA, ...

PORT Concessioning and the Future of Nigeria Ports

ABSTRACT The inadequacies of Nigerian ports toward the delivery of quality services such as good infrastructure, cargo handling, vessel quick turn round time, corrupt and fraudulent tendencies has given rise to privatization and concession since this practices can brief about the required level of efficiency and effectiveness when compared with international standards. This research work would enable us ascertain the effects of concessioning of N...

Assessment of Trace Metal Contamination of Selected Fish Species From Choba and Aluu Axis of New-Calabar River, Rivers State, Nigeria

ABSTRACT This study investigated the trace metal contamination of two fish speciesClariasgariepinusandOreochromisniloticus obtained from the Choba axis (Downstream) and Aluu axis (Upstream) of New Calabar River in Rivers State. The fishes were dried, ashed and analysed for trace metals such as Zn, Pb, Cd and Cu using the atomic absorption spectrophotometer of model Unican Solar 969.The results obtained showed that Pb values ranged from 0.097 to 0.6...

Assessment of Borehole Water Quality, Potential Sources of Pollution and Prevalence of Water Related Diseases in Umuogonnama Community, Obio Akpor Local Government Area of Rivers State

ABSTRACT This study involved proximate analyses of four borehole water samples within an average distance of 30.25m from municipal solid waste dumpsites in Obio-Akpor Local Government Area of Rivers State, an area commonly known as Greater Port Harcourt or Port Harcourt Metropolis. Water quality and analyses of some bio-physico-chemical variables (pH, total suspended solids (TSS), total dissolved solids (TDS), colour, total coliform, faecal coliform...

Study of the Effectiveness of Materials Management in the Construction Industry in Imo State

ABSTRACT Materials Management in the Construction Industry in Imo State have been investigated. In order to reduce wastage of construction materials, the study focused on Success Level in Achieving Effective Materials Management as the Dependent Variable (Y) by introducing five Independent Variables (X1 to X5) thus (X1) Management of Materials; (X2) Skilled Professionals; (X3) Control of Materials; (X4) Inventory Build-up and (X5) Motivation of wor...

Effects of Devegetation on Agricultural Soil Quality at Nnewi North Local Government Area of South Eastern Nigeria

ABSTRACT This study evaluated the Impact of Devegetation on Soil environment of Nnewi North LGA in South East- Nigeria. It is caused by increasing demand for land with its consequences on disruption of soil ecology, climate change, breakdown of nutrient cycle and increase in soil erosion, siltation of dams and reservoirs, destruction of wildlife habitats, and loss of plant and genetic diversity. Soil samples for analysis were obtained in the study ...

Conversion of Agricultural Wastes into Poultry Feed for Sustainable Environment

ABSTRACT Agricultural waste has been of major source of environmental pollution and its utilization and conversion to renewable energy will discourage possible consequences associated with its discharge in the environment. This study was targeted at the conversion of waste to fish feed. Samples were collected in quantities from dumpsites abattoirs, market places using 20kg polypropylene bags and transported to the production sites. Pla...

Analysis of Factors That Constrain Work Schedule Performance in Construction Projects in Nigeria

ABSTRACT This study examines and analyses the salient factors that constrain work schedule performance and their contributions to the level of project time overrun in construction industries in Nigeria. The realization of project work schedule objectives is usually not achieved with certainly due to myriads of constraining factors encountered during the implementation stage of project life cycle. The survey method of research ...
