ABSTRACT Domestic water supply is a daily necessity and key factor in human health and well-being. Without water, life cannot be sustained and lack of access to adequate water supplies leads to wide spread of diseases with children bearing the greatest health burden associated with poor water quality and sanitation. Drinking water is water that is of sufficiently high quality so that it can be consumed or used without risk of immediate or long term harm. Asin-Ekiti community is situated in I...
ABSTRACT Sand has traditionally been used as fine aggregate in structural concrete. It is usually imported from relatively distant places at high costs, and this increases the overall cost of making concrete and of providing housing in various Nigerian communities. This study investigates the performance of 409/o of laterite as fine aggregate in place of sand, and specifically seeks to determine whether lateritic concrete containing pies would satisfy the minimum compressive strength require...
ABSTRACT In an attempt to reduced non-renewable material usage, reduce green-house substances and at the same time be relevant to our environment, this research presents the progress of investigation going on to evaluate some properties of POEBA as partial replacement of cement in the production of structural concrete. This research work is carried out to determine the properties of Palm Oil Empty Bunch Ash (POEBA) when used as partial replacement for Ordinary Portland Cement (OPC) in concret...
ABSTRACT Rice Husk Ash (RHA) is one of the most active research areas that encompass a number of disciplines including civil engineering and construction materials. Grinded rice husk (GRH) and RHA is an agricultural waste product which is produced in large quantities globally every year. As the rice husk is piling up every day, there is a pressure on rice industries to find a solution for its disposal. Therefore as part ofa means to curbing this impending pollution problem. It is most essent...
ABSTRACT Agro-based and bio-wastcs generally referred to as solid wastes are good stabilization materials. Different solid wastes have been used by various researchers combining two or more at different times to treat soil and improve its engineering properties since the long term performance of any construction project depends on the soundness of the underlying soils. This paper has discussed the effect of the application of lime at varying percentages of 2%, 4%, 6% and 8%, oil palm frond a...

ABSTRACT The Reuse of waste glass in concrete production is among the attractive option of achieving waste reduction and preserving the natural resources from further depletion thereby protecting the environment and achieving sustainability. This present study examined the variation in the strength prope1ties of concrete using waste glass aggregate (WGA) as partial replacement for different coarse aggregates grading. 20mm and =(25mm coarse aggregates were partially replaced with WGA of respe...
ABSTRACT The condition and adequacy of the highway is often _judged by the smoothness or roughness of the pavement, deficient pavement conditions can result in increased user costs and travel delays, unnecessary braking and fuel consumption, vehicle repairs and probability of increased crashes. Pavement failure is usually a result of several factors which includes traffic impacts on the road, environmental factors, poor maintenance culture, geotechnical characteristics of the subgrade and ot...
ABSTRACT In an attempt to reduce non-renewable material usage, reduce green-house substances and at the same time be relevant to our environment, this research presents the progress of investigation going on to evaluate some properties of EPO-FBA as partial replacement of cement in the production of structural concrete. This research work is carried out to determine the properties of Empty Palm Oil Fruit Bunch Ash (EPO-FBA) when used as partial replacement for Ordinary Portland Cement (OPC) ...
ABSTRACT Concrete is a mixture of fine aggregate (sand), coarse aggregate (rock), cement, and water. The increasing demand of concrete for construction and development of infrastructure has drawn the attention of many researchers in searching for less expensive alternatives to the traditional materials employed in the construction industries in an attempt to reduce the high cost of construction. This paper features an experimental study on the replacement of sand with quarry dust and its inf...
Abstract In the period between 2016-2019 and the problem of searching for roads lies in the cost and time of projects in the construction experience in Sudan from exceeding the time specified in the contract between the owner and the executing party and exceeding the cost in contracts The research aims to know the cost and time control, monitor the project status and forecast the final work cost, to address weaknesses and defects in the plan and early identification of risks at the beginnin...
ABSTRACT The construction industry in Sudan is an important sector due to its enormous contribution to the country’s economic development. This in terms of employment opportunities and attraction of Foreign Direct Investments which grossly contributes to the country’s GDP. However due to the geographical, political, social and financial situation of the country, many construction projects are prone to delay, cost overrun or unsatisfactory quality, these three functions form the core of ...
ABSTRACT This study was carried out on River Atuwara in Ota, Ogun State, Nigeria with the aim of developing a coefficient of re-aeration model applicable to River Atuwara and other rivers in the Nigerian environment. This was achieved by sourcing for data once every month from 22 sampling locations of interest within a pre-selected segment of the river over a period covering the dry and wet seasons. The data collected include hydraulic data (depth, width, velocity and time of travel) and wat...
ABSTRACT Access to groundwater, a major source of direct drinking water in many developing countries, should not be assumed as access to safe drinking water. There is a need to prevent or minimize the contamination of groundwater, especially arising from solid waste disposal. This research work investigated the suitability of using clay and bentonite modified with sawdust as landfill liner materials for minimizing the migration of Pb2+, Cd2+ and Ni2+ in order to protect the environment and p...
Abstract Roughly 50% of the fruit mass remains as waste after fresh consumption or processing of citrus fruits. The build-up of these wastes typically signifies an economic and environmental nuisance owing to disposal problems. However, studies have shown that biogas can be recovered as a valuable product from citrus wastes due to its high concentration in soluble sugars, making it a suitable source of cellulosic biomass. DLimonene, the major constituent of essential oil present in citrus pe...
