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...
Abstract Sustainable concrete provides a considerable solution to the increasing cost of conventional concrete production in the world. Though, it is generally described as cheap, however it’s design and cost implications for low income communities needs to be evaluated. Hence, this paper evaluates the production of sustainable concrete and its cost implication in Nigeria. Experimental design of high strength concrete made with steel fibre and bamboo fibre as reinforcement having a targete...
ABSTRACT This research is focused at designing of water storage facilities of size 875,000 litres (750,000 litres for underground water storage, and 125,000 Litres for elevated steel tank) of treated wastewater and its transmission system for the storage and re-use of treated wastewater. The project is aimed to structurally design water storage facilities and its transmission system from the reservoir to the overhead tank for the re-use of treated wastewater in Covenant University. The desig...
ABSTRACT The performance of a pavement depends on the quality of its base, sub-base layers and sub grade. As the foundation for the pavement's upper layers, the subgrade layer plays a key role in mitigating the detrimental effects of static and dynamic stresses generated by traffic. Therefore, building a stable base course is vital for constructing an effective and long lasting pavement system. This study proceeds from the basis that, construction of foundations of most engineering structure...
Abstract The conventional method of design of reinforced concrete structures commonly used in Nigeria is the BS 8110 method. This project shO\S a comparative stud~ of BS 8110 and Eurocode 2 for the design or reinforced concrete elements of a building Vith the aim of determining "hich of the two codes provides the most economic design is carried out using manual calculations. A library complex of three storey building was selected and designed taking into account dead and live loads and assumi...
