ABSTRACT Not only do soils serves as underfoot" for roads, airfields. train tracks, and houses that sustain our complex society: Engineers, typically geotechnical engineers, classify soils recording to their engineering properties as they relate to its use as foundation support building material. The study of geotechnical characterization of soils in Ikole-Ekiti, Ekiti State was carried out to determine the index properties and strength properties of the soil. The laboratory test carried ...
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 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 study was undertaken to measure the variational change in residual chlorine decay in water distribution network. A total of 330 water sample were collected at different periods of the day for ten days. Ten water sample locations at water stand taps, were taken for the study area in Calabar South Local Government Area of Cross River State, Nigeria. The effect of various Pipe diameter, water sample point distance, change in chlorine concentration with time on residual chlorine and...
ABSTRACT Environmental pollution with petroleum and petrochemical products has been recognized as one of the most important and serious challenges facing environment engineers. Disposal from mechanic sites, accidental leakages from petroleum carrying ships, vandalization of pipelines, have all contributed to the current common oil pollution in Nigeria today. The currently used physical and chemical remediation are effective for the degradation of petroleum products but the affected medium lo...
The present research discusses a problem of seal damages in dam gates due to influence of water flow through sluices passage way. The low level sluices (L.L.S) of Merowe dam were taken as a research field to investigate the influence of flow on the gate seal. The core of the problem is that the rubbery seal of L.L.S gates is damaged and washed out during yearly operation in flooding season. In previous years there is many solutions has been tried in two ways: first way is by improvement ...
