ABSTRACT Biogas generation is accomplished by anaerobic digestion of biodegradable material in a biogas digester. Anaerobic digestion as a process requires dynamic model for predicting process performance. Mathematical model for biogas production from anaerobic digesters described in this study was used to predict biogas generation using experimental data. Multiple regression analysis was used in analyzing two sets of data, the first sets of data contains four different experimental results ...
ABSTRACT This research work reports the investigation carried out to determine the strength and microstructure of lateritic concrete containing palm kernel shell (PKS) as partial . replacement of coarse aggregates. The study employed different mix proportions, which resulted in casting and testing 148 cubes at 7, 14, 21, 28, 60, and 90-days of curing, to determine the best and economic proportion that will give compressive strength. The materials and methodology phase of this research evalua...
ABSTRACT The development of soil and rock properties for geotechnical design purposes begins with developing/defining the geologic strata present at the site in question. Therefore, the focus of geotechnical design property assessment and final selection shall be on the individual geologic strata identified at the project site. This research work was been carried out to determine the shear strength characteristics of soils in Ikole Campus of Federal University Oye Ekiti, Ekiti State. Classif...
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...
Abstract Castor oil is classified as semi-drying oil because it oxidizes on exposure to air, giving a gummy film, and can be highly sulphated to make it emulsible in water. In the raw condition it is seldom used in fatliquoring of leathers because crude oil does not emulsify with water and hence the failure of the fatliquor process. Castor seeds were collected, sundried, and crushed. Castor oil was leached in a soxhlet apparatus using hexane as a solvent. An oil content of 28.4%was obtained....
ABSTRACT This research is concerned with analysis and design of the power transmission towers. Three types of the power transmission towers were considered in this research to investigate their structural behavior. Data have been collected about the types of towers, their usage, and the types of the applied loads. The study concentrated on the 220 kV double circuit’s Wawa- Wadi halfa Transmission Line Project, the three types of the transmission towers has different configurations and same...
Abstract This study was conducted to test the possibility of benefiting from the blast furnaces slag resulting from the production of steel at Giad Factory south of the city of Khartoum –Sudan. The study aimed to determine the effect of partially replacing some of the concrete mix components with steel slag to study the effect on the compressive strength and workability of the concrete mixture. A mix design was prepared for standard according to the British and US by using another mixes whe...
ABSTRACT This research project assesses the geotechnical characterization of soils used for the construction of the failed sections along Ikole- Oye Ekiti Road, Ekiti State, Nigeria. This road spans 23kms. The study area falls within coordinates 7. 7979306° N (Oye) - 7. 7982660 N (Ikole) and 5.3285505°E (Oye) - 5.5144930°E (Ikole). It is a known fact throughout the world that the conditions of any road largely depend upon its geotechnical properties such properties includes soil strength,...
ABSTRACT Water scarcity is a problem in many parts of the world. In some regions, there is physical water scarcity because there are not enough resources of water to meet the increasing demand, while other parts of the world have an economic scarcity, where resources are more abundant but poor governance and other problems render water unavailable for most of the population. Where the problem is economic water scarcity, there are many solutions that could ameliorate the problem, but most tim...
ABSTRACT Globally, natural disasters are becoming places lately, and they are the results of climate change due to natural forces. Some of these disasters like floods, earthquakes, landslides and draught happen, resulting in loss of human lives and properties. Flood occurs when two or more acres of dry land or two or more properties are inundated by water or mudflow. In this study, the reconnaissance survey of the study area was carried out. The topographical map of the area contributing run...
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...
