ABSTRACT This research presents Artificial Neural Network Model for the prediction of the Modulus of Elasticity of Concrete. Egbulonu (2011) equation derived from Scheffe’s (4, 2) simplex equation for predicting the Modulus of Elasticity (MOE) was used to generate 800 values. These data represent different values of Modulus of Elasticity (MOE) out of which, 571 values were selected randomly by the artificial neural network. From the selected values, 400 were used for training the network, ...
ABSTRACT Several approaches using regression functions have been proposed over the years for predicting either the desired compressive strength of concrete or the mixture proportions of its constituent materials. This study as part of the continuing effort, presents models developed using Ibearugbulam's regression principle for predicting the desired compressive strength of granosand concrete when the mix proportions are known or vice-versa. Laboratory experiments were carried out with ...
ABSTRACT Degree of compaction (R %) value is an indicator in strength of earthwork construction. In the design of irrigation earthwork construction, degree of compaction value of compaction characteristics is often used, but laboratory test is time consuming and laborious. Fine aggregate classification and compaction characteristics are routinely determined for in-situ and borrow area (reservation area) soils used in the irrigation earthwork constructions. Developing regression based model to...
ABSTRACT There has been a growing concern in the development of alternative building materials to ensure housing for low-income earners who cannot afford owning houses due to high cost of modern materials. Plantain (Musa paradisiaca) peels are the major byproduct of plantain fruits, constituting about 40% of the fruits but are presently underutilized. This work covers the investigation into the effect of Ripe Plantain peel ash (RPPA) and Unripe Plantain peel ash (UPPA) as admixtures to concr...
ABSTRACT A bridge is a structure built to span physical obstacles without closing the way underneath such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. There are many different designs that each serve a particular purpose and apply to different situations. Designs of bridges vary depending on the function of the bridge, the nature of the ten-ain where the bridge is constructed and anchored, the material used to make it, and the funds available t...
ABSTRACT The importance of concrete in modem society cannot be underestimated. There is no escaping from the impact of concrete on everyday life. Concrete is a composite material which is made of filler and a binder. Typical concrete is a mixture of fine aggregate (sand), coarse aggregate (rock), cement, and water. Nowadays the usage of concrete is increasing from time to time due to the rapid development of construction industry. The usage of concrete is not only in building construction bu...
ABSTRACT This study investigates the influence of two main geotechnical properties of soils in the town of Ikole-Ekiti on civil engineering construction. The strength and compaction characteristics of the natural soil were determined. The investigation was carried out through laboratory tests on disturbed and undisturbed soil samples obtained from four trial pits (Samples A, B, C & D) in the town, across Ilotin, Ijemo-Titun, Yeye-Oba and Asin respectively. The samples were collected between ...
ABSTRACT Disinfection of water is a crucial step in the treatment of water in order to obtain clean drinking water. The use of water disinfection as a public health measure reduces the spread of diseases. This research paper examines water quality assessment of ground and surface water samples obtained from lkole campus of the Federal University Oye-Ekiti (FUOYE). The obtained stream water was tagged Sample A, and the ground water (borehole) was tagged Sample B. These two constitute major so...
ABSTRACT This project is designed to determine households' access to domestic water supply via mechanical and non-mechanical energy system in Usin, Ikole local government area Ekiti State Nigeria, in terms of quality and quantity as the importance of adequate safe water supply to human health cannot be over emphasized. However, safe/improve water supply to most Nigerian cities is still inadequate. In the study area the relationship between water quality the degree of water source protecti...
ABSTRACT Assessing the geotechnical parameters helps in improving the soil settlement which usually causes damage to the civil structure. Compaction is one of the most important and routine engineering techniques, performed to assure the safety and stability of soils. In this study, geotechnical investigations at the lkole campus of Federal University Oye-Ekiti, Ekiti State are carried out for undisturbed and ·disturbed samples obtained at five (5) specified locations and at a depths of t...
ABSTRACT In this study, concrete mixtures were tested to effect of basalt and limestone as coarse aggregate and evaluate their efficiency on fresh and hardened concrete to achieve the design compressive strengths of [25N/mm2]. By using different proportions is 25%, 50%, 75% and100 %from the weight of coarse aggregate. The study was carried out for 6 types of concrete mixes designed by British Standard, compressive strength of concrete and workability were measured in the reconstruction of ma...
ABSTRACT The construction industry is considered one of the most hazardous industries, not only in developing countries but also throughout the world due to its unique nature. This makes more attention to construction safety to improve the safety performance of construction companies. This research aims to identify the factors affecting the construction safety and to establish rules to assess and improve the construction safety of construction companies. The questionnaire design is composed ...
ABSTRACT The production of concrete as a civil engineering material is highly dependent on the availability of its constituent materials. However, most of these materials are no more readily available. In order to solve this problem, many researches has been carried out on the use of agricultural waste as construction material, one of this material is Empty Palm Oil Fruit Bunch Ash (EPO - FBA). (EPO - FBA) is an agricultural waste material which is gotten after burning empty palm oil fru...
ABSTRACT This research project aims at classifying and determining the strength characteristics of soils along Faculty of Engineering road, Federal University Oye Ekiti, lkole campus. The road spans about 338m. The relevant soil tests include; particle size analysis, consistency limits (liquid, plastic, and shrinkage limits), natural moisture contents, specific gravity, compaction test, consolidation and shear strength tests. Liquid limit (LL) is defined as the moisture content, in perc...
ABSTRACT Most people living in rural communities, have no access to good domestic water for consumption. The inhabitants depends on rain water, well water and sometimes surface water for consumption. Improper treatment of water gotten from these sources, can lead to the spread of water borne diseases, because, sometimes the water gotten from these sources are turbid. Although, some inhabitants use alum to treat the water so as to make the water clear. But excessive usage of alum to trea...
