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... Continue Reading
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...

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... Continue Reading
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...

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... Continue Reading
Abstract: This paper examined the basic engineering and geotechnical properties of poor subgrade soils using woven geotextile to stabilize it and to also deal with the problem with lime under soaked conditions, it is intended at increasing the strength and mechanical properties of the soil even in extreme conditions. This is considered to be... Continue Reading

ABSTRACT Sustaining housing development especially to the medium/low-income group of the society has become a huge challenge particularly because of the huge capital outlay required to do so. Thus, acquisition of indigenous building materials by way of Compressed Stabilized Laterite Blocks (CSLBs) has been suggested as a way out. The aim of this... Continue Reading
A MATHEMATICAL MODEL FOR PREDICTION OF THE STRENGTH OF SANCRETE CEMENT BLOCK [APPLICATION OF HENRY SCHEFFE’S AND OSADEBE’S CONCRETE OPTIMISATION THEORY] Abstract Sandcrete blocks are prismatic units manufactured from lean (sand-cement) mortar mixes and are the predominant walling materials used in buildings in Nigeria and other countries....

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... Continue Reading
ABSTRACT A lateritic soil classified as sandy clay or (CL) and A-7-6 (5) according to Unified Soil Classification System (USCS) and AASHTO classification system respectively,was treated with up to 10% pulverized steel slag (an industrial waste product) by dryweight of soil. Elemental and chemical analysis of the steel slag was determined using... Continue Reading
ABSTRACT This study examined the effects of effluent discharges from various point-loads on a purposively selected receiving river, the self-recovery ability of the river and the treatability of both the discharges and the receiving stream in a heavily industrialized community. The work involved field survey of industries producing and discharging... Continue Reading

ABSTRACT The one- time held historical and cultural reputation the Enugu city was the cleanest city in Nigeria is fast fading away. in its place great Pyramids of refuse are found at every junction and street corner begging for removal despite of public out cry, public enlightenment programmes on personal hygiene and environmental health. The... Continue Reading
ABSTRACT This case study is “comparing the strength of blocks made from: cement stabilized laterite blocks, cement stabilized red earth blocks and sand, red earth and laterite blocks and mud blocks dried in the kiln. This project implement the following analysis (1) To effect ... Continue Reading
ABSTRACT Black cotton soil classified as an A-7-6 (24) soil on AASHTO classification collected from new Marte area of Borno state was modified with up to 4% cement and LBWA up to 8% by weight of the soil. The effect of locust bean waste ash (LBWA) on the cement modified soil was studied with respect to particle size distribution , Atterberg... Continue Reading
ABSTRACT This research work focuses on the development of Iso-safety design charts for flexural design of flat slabs at predefined reliability levels in accordance with Eurocode 2 (2004) design criteria. Constitutive models for reinforcing steel and concrete were selected in accordance with the Eurocode 2 design requirements and subsequently the... Continue Reading
ABSTRACT In this thesis the reliability analysis of reinforced concrete bridge decks subjected to high cycle fatigue was undertaken. A simply supported (single span) reinforced concrete bridge deck was specifically used for the investigation. The statistical models of capacity loss were derived. The uncertainties in structural resistance and the... Continue Reading
ABSTRACT The concept of public participation and how it can be incorporated in transport planning was studied. Current planning methods and steps were reviewed, and a tool which incorporates public participation in planning (questionnaire) was developed. This study was carried out using questionnaires that incorporate socioeconomic factors that... Continue Reading
