Abstract The study explores the investigation of the chemical composition, microstructure and mechanical properties of steel and cement mortar used in reinforced concrete. The compositions and mechanical properties of the locally produced steel were analyzed to ascertain their potential for applications for construction. Two samples of construction steels produced and used in Nigeria were studied along. The chemical compositions of these steels were determined using Solaris CCD techniques. Th...
Abstract This research is all about design, construction and preparation of cost estimate for a reinforced concrete winder stair. This type of stair is one of most important stair, use where there is no enough space. Winder stair is very common in older homes, often used as a secondary staircase where the grand staircase may have been in the entry and the winder used as an access to the kitchen, it has more visual interest. Winder stairs meander around corners. For this reason, it has gained ...
ABSTRACT The flexural performance of reinforced concrete beam specimens with polyvinyl waste powder (PWP) as partial replacement of cement is reported in this paper. Cement was replaced with PWP up to 50% by weight at intervals of 10%. The flexural parameters investigated were: the failure patterns, load-deflection characteristics, stiffness, and ultimate moments. The reinforced beam specimens used were 150 x 150 x 1000 mm, and tests were done at the curing age of 28 days. The results showed ...
PREFACE This is the presentation of an information on the detailing of structural members in Buildings. Structural detailing is a branch of structural work that transposes the idea or works f a structural engineer in working drawings for easy utilization in the building Construction works. Working drawing are produced by an architect and a structural Engineer for easy use by a Contractors. The processes of detailing put in place was in conjunction with the recommendation of the concrete ...
ABSTRACT This study is centered on the analysis of business objective and their accomplishment through effective cost control in lake concerted industry-limited Enugu. There are lots of problem that face the industry, some of which are shortage of raw materials, excessive demand, ineffective stock planning and inefficient stock management. The study therefore embarked on how the industry should form a strong stock management policy. Thereby forming a stock management committee that will monit...
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...
An inquiry on the blatant effectiveness of manure on zooplanktons and water quality in a concrete pond culture was reviewed within durations of twelve weeks. Zooplanktons were obtained using scooping net and water sample analysisdetermined using standard techniques. Result revealed a higher culture of zooplanktons using poultry manure than those from cow dungs: 10 zooplankton species belonging to Rotifera, Cladocera and Crustacea was recorded with Brachionuscalyciflorusand Brachionusleydigi, ...
effects of aggregates sizes on concrete strength
Mixing water is very vital for development of concrete and /or mortar. It can also be a source of aggressive ions in the cured concrete/ mortar. This study investigated the effect of mixing water on performance of cement mortar made from selected Ordinary Portland cement (OPC) and Portland pozzolana cement (PPC). Test cements were sampled from three local cement manufacturing plants while mixing water was randomly sampled from different construction sites in Kajiado, Machakos and Nairobi coun...
In developing processing machines for plant materials, the frictional property of the seed on structural surfaces of Mild steel (MS), Plywood (PW), Concrete (CC) and Glass (GL) is a parameter which needs to be measured. In this study, the static coefficient of friction of two Nigerian beniseed accessions (Yandev-55 and E8) were determined at moisture content levels of 5.3, 10.6, 16.1 and 22.4 per cent (wet basis). These were used as inputs into designing a beniseed oil expeller. A - 2 x 4 fac...

ABSTRACT This study examined the experimental analysis of sandcrete block production by using different sources of sharp sands in Enugu and Ebonyi State of South-East Geo-Political Zone. As a result of the increasing cost of block production, many manufacturers and builders have resorted to using samples of sharp sand from different locations without appropriate consideration of the material constituents of the samples thereby, resulting in poor and undurable concrete blocks production. In ...

CHAPTER ONE BACKGROUND TO THE STUDY 1.0 INTRODUCTION Right from when man stated to build, he has been compelled to use the locally available materials around him. Building has now become major construction material allover the world has necessitated a critical study of its constituent materials. More so, the present economic crunch calls for cost saving measures on the part of engineers/researchers involved in the management of the country’s project. Hence, the need for resea...
