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 ...
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...
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...

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...
Respond of Concrete pond Raised Clarias Gariepinus Fed Diet Containing Different Inclusion Level of Cow Tripe Epithelial Waste AbstractThe study examined the effect of Cow Tripe Epithelial Waste (CTEW) on the growth performance, nutrient utilisation and survival of advanced fry Clara’s gariepinus raised in ten homestead tanks (3m x 1.5m x 0.006m) for ten weeks. Each tank was-stocked with 100 advanced fry with initial average weight of 0.68 +- 0.55g. The diets were isonitrogenous 40% crude p...
ABSTRACT The study sought to trace the history of set design in Ghana through the study of some selected productions of the Concert Party, the National Theatre and the Efua Theodora Sutherland Studio. The qualitative research design was employed for the study. Two sampling techniques were employed to gather data for the research; purposive sampling technique was used to select a total of 12 respondents for the study, and sequential sampling technique was used in selecting the documents for an...
There has been a deteriorating academic performance in Mathematics in the region. When children join class one from pre-school they usually have some basics about numbers. It is from this stage where teachers in Secondary one start introducing new concepts to the learners as well as introducing new symbols used in mathematics at that level. Children in lower Secondary are in concrete operational stage, where child canreason logically about concrete events and classify objects into differe...
ABSTRACT The design of proposed Modern Bus Terminal at Obalende employs the use of thin-shell concrete structures in order to provide maximum space use. The study adopts a combination of primary and secondary data which were obtained through review of relevant literature and case studies and also interview of stakeholders at the intended site. The obtained data were properly analyzed and infused into the proposed design for a properly functional bus terminal with proper circulation....
ABSTRACT Twenty-four weaner pigs were used in a study to evaluate the response of weaner and grower pigs to diets containing graded levels of toasted soybean hull (SBH).In experiment 1(growing phase), twenty-four male hybrid (large white x landrace) weaner pigs, about 6 weeks old, weighing 5.92-6.85kg were randomly divided into four groups of six pigs each using a completely randomized design (CRD). Each group was randomly assigned to one of the four diets (1, 2, 3 and 4) containing 0% (contr...
