CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE 1.0 INTRODUCTION Steel is a man-made material containing 95% of iron. The remaining constituent are small amount of element derived from the raw-material use in the making of the steel, as well as other element added to improve certain characteristics or properties of the product (Marcus, 1964). Steel reinforcement are used generally in the form of bars of circular cross-section in concrete structure. They are like a skeleton in human body. Plain concrete without steel or any other reinforcement is strong in compression but weak in tension. Steel is one of the be ... Continue Reading
CHAPTER TWO - [ Total Page(s): 10 ]CHAPTER TWO2.0 LITERATURE REVIEW2.1 NIGERIAN STEEL INDUSTRY (HISTORICAL DEVELOPMENT)Planning for the Nigerian steel industry started around 1958. Many international Organizations and consulting firms had been commissioned at various times to study the feasibility of steel plants under the aegis of the Federal Ministry of Industries In 1971 an extra-ministerial agency was established by Decree to focalize efforts required to actualize a steel plant. The agency was called ‘Nigerian Steel Development Authority†(NSDA). Under this agency organized efforts were intensified in market sur ... Continue Reading
CHAPTER THREE - [ Total Page(s): 3 ]3.3.2 Principle of OperationWith every 2 revolutions made on the hand or motor driven gear box of high mechanical advantage, a force of 20kN (2000kgf) is applied to a test piece held in the chuck pins. The force deflects the spring beam and this deflection operates a level acting on a piston in a cylinder containing mercury. It should be noted that the mercury inside the sleeve must be at zero point before the drive is made, and this can be alone using the mercury adjuster. The recording graph is mounted on a cylindrical drum connected directly to the main drive. As the mercury column advances ... Continue Reading

ELASTIC MODULUSThis is the slope of the straight line portion of each curveSpecimen 1 =(change in stress)/(change in strain) = 295/0.012 = 24583 N/〖mm〗^2Specimen 2 = 240/(0.018 ) = 13333N/〖mm〗^2Specimen 3 = 220/0.012 = 20000N/〖mm〗^2Therefore:Average elastic modulus = (24583+13333+20000 )/3 = 19305N/〖mm〗^24.1.4 ANALYSIS FOR 16mm MILD STEEL SPECIMENSi.

CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVE5.0 CONCLUSION AND RECOMMENDATION From the test carried out and the results obtained, the average yield strength for specimens diameter of 8mm, 10mm, 12mm, 16mm, 2Omm and 25mm were 79N/mm2, 225 N/mm2, 261 N/mm2, 277 N/mm2, 295 N/mm2 and 297 N/mm2 respectively. It was therefore observed that specimen of 8mm and 10m do not meet the BS8110 specification of 250 N/mm2 for mild steel.However, the analysis shows that the average ultimate strength obtained for the specimens of 8mm, 10mm 12mm, 16mm, 20mm and 25mm were 447 N/mm2, 440 N/mm2, 509 N/mm2, 512 N/mm2, 547 N/mm2 and 529 N/mm2.It ca ...
