Civil Engineering Materials
This book deals with properties, applications and analysis of important materials of construction/civil engineering. It offers full coverage of how materials are made or obtained, their physical properties, their mechanical properties, how they are used in construction, how they are tested in the lab, and their strength characteristics--information that is essential for material selection and elementary design. Contains illustrative examples and tables and figures from professional organizations. Considers all common materials of civil engineering/construction--and looks at each in depth: e.g., physical properties, mechanical properties, code provisions, methods of testing, quality control, construction procedures, and material selection. Discusses laboratory testing procedures for selected tests--provides step-by-step descriptions of laboratory test procedures to determine properties of materials. All test procedures are based on relevant ASTM specification. For Civil Engineers, Construction Engineers, Architects, and Agricultural Engineers.

Ultimate Figure 1.5 Stress-strain diagram. point of departure of the curve from the
straight line is difficult to determine; for this reason, for most materials, the elastic
limit (proportional limit) is taken as the yield point of the material.
Various types of steels have been used in reinforced concrete ranging from soft
steels, with yield strength of 30 ksi (207 MPa), to hard steels, with yield strength of
60 ksi (413 MPa). Today, reinforcing steel is manufactured to meet the ...
Yield strength is the stress at which the material exhibits a specified limiting
deviation from the proportionality of stress to strain. EQUIPMENT: Tension testing
machine, wedge grips, micrometer, extensometer. SAMPLE: Standard 0.5-in.
