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.

3.9.4 Corrosion Alkali-silica reaction, sulfate attack, and freeze-thaw deterioration
apply to the durability of plain concrete. In concrete with reinforcing or
prestressing steel, deterioration can also be due to corrosion of the reinforcement
Enhanced electrical resistivity of concrete also helps in reducing the potential for
corrosion. Corrosion comprises two distinct phases: corrosion initiation and
corrosion propagation. The initiation phase defines the period from the
placement of ...
To protect reinforcement from chloride-induced corrosion, the depth of cover
should be about 3 in. (75 mm), although tests have shown that even a 3/4-in. (19-
mm) layer of dense, impervious concrete can provide excellent protection.
