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.

The reaction involves the interaction of hydroxyl ions (associated with alkalis) in
cement with certain siliceous constituents of the aggregates (reactive silica). The
products of reaction, such as sodium silicate gel (also called water glass), form ...
The potentially aggressive constituents in seawater are sulfates, chlorides,
carbonates, bicarbonates, alkali metal, and magnesium ions. Magnesium sulfate,
rather than sodium or calcium sulfate, is the most common aggressive agent.
Another portion of the bar turns into the cathode, where the electrons are
consumed in the presence of moisture and oxygen, and the moisture present in
the concrete is the electrolyte that permits the movement of ions. The
