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.

Fly Ash. A byproduct from the burning of powdered coal in electric generating
power plants, fly ash (also called pulverized fuel ash or pfa) is collected in the
dust-collection systems (electrostatic or mechanical precipitators) that remove ...
high-calcium) fly ash, in which the CaO content is more than 10 percent and can
be as high as 30 percent, is produced from burning subbituminous coal or lignite.
Class F fly ash possesses little no cementing property, but in a finely divided ...
Improved resistance to sulfate attack • Reduced permeability • Improved
workability and pumpability • Economy Typically, fly ash is used to substitute for
up to about 20 percent of portland cement in building construction, albeit as much
