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.

Increase in the fineness of cement without corresponding increase in the water
content decreases the workability. Some admixtures — such as water-reducing
admixtures or superplasticizers, and air-entraining admixtures — improve ...
Drying shrinkage is gradual, and the rate of shrinkage decreases with time.
Between about 40-80 percent of the 20-year shrinkage takes place within about
three months. At the end of one year, the rate of shrinkage drops to nearly one-
half the ...
(35 cm) may decrease typically by about 0.1 in. (0.25 cm) along the width and 0.7
in. (1.75 cm) along the depth when the moisture content decreases from 30 to 10
percent during service. To accommodate this large reduction in the depth of the ...
