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.

Manufactured sand is produced by crushing stone, gravel, or air-cooled blast-
furnace slag, and is characterized by sharp and angular particles. Gravel or river
gravel consists of materials with round and smooth edges and of size varying ...
Coarse aggregate consists of rounded river gravel, crushed stone, or
manufactured aggregate with particles of size equal to or larger than 3/16 in. (
4.75 mm). Gravel is naturally rounded aggregate of particles larger than 1/4 in. (
6.35 mm), and ...
Coarse-grained soil is gravel if more than half of the coarse fraction is retained on
a No. 4 sieve (4.75 mm), and is sand if more than half the coarse fraction is
between No. 4 and No. 200 sieves. Gravel is further subdivided as clean gravel
