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.

Sieve Analysis. Gradation of aggregates is determined from sieve analysis, in
which a representative sample of the aggregate is passed through a series of
sieves and the weight retained in each sieve — expressed as a percentage of the
opening size that is one-half that of the upper or twice that of the lower sieve. For
example, the No. 50 sieve has an opening of 0.3 mm, which is twice the size of
the opening of the No. 100 sieve (equal to 0.15 mm), and half that of the No.
The sieve analysis of fine aggregate is commonly carried out in a mechanical
shaker that is designed for 8 in. (203 mm) diameter round sieves; that of coarse
aggregate may be carried out in the same shaker designed for 8 in. round sieves,
