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.

3.9 DURABILITY A concrete structure will normally remain durable if • the cement
paste structure is dense and of low permeability; • under exposed conditions, it
has entrained air to resist freeze-thaw cycles; • it is made with graded aggregates
3.10.2 Mix Design Procedure The trial mix design procedure is formulated to
achieve a mix that will satisfy the strength, durability, and workability
requirements of concrete as closely as possible. The procedure can be
summarized as follows: 1 ...
5.5 TREATMENT AND DURABILITY Wood is a very durable construction material
and lasts for centuries if it is well seasoned and kept in a dry place, immersed in
water, or buried in the ground. However, when subjected to fluctuations in ...
