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.

Lightweight Aggregate. Lightweight fine aggregate is any aggregate with bulk
density less than 70 pcf (1120 kg/m') and lightweight coarse aggregate is any
aggregate with bulk density less than 55 pcf (880 kg/m3). Lightweight aggregates
But present codes limit the use of fibers essentially to nonstructural and non-load
bearing applications, except for use in slabs-on-grade and pavements. 3.12.4
Lightweight Concrete Lightweight concrete is concrete with an air-dried unit
Workability is a concern in the mix design of lightweight concrete. Lightweight
aggregates, since they are very porous, absorb mixing water, and may continue
to absorb for several weeks after construction. It is necessary to wet these ...
