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.

It should set within a reasonable amount of time and hydrate in a manner that
ensures adequate strength when the structure is put to service. Workability. All
aspects of fresh concrete — those associated with several tasks, from the

An increase in the amount of fine aggregate and the addition of more water
improve workability. An excessive amount of any size fraction results in poor
workability. Rounded grains of natural sand produce better workability than do
3.6.2 Factors Affecting Consistency and Workability As mentioned, a number of
factors influence the consistency and workability of fresh concrete. A summary is
provided in the following paragraphs. Workability is relatively insensitive to the ...
