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.

The striking-off operation, also called screeding, is required to even out the
surface at the specified depth. A strikeboard, usually of 2 X 4 in. (5 X 10 cm)
lumber, long enough to rest across the top of the form, is used for this operation.
A smooth finish is obtained by using a relatively hard finishing or steel trowel on
the surface. A swirl-float finish is produced for visual interest and surer footing, by
working the float — wood, aluminum, or canvas resin — flat on the surface in a ...
The prime coat also helps to consolidate the surface on which the new treatment
is to be placed and prevents the upward migration of capillary water. A well-
compacted and finished soil-cement base coarse is given a coat of asphalt
