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.

Typical variations in the amount of bulking with changes in moisture content for
fine and coarse sand are illustrated in Fig. 2.3. The finer the sand, the higher the
bulking. Maximum bulking in coarse sand may be about 15 percent, and in fine ...
A lower fineness modulus of fine aggregate, denoted by a smaller number,
indicates a larger percentage of finer materials (generally, fine sand); similarly, a
higher number means fewer finer particles or plenty of coarser particles (
Use the following mix proportions: Volume of cement = Vc Volume of lime = 0.5
Vc Volume of sand = 4.5 Vc Assuming a yield of 1 ft3 of mortar for 1 ft3 of damp
loose sand, for 1 ft3 of mortar, Vs = 1 ft3 Vc = — = 0.222 ft3 For 100 ft3 of mortar,
