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.

and durable bond with the masonry units and with the reinforcement. The
capacity to bond individual units is measured by the tensile bond strength of
mortar, which is related to the force required to separate the units. It is important
to note that ...
Tests have shown that the tensile bond strength of mortar — which estimates the
ability of mortar to form a strong, complete bond with the units — is related to the
flow, as shown in Fig. 4.10. An increase in flow is generally accompanied by an ...
The spacing of ties in running bond construction is 24 in. (61 cm) in the horizontal
direction and 16 in. (40 cm) in the vertical direction. A hollow unit masonry does
not require ties. 4.3.1 Types of Bond As explained, the bond (also called pattern ...
