Civil Engineering MaterialsThis 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. KEY TOPICS: 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. MARKET: For Civil Engineers, Construction Engineers, Architects, and Agricultural Engineers. |

... Voids Unit weight or bulk density ( also called dry - rodded weight , specific weight , and dry- loose weight ) is the mass of aggregate per unit bulk volume . The mass of the sample is determined in oven - dry condition ( after driving ...
Shan Somayaji. Percentage of voids 20 40 10 50 50 content is generally expressed as a percentage of total or gross volume , which is the solid volume plus the volume of voids . For example , a forty percent void content means the solids ...
... Voids . Increase in the water content increases the voids in con- crete , lowering the durability , watertightness , and ( clearly ) the compressive strength . Early theories on the strength development of concrete established a clear ...
