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.

High-alumina cement (also called calcium alumi- nate cement) is produced by
burning limestone and bauxite, and contains sintered calcium aluminate (
monocalcium aluminate, CA) instead of the calcium silicates of portland cement.
Dicalcium silicate hardens slowly and is accountable for later-age strength, the
strength increase beyond about two weeks. The hydration of silicates produces
crystalline calcium hydroxide and calcium silicate hydrate. The latter is a poorly ...
When mixed with lime, or with calcium hydroxide (a byproduct of the initial
reaction between cement and water), pozzolans produce hydrates of calcium
silicate, calcium aluminate, and calcium aluminosilicate. This reaction, between
lime and ...
