Several materials are required for construction. The materials used in the construction of Engineering Structures such as buildings, bridges and roads are called Engineering Materials or Building Materials. They include Bricks, Timber, Cement, Steel and Plastics. The materials used in Civil Engineering constructions can be studied under the following headings.
  1. Traditional materials
  2. Alternate building materials
  3. Composite materials
  4. Smart materials
It is necessary for an engineer to be conversant with the properties of engineering materials. Right selection of materials can be made for a construction activity only when material properties are fully understood. Some of the most important properties of building materials are grouped as follows.  
Group Properties
Physical Shape, Size, Density, Specific Gravity etc.,
Mechanical Strength, Elasticity, Plasticity, Hardness, Toughness, Ductility, Brittleness, Creep, Stiffness, Fatigue, Impact Strength etc.,
Thermal Thermal conductivity, Thermal resistivity, Thermal capacity etc.,
Chemical Corrosion resistance, Chemical composition, Acidity, Alkalinity etc.,
Optical Colour, Light reflection, Light transmission etc.,
Acoustical Sound absorption, Transmission and Reflection.
Physiochemical Hygroscopicity, Shrinkage and Swell due to moisture changes
