Commonly used building materials - relationship between material structure and properties. Masonry materials - stones, bricks, blocks; Refractory products; Timber and wood based products - Classification, properties, testing and selection criteria.
Binding materials (Lime, gypsum, cement) and Mortars - types, properties, tests. Concrete – Aggregates – Mechanical and Physical properties and tests – Grading requirements – Water quality – Admixtures. Properties of concrete in fresh and hardened state – workability – segregation and bleeding – tests on workability and strength. Stress – strain characteristics and elastic properties – shrinkage and creep. Mix proportioning (B.I.S method) – nominal mixes.
Metals – Structural steel - properties and uses - sections – Reinforcing steel – use of Aluminium. Bituminous materials – types and properties of asphalt, bituminous concrete. Modern construction materials – Paints, Glass, Ceramics, Polymers and plastics, Adhesives, Composites and smart materials. Recycling of industrial waste as building materials.
