Classification Of Building Materials

1. Building materials may further be classified as inorganic and organic building materials.
   • Inorganic materials consists of mud, cement, lime, gypsum, steel
   • Organic materials such as wood and biomass.
2. Another classification based on technology for building materials spanning from production to application is
   • Binders based on cement, lime, pozzolanic and polymeric materials
   • Building components such as natural building stones, mud bricks, stabilized soil bricks, burnt clay bricks and blocks, concrete and pozzolanic blocks, organic fibres and various roofing and structural materials
   • Water proofing compounds and sealants
   • Paints, painting materials and coatings
3. A classification that appears to be more suited to the stage of industrialization in developing countries is
   • Building materials for basic construction
   • Special purpose materials
   • Protective and decorative materials
4. Based on the improvements made on traditional materials for improved performance, a group of traditional material with innovations has emerged. These are called-innovations in traditional material. The introduction of a number of materials as new alternatives is called as new alternatives building materials.Therefore, based on the stage of developments brought into building material generation, building materials are classified as
   • Conventional/traditional materials
   • Innovations in traditional materials
   • New and alternative materials
5. Classification based on Basic Construction
