According to chemical properties, what are the three types of building materials?

Building materials are divided into three categories according to their chemical properties: organic materials, inorganic materials and composite materials.

1, inorganic material

① Metal materials

Ferrous metal materials-steel, iron

Non-ferrous metal materials-aluminum, copper, alloy

② Non-metallic materials

Natural stone-marble, granite

Ceramics and glass-bricks, tiles, sanitary ceramics, glass

Inorganic cementitious materials-lime, gypsum, water glass

Mortar and concrete-cement, mortar and concrete

2. Organic materials

Wood, asphalt, plastics, paints and coatings

3. Composite materials

(1) Metal and nonmetal composite reinforced concrete and steel fiber concrete

② Organic and inorganic composite materials-FRP, asphalt concrete and polymer concrete.
