What are the three categories of civil engineering materials classified according to the basic composition?
According to the quality of points can be divided into A class, B class, C class.
According to the material is divided into inorganic materials, organic materials, composite materials, metal materials.
Inorganic materials: metal and non-metallic materials. Organic materials: composite materials: inorganic non-metallic materials and organic materials composite (steel brazing concrete, asphalt concrete, polymer concrete, polymer mortar, etc.). Plant material, asphalt material and high score material.
(1) organic materials made of organic materials, including: natural organic materials (such as wood, etc.), synthetic organic materials (such as plastic, etc.). (2) inorganic materials, inorganic materials, including: metal materials (such as steel, etc.), non-metallic materials (such as cement, etc.). (3) composite materials, organic - inorganic composite materials (such as glass fiber reinforced plastic, etc.), metal. Non - metallic composites (such as steel fiber concrete). Composite materials can be developed and a large number of applications, the reason is that it can overcome the weakness of a single material, play a composite material after the composite advantages to meet the requirements of contemporary civil engineering materials.
