Civil engineering materials refer to all kinds of materials used in civil engineering. Engineering materials are the material basis of civil engineering. The performance and quality of engineering materials directly affect the basic requirements of firmness, applicability, economy and aesthetics of engineering. In the civil engineering cost, the material cost accounts for a large proportion, generally about 60%. If we can use the building materials economically and reasonably, reduce the loss, we can reduce the project cost and improve the economic benefits.
In the process of engineering design and construction, it is bound to be restricted by the variety and performance of engineering materials, and the emergence of new materials promotes the development of architectural and structural forms, the improvement of structural design methods and the innovation of construction technology. The progress of material science and technology promotes the development of building engineering technology; the emergence of light and high strength materials promotes the development of modern buildings to high-rise and large span. With the development of new thermal insulation materials, waterproof materials, sound-absorbing materials and various decorative materials, the functions of buildings have been improved.
All buildings and structures are made of different materials. Materials with different properties play different roles in various parts, such as structural materials should have required mechanical properties; roof materials should have thermal insulation and impermeability; ground materials should have wear resistance; materials exposed to atmospheric environment for a long time should be able to withstand wind, rain, sunlight, freezing and so on, that is to say, they have good durability. Mastering the nature of civil engineering materials is the basis of scientific design and construction.
Civil engineering materials can be divided into narrow sense of civil engineering materials and broad sense of civil engineering materials. In a narrow sense, civil engineering materials refer to all materials directly used to build civil engineering entities, which is also the content of this book. In a broad sense, civil engineering materials refer to all the materials used in the process of civil engineering construction.
