Briefly describe the technical requirements of civil engineering for the use of its building materials and explain its reasons
As the pavement material, asphalt mixture, wear resistance, tensile strength, high temperature stability and durability, etc .; as the roof Waterproof material, the need for tensile strength, elongation at break, low temperature flexibility, impermeability, anti-aging properties
For example, as the structure of reinforced concrete requires mechanical properties of the requirements: such as strength, elastic modulus, shrinkage and so on; physical properties, apparent density, impermeability and durability
Because the building materials in the civil engineering are used for all aspects of structure, finishes, insulation, filling and so on, there is a need for physical and mechanical technical requirements for building materials to meet the practicality, functionality, durability and beauty of buildings or structures The need for sex.
