DESCRIPTION

This CCPA standard specifies the performance requirements of Structural Concrete and is in accordance with GB/T 50476 Standard for Design of Concrete Structure Durability. In view of the main problems and current situation in concrete engineering, this specification summarizes the successful experience of the development of concrete materials and engineering technology at home and abroad in recent years. According to the concept of "concrete engineering", it puts forward the requirements of concrete performance, the selection of raw materials, the principle of mix proportion design, the regulations of production quality management and construction implementation.
