A review meeting of the CCPA standard Technical Specification for the Application of High Volume Fly Ash Concrete was held by CCPA and CBMF on May 21, 2025. 32 representatives from scientific research and architectural design institutes, industry associations, inspection bodies, laboratories, production enterprises, and users attended the meeting, of which 16 were members of the review committee.

The main drafter introduced the standard preparation process, the collection of comments, and the test data that support the main technical requirements in the standard. The review committee reviewed all the documents, examined the standard text word by word, and put forward revisions. The review committee made conclusions that the content of this standard is systematic and comprehensive, and the technical indexes are advanced and applicable. Finally, the CCPA standard was approved with unanimous approval.

Technical Specification for the Application of High Volume Fly Ash Concrete summarizes the advanced technologies for the application of high volume fly ash concrete in recent years, and proposes the minimum fly ash content and the maximum water consumption for high volume fly ash concrete. It is conducive to reducing the temperature rise of concrete structures, improving their crack resistance, and solving the engineering problem of concrete structure cracking. The implementation of this standard will enhance the comprehensive utilization level of large amounts of fly ash in the concrete industry and improve the durability of concrete structures.
