Review meeting of CCPA standard Technical Code for Application of Ferronickel Slag Powder in Concrete was held by CCPA and CBMF on October 17, 2023. 21 representatives from scientific research and architectural design institutes, colleges and universities, industry associations, production enterprises and users attended the meeting, of which 15 were members of 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 technical indexes are advanced and applicable and the standard reaches domestic advanced level in general. Finally, the CCPA standard was approved by unanimous approval.

On the basis of domestic research and basic experimental verification, Technical Code for Application of Ferronickel Slag Powder in Concrete has comprehensively summarized the relevant research results and engineering practice experience of the application of ferronickel slag powder in concrete in recent years in China. It specifies the technical indicators and inspection methods of ferronickel slag powder used as concrete admixture, and proposes the mix design requirements and methods, preparation and construction requirements, and quality inspection and evaluation standards of ferronickel slag powder concrete. The implementation of this standard will be of great significance for standardizing and promoting the application of ferronickel slag powder concrete.
