Scope: The main technical content of carbon-fixing regenerated micron powder: The dual-carbon goal is a national strategy, and the building materials industry is a large carbon emitter. The use of recycled micropowder as fixed carbon dioxide to prepare mineral admixtures to replace part of cement has significant carbon reduction benefits, and extensive research has been carried out. The use of carbon-fixing regenerated micropowder as an admixture not only directly fixes carbon dioxide, but also realizes the value-added utilization of regenerated micropowder, avoiding the environmental pollution of regenerated micropowder. It also reduces cement consumption, achieves multiple carbon reduction purposes, and is in line with the green concrete industry. development requirements. This document stipulates the technical requirements, test methods, inspection rules, etc. for carbon-fixing regenerated micropowder. It is of great significance to improve the standardization and standardization level of the application of carbon-fixing regenerated micropowder in highway projects.
