T/JSJTQX 52-2024 Carbon fixation and micro powder regeneration

Scope

Scope: This document specifies the classification, technical requirements, test methods, inspection rules, packaging, marking, storage, and transportation of carbon sequestration and recycled micro-powders. This document applies to carbon sequestration and recycled micro-powders used as admixtures in the preparation of cement concrete, cement mortar, and their products. Main technical content: The main technical content of carbon sequestration and recycled micro-powders: The dual-carbon goal is a national strategy, and the building materials industry is a major carbon emitter. Using recycled micro-powders as admixtures to replace part of cement in the preparation of mineral admixtures has significant carbon reduction benefits, and extensive research has been carried out. Using carbon sequestration and recycled micro-powders as admixtures not only directly sequesters carbon dioxide, but also realizes the value-added utilization of recycled micro-powders, avoids environmental pollution caused by recycled micro-powders, and reduces cement consumption, achieving multiple carbon reduction objectives and meeting the requirements of green development in the concrete industry. This document specifies the technical requirements, test methods, inspection rules, and other content of carbon sequestration and recycled micro-powders, which is of great significance for improving the standardization and standardization of the application of carbon sequestration and recycled micro-powders in highway engineering.
