T/XJCETS 003-2024 3D printing concrete with recycled fine aggregate

Scope

Main technical content: "Recycled Fine Aggregate for 3D Printing Concrete" is based on current additive manufacturing-related standards, concrete-related standards, and concrete inspection and testing-related standards. It specifies requirements for the classification and specifications, requirements, test methods, inspection rules, marking, storage, and transportation of recycled fine aggregate for 3D printing concrete. The main technical content includes: 1. Classification, application scope, and specifications: Referencing current national and industry standards, and combining with the actual characteristics and application scenarios of 3D printing concrete, the classification, application scope, and specifications of recycled fine aggregate for 3D printing concrete are specifically subdivided. 2. Particle size distribution and material content: Referencing current national and industry standards, and combining with the technical characteristics of 3D printing concrete, the particle size distribution is adjusted, and requirements are set for material content. 3. Test methods: For the specific performance requirements, based on current national and industry standards, and referring to tests, detailed requirements are set for indicators such as particle size distribution, material content, mechanical properties, and printability. 4. Inspection rules: Based on test results, combined with factory and type inspections, the conformity of recycled fine aggregate for 3D printing concrete is determined. 5. Provisions are made for the marking, storage, and transportation of recycled fine aggregate for 3D printing concrete, and specific requirements are proposed.
