Scope

Scope: This indicator system specifies the terms and definitions of clean production for concrete admixtures, the evaluation indicator system, data collection and calculation methods, and the assessment method for clean production grades. This indicator system is applicable to clean production audits of concrete admixture production enterprises, the assessment of clean production potential and opportunities, the evaluation of clean production performance, and the establishment of a clean production performance announcement system. It is also applicable to the formulation of environmental management systems such as environmental impact assessments and pollution discharge permits. Main technical content: 1. Classification and selection of evaluation indicators 2. Baseline values of evaluation indicators and their explanations 3. Clean production requirements for polycarboxylate-based water-reducing agents 4. Clean production requirements for naphthalene-based high-efficiency water-reducing agents 5. Clean production requirements for lignin sulfonate water-reducing agents 6. Clean production requirements for rosin hot polymer air-entraining agents 7. Clean production requirements for quick-setting agents 8. Clean production requirements for expansion agents (calcined) 9. Clean production requirements for composite admixtures 10. Data collection and calculation methods 11. Assessment method for clean production grades
