混凝土的品質直接攸關工程的品質，其重要性不言而喻，預拌混 凝土廠應加強對混凝土品質的管控，確保原料品質的穩定性，同時做 好混凝土生產過程控制和出廠檢測。為解決混凝土品質管控問題，工 程會建立廠驗程序，以第三者驗證之公正客觀立場，查驗預拌混凝土 廠之混凝土性能及品質，作為各機關採行的依據。其中生產控制性低 強度回填材料(CLSM)的部份，至目前為止國內尚無明確適用的廠驗 機制與規範。 本研究以重新探討控制性低強度回填材料(CLSM)混凝土廠廠驗 機制及研擬混凝土廠分級機制發展方案為目的。透過文獻回顧及整合 分析預拌混凝土的廠驗需求與程序、相關規範及現況等，提出CLSM 混凝土廠之自主管理機制。再以多個預拌廠為例進行混凝土檢驗項目 評比，建立混凝土廠分級制度之架構與策略，以設立適當的混凝土品 質門檻，協助預拌廠整體向上提升，促進國內各項管路工程品質之水 準。;The quality of concrete is directly related to the quality of the engineering project. The ready-mixed plants should strengthen the control of concrete quality, ensure the stability of material quality, and do a good job in concrete production process control and product inspection. In order to solve the problem of concrete quality control, Public Construction Commission established a factory inspection procedure to check the concrete performance and quality of the ready-mixed plants with the impartial and objective position of the third party verification, as the basis for the various agencies. Among concrete types, the controlled low strength materials(CLSM) has not yet been clearly applicable to the factory inspection specifications. This study aims to establish the inspection mechanism of the CLSM manufacturers and to develop a classification system for ready-mixed plants. Through the literature review and integration analysis of the factory inspection requirements and procedures, relevant specifications and current conditions of ready-mixed concrete, the self-management mechanism of CLSM is proposed. Establish the structure and strategy of the ready-mixed plants classification system, set up the appropriate quality threshold, assist the overall improvement of the pre-mixing plant, and promote the quality of the domestic pipeline engineering quality.
