Recent Announcement– Anhui Province has unveiled its 2025 list of exemplary Chief Quality Officer initiatives, recognizing Anhui Conch Cement’s Wu Tiejun for establishing a groundbreaking quality control system for low-carbon high-performance cement R&D.
Role of the Chief Quality Officer
As the primary leader responsible for quality security, development, and infrastructure capabilities, the Chief Quality Officer embodies corporate commitment to national quality strategies. The implementation of this role is a core measure in advancing total quality management under China’s Outline for Building a Quality Nation.
System Innovation and Technical Achievement
Under Wu Tiejun’s leadership, a cross-functional task force partnered with Baowu Circular Economy to develop an innovative quality management architecture for low-carbon cement. Utilizing a cyclic methodology of “Target Setting → Technological Innovation → Failure Mechanism Analysis → Process Optimization → Continuous Improvement,” the team successfully engineered high-performance cement with over 75% mineral powder content — exceeding existing product standards while maintaining industrial scalability.
Environmental and Performance Outcomes
The new cement variant reduces carbon emissions by 50% compared to conventional P.O 42.5 cement. By applying the Rosin-Rammler-Bennet (RRB) model, the team identified key particle distribution parameters for ultra-fine mineral powder, achieving a cumulative particle size curve optimized for performance. Critical metrics include:
?Characteristic particle size below 7.5 μm
?Uniformity coefficient exceeding 1.0
?Early-stage strength >22 MPa
?28-day compressive strength >52 MPa
?Standard consistency water demand <30%
Industry Implications
This breakthrough demonstrates how traditional industries can synergize quality management with ecological goals. The case offers replicable insights for decarbonizing construction materials through particle science and systematic quality governance.
