Conch Cement was selected as one of the top ten typical cases in Anhui Province!

Recently, Anhui Province released ten typical cases of strengthening total quality management by chief quality officers of enterprises in 2025, and Wu Tiejun, Anhui Conch Cement Co., Ltd., successfully selected the case of "Establishing a Quality Control System for Innovative Research and Development of Low Carbon and High Performance Cement".

The Chief Quality Officer is the first person responsible for the quality safety, quality development and quality infrastructure capacity-building of enterprises. Implementing the Chief Quality Officer system in enterprises is an important measure to implement the Outline of Building a Strong Quality Country and to promote enterprises to strengthen total quality management. Wu Tiejun, the chief quality officer of

the company, led the establishment of a cross-functional research team to tackle the quality of low-carbon high-performance cement in conjunction with Baowu Environmental Science. Establish a quality control system for innovative research and development of low-carbon high-performance cement, adopt the quality technology innovation cycle method (target positioning, technological innovation, failure mechanism research, process optimization, continuous improvement), successfully develop low-carbon high-performance cement with mineral powder content higher than 75%, break through the current product standards, and adapt to large-scale industrial applications. Compared with P.O42.5 cement, the carbon emission of low carbon high performance cement is reduced by 50%. Based on Rosin-Rammler-Bennet (RRB) model, the key characteristic parameters of particle size distribution of ultra-fine ore fines with wide distribution were determined, and the cumulative particle size distribution curve of ultra-fine ore fines was obtained. The characteristic particle size of slag powder of low carbon slag cement is less than 7. 5 um, the uniformity coefficient is greater than 1, the early strength of cement is higher than 22 MPa, the compressive strength of 28 d is higher than 52 MPa, and the water requirement of standard consistency is less than 30%, the comprehensive performance of the product is significantly improved.
