Grinding kinetics of wet milled ultrafine phosphorus slag as a supplementary cementitious material
Original language description
Phosphorus slag (PS) is an industrial by-product rich in amorphous silicates and has potential pozzolanic activity, making it a viable supplementary cementitious material. However, untreated phosphorus slag has large particle sizes and a dense surface, resulting in low reactivity that limits its engineering applications. In this study, phosphorus slag was subjected to wet ball milling for varying durations. The grinding kinetics and performance evolution of the milled phosphorus slag were systematically investigated using a laser particle size analyzer, specific surface area (SSA) testing, compressive strength tests, activity index evaluation, and grey relational analysis. The results show that the double logarithm of the phosphorus slag particle size and grinding time have a good linear relationship, which can be quantitatively described by the Divas-Aliavden model. The particle size distribution can be effectively fitted by the RRB model, Swebrec model, and fractal theory, with the fractal dimension D increasing from 1.52 to 2.44, indicating the self-similarity of the grinding process. Grey relational analysis indicates that the particle size range of 3-5 mu m has the most significant positive effect on strength improvement. When the cement replacement rate reaches 40 %, the 28-day compressive strength of phosphorus slag treated by wet milling for 120 min can reach 93.2 MPa, which is 36 % higher than that of pure cement. Considering both technical efficiency and economic benefits, a wet milling time of 120 min is recommended as the optimal parameter.
