Analysis of Optimization Method for OGFC Mixture Gradation Design

Taking OGFC-13.2 (target porosity: 16%) as an example, this paper analyzes the shortages of current specifications on OGFC gradation design, and proposes an optimized design method for OGFC mixture. Then the Bailey method was used to detect whether the target mix can make the mixture constitute a skeleton structure. Finally, the rationality of new design method is verified through several conventional experiments with recommended gradation. New design method with clear thinking and good operability, can better guide the OGFC gradation design.
