Different mixing sequences of fiber, water, and gypsum affect the distribution of fibers in the gypsum matrix. Methods of adding fiber to the gypsum matrix can be categorized as pre-mixing, co-mixing, and post-mixing methods. In this experiment, four fiber mixing methods were designed according to ISO 91.100.40, as shown in Fig. 2.
