89Figure 55: 19 mm polypropylene fibersWhen utilizing fibers in this research, the moisture content level of the mixture had to besufficient to achieve appropriate level of curing of cement based piers and binding betweensoil particles and fibers in case with loess based piers. The level of moisture content of loesswas adjusted to the optimum level of 19 percent in the loess and fiber pier applications.However, additional water was used when mixing loess and cement composition piers toachieve water/cement ratio of 0.5. Mix composition of fibers, loess, and cement can be seenin Figure 56..Figure 56: Loess + C(I) + fiber mix during sample preparation
