The green properties of pellets with limestone plus bentonite Gr. Code A3 and calcined lime Gr. Code B1 is shown in Table 8. Calcined lime pellet shows higher green compressive strength and drop strength than the limestone added pellet though no bentonite has been used. This is because of the hydration of calcined lime form CaOH 2.
