Polycarboxylate plasticizer significantly improved the flowability with the increase in dosages. However, higher dosages of polycarboxylate (> 6% of cement content) increased the setting time and that can affect the early strength of pastefill. Polycarboxylate dosage ranging from 2 to 6% can be ideal for mix with low solid content (73-75%).

1 Zinc ores are dug from underground mines using conventional blasting, drilling, and hauling techniques. The ores occur as zinc sulfide (also called sphalerite), zinc carbonate (smithsonite), zinc silicate (calimine), and in compounds of manganese and iron (franklinite). Zinc ore is sometimes mined in conjunction with silver or lead ores.
