Application

Zinc sulfate heptahydrate is weak acid and can be used as a concrete retarder. It can reduce the bleeding of lean concrete and does not affect the growth of early strength. As a retarder, zinc salt is not durable enough, so it is seldom used alone. Instead, it is used in combination with organic retarder to adjust the retention rate of slump and setting time of concrete.

Packing

It is packed with polythene bag as the inner layer, and a compound plastic woven bag as the outer layer. The net weight of each bag usually is 25kg.
