Donplast® RC500

Powder admixture for the treatment of returned concrete

Donplast RC500 is a one component, powder admixture specifically designed to treat returned fresh concrete. It is supplied in water-soluble bags that can be added directly into the drum of ready-mixed concrete truck.

Once Donplast RC500 is added to the concrete, it significantly minimizes cement hydration while rapidly stiffening the concrete. This effect converts concrete from a plastic form to a granular form, allowing it to be re-used.

Donplast RC500 enables concrete producers to provide a solution for returned concrete that does not require onsite crushing or disposal into landfills.
