All variations of the Admix C-Series contain the same amount of reactive chemicals at their prescribed dosage rates and provide the same waterproofing and durability performance characteristics.

Xypex Admix is blended into the concrete mix at the time of batching to waterproof and protect concrete from the start. It outperforms other methods because of its unique ability to become a truly integral part of the concrete matrix. The Admix C-Series has been specially formulated to meet varying project and temperature conditions.

Xypex Admix C-Series is available in regular or no-fines grades (NF):

Admix C-500/C-500 NF is formulated to have minimal or no effect on setting time. Admix C-1000/C-1000 NF is formulated for concrete mix designs where a normal or mildly delayed set is desired. Admix C-2000/C-2000 NF is designed for warmer climates and projects where a slower hydration rate is typically required. Admix C-500 NF Red and Admix C-1000 Red contains a red oxide pigment as a quality assurance measure for precasters.

See Setting Time and Strength for more details. Consult with a Xypex Technical Services Representative for the most appropriate Xypex Admix for your project.

For ease of use, Xypex Admix is available in pails, bags or soluble bags.
