Consult our Design Advantage team This approach produced concrete that would withstand delays in setting time and yielded high strengths with superior workability and pumpability, without exhibiting any segregation due to high initial slump. GCP also supplied DARATARD®, a specially developed set controller for mixes requiring very good slump retention. The high range water-reducing admixture, a product within the ADVA® family, provided excellent slump retention and water reduction.

To meet the exacting slump retention requirement of eight hours for the retail design, GCP worked with the concrete producer to develop a mix using a combination of superplasticizing and special set control admixtures for extended slump retention.
