RheoTEC Z-60 is a first-of-its-kind workability-retaining admixture that provides a distinct mechanism for achieving flexible degrees of workability retention without retardation. This unique admixture technology allows concrete producers to create the optimal admixture system for changing and fluctuating regional raw materials, environmental conditions, and project requirements. As a result, producers can consistently deliver quality concrete mixtures and achieve more cost-effective and efficient operations.
