EUNISHRINK ECLIPSE is a liquid admixture for concrete (or virtually any Portland cement based material) which dramatically reduces the materials shrinkage due to drying. EUNISHRINK ECLIPSE contains no expansive material, but instead acts chemically to attach the primary mechanism causing shrinkage. Concrete containing EUNISHRINK ECLIPSE at a dosage of 2% by weight of cement has been shown to reduce shrinkage, as measured per ASTM C157, by as much as 80% at 28 days, and up to 50% at one year or beyond. This level of shrinkage reduction, in well-proportioned concrete mixtures utilizing quality materials has been demonstrated to eliminate cracking due to drying shrinkage in fully restrained concrete. One liter of EUNISHRINK ECLIPSE weighs approximately 0.93 kg.
EUNISHRINK ECLIPSE may be used in any concrete, but will provide the most valued in structures and environments where cracks due to drying shrinkage are prevalent and the repercussions are most severe. Some examples of applications where this is true are bridge decks, parking garages, marine structures, containment structures and high performance floors.
With other admixtures: EUNISHRINK ECLIPSE is compatible with all conventional air entraining agents, water reducers, and midrange water reducers, superplasticizers, set retarders, accelerators, silica fume admixtures and EUNICOR DCI corrosion inhibitor. Precaution should be taken to avoid mixing EUNISHRINK ECLIPSE with other admixtures before they enter the concrete. However, once they have been separately added to the mixture, the products will not exhibit any incompatibility. EUNISHRINK ECLIPSE does have minor retarding properties (set times are typically extended less than one hour). If used in combination with other products exhibiting retarding properties the net retardation may be more than the simple additive eect of the two products used separately
