DaleaRetard 011A is a high performance, ready-to-use liquid admixture, formulated from selected purity of lignosulphonates and modified polymers. Ingredients are factory premixed in exact proportions to minimise handling

APPLICATION DaleaRetard 011A retards the initial and final set of concrete. At the usual addition rate of 300mL / 100kg cementitious material it will extend the initial setting time of portland cement concrete by 2 to3 hours at 21°C. DaleaRetard 011A is used wherever a delay in setting time is required to insure sufficient delivery, placement, vibration or compaction time, such as in:

Hot Weather Concreting

Transit Mix Concrete

Prestressed Concrete

DaleaRetard 011A is also used in special applications, as in bridge decks where it extends plastic characteristics of the concrete until progressive deflection resulting from increasing loads is completed

Water-reducing Properties Along with set retardation, DaleaRetard 011A provides water-reduction (typically 8 to 12%) in a concrete mix. This water-reducing action of DaleaRetard 011A produces greater plasticity and workability in the fresh concrete and the strength and permeability of the hardened concrete are measurably improved. DaleaRetard 011A is designed for use on jobs where high temperatures make extended setting times desirable. It is recommended only when the primary purpose is to delay and control the setting time of concrete.
