MNC-HHJ Description MNC-HHJ is a ready-to-use aqueous solution of hydroxylated organic compounds. Ingredients are factory premixed in exact proportions to minimize handling, eliminate mistakes and guesswork.It's Comply with GB8076-1997 and GB50119-2003. Uses MNC-HHJ retards the initial and final set of concrete. It will extend the initial setting time of portland cement concrete by 2 to 3 hours at 21 degree C. MNC-HHJ is used wherever a delay in setting time will insure sufficient delivery, placement, vibration or compaction time, such as in: Hot Weather Concreting. Transit Mix Concrete Prestressed Concrete MNC-HHJ 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. Advantages Massive concrete/cast concrete Roller-Compacted Concrete Concrete engineering under hot weather Large area construction Avoid plastic shrinkage cracks during cold weather Extend placement and long-haul applications Long placed or long transported concrete Self-leveling concrete with no agitation Slip-form or drawplate construction concrete Extending concrete setting time High strength and high performance concrete. Water-Reducing Properties Along with set retardation,MNC-HHJ provides water-reduction (typically >=18 %) in a concrete mix. This water-reducing action of MNC-HHJ produces greater plasticity and workability in the fresh concrete and the strength and permeability of the hardened concrete are measurably improved.MNC-HHJ is designed for use on jobs where high temperatures or extended setting times are the prime factors. It is recommended only when the primary purpose is to delay and control the setting time of concrete. Addition Rates Recommended Addition rate: Add 1.0% for concrete. Direction Not suitable for the concrete construction under day lowest temperature 5 degree C. Not suitable for being solely used in the concrete that require early strength and steam conserving. Not suitable for being solely used in the lean concrete. Test before used in anhydrite, dross or similar industrial waste cement Package, Storage & Handling PP.bags inner lined with plastic bag, 25kg, 30kg, or 40kg per bag. Keep from damp. Guarantee period is 3 years
