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.
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
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
Massive concrete/cast 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.
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.
Recommended Addition rate: Add 1.0% for concrete.
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
