Slow down the hydration of cement
Overcome accelerating effects of higher temperatures
High application
Prolong setting time
Description
JK-06 SG
referred to as retarder, it is a set-retarding admixture, and it can
slow down the hydration of cement
,
prolong set time
, and
extend the working life of concrete for long periods
without any negative influence on the concrete quality. It complies with ASTM C 494, Type B, GB8076-2008 and GB50119-2003.
Uses
JK-06 SG is beneficially used
in hot weather
conditions in order to
overcome accelerating effects of higher temperatures.
It can be
widely applied in large masses of concrete
. Freshly batched concrete for long hauls, shot concrete, and cast concrete.
Advantages
Extending concrete initial setting time for proper finishing without cold joint during hot weather.
Increasing the workable time of concrete up to several hours.
Providing flexibility in planning and scheduling of concrete pours.
Applicable for massive concrete, cast concrete and large area construction.
