| APPLICATION
It can be applied to deposit and pre-cast concrete, pre-stressed
reinforced and fly-ash-cement concrete. It is compatible with regular
Portland cement, Portland slag and pozzolanic cement. Intended for
winter operations.
PROPERTIES, FEATURES&CHARACTERISTICS
1. Appearance: Dark brown powdery agent. Non-poisonous, odorless,
non-inflammable and non-corrosive to steel bars.
2. As a combined super accelerator, it can reduce water and enhance
strength.
3. As a condition of blending where cement amount and collapsibility
are fixed, water reduction exceeds 18%. Compression strength exceeds
120%, 80%and 30%on the 1st, 3rd day and 28th day after application
respectively. At the early stage, strength can rise to desired level
in 3 days. Greater enhancement will be shown at the end . As the
result, all setting properties will be improved greatly.
4. 15% of cement can be reserved as a condition of blending where
collapsibility and strength are fixed.

RECOMMENDED BLEND DOSAGE
The blend dosage normally ranges from 2.5%.The standard blend dosage
is established at 2.5%. DIRECTIONS
1. The powdery agent can be agitated together with cement. Accurate
measurement is essential.
2. A30-second agitation is required to achieve good homogeneity.
RACKGING, TRANSPORTATION AND STORAGE
1. Woven fabric bag with plastic liner. Net weight: 25kg±0.13 kg or
50 kg±0.25 kg.
2. Cautions should be taken to prevent form being torn by sharp-ended
objects while packages are transferred or delivered.
3. It should be stored in a dedicated warehouse that is well-ventilated
and dry. It remains effective for two years. At the expiration, re-use
is allowed if the testing results fall within the established range.
In case of humidity contamination, re-use is allowed after drying
and crushing.
