| APPLICATION
1. Widely used in pre-cast & deposit concrete. armored concrete,
pre-stressed reinforced concrete and fly-ash-cement concrete. Compatible
with Portland cemen, normal Portland cement, Porland slag cement,
fly-ash cement and Portland pozzolanic cement etc.
2. Suitable for selt-cured concrete and its formulations. It has
remarkable effects of water reduction and enhancement, especially
at the early stage. The modulus and site utilization can be improved.
PROPERTIES,FEATURES & CHARACTEISTICS
1. Appearance: Pale powder. Non-poisonous, odorless, non-flammable
and non-corrosive to steel bars.
2. The combined early-strength powdery agent can improve early strength
and save cement.
3. At 0~20℃ compression strength can be increased by 80% on the
1st day,60% on the 3rd day,30% on the 7th day and 15% on the 28th
day when the agent is added at 2%.
4. 12% of water can be reduced when it is applied to normal superplastic
concrete at 2%.
5. After application, all physical properties of concrete can be
improved to a certain extent.
6. 10% of cement will be reserved when it is applied as a condition
of blending in which collapsibility and strength are fixed aforehand.

RECOMMENDED BLEND DOSAGE
The blend dosage normally ranges from 2 %.The standard blend dosage
is established at 2%.
DIRECTIONS
1. The powdery agent can be agitated together with cement. Accurate
measurement is essential.
2. A 30-second agitation is required to achieve good homogeneity.
PACKGING,TRANSPORTATION AND STORAGE
1. Woven fabric bag with plastic liner.Net weight:25kg 0.13 or 50kg
0.25.
2. Cautions should be taken to prevent from 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 expration, 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.
