Factory Price 98% PCE Powder Polycarboxylate Superplasticizer AS Concrete Motar Admixtures
-----XRT-PM
Polycarboxylate Superplasticizer Powder is the newest generation superplasticizer in domestic and abroad.
Comparing with PNS and other superplasticizer, PCE superplasticizer has many characteristic advantages in technology and performance as following:
(1) low dosage, high rate of water reducing;
(2) keep concrete good slumption retention;
(3) good compatibility with cement;
(4) small shrinkage of concrete to keep the stability of volume and durability;
(5) environmental in production and usage. Base on above advantages, PCE superplasticizer attract the attention from
engineering field and has been widely used in some important projects. Predictably, base on above advantages,
PCE superplasticizer will be the main trend in the market.
The recommend dosage of superplasticizer for concrete: 0.1-0.25% base on cement quantity.Solid contents of PCE powder is 98%. Normal dosage is 0.12%-0.3%.
◆ when dosage is 0.06%, it has 12% water reducing rate and 23%
strength growth, this beyond the performance of common pumping
agent in market.
◆ when dosage is 0.1%, performance beyond that of PNS and
Melamine. But when dosage is below 0.14%, its good performance is
not obvious.
◆ When dosage is above 0.20%, it is excellent in concrete fluidity and pumping performance.
◆ Therefore, the best dosage is recommended as 0.12-0.24%; when making concrete with high grade, big dosage of
flyash or superfine slag powder or other special requirements, dosage can be expanded to 0.3-0.5%. Test state that
there is no cohesion and bleeding in concrete even the dosage expand to 0.5%, and its water-reducing rate still
increase . But air content increase, setting delay, strength decrease.

(1) It makes cement good dispersibility and fluidity in low dosage.
(2) When dosage is from 0.12% to 0.22%, the cement paste fluidity grows obviously.
(3) There is no loss of fluidity within 1 hour in cement paste.
(4) The fluidity of PCE powder is 2 times of other superplasticizer in market.
◆ Motar Performance
(1) It is homologous between water-reducing rate of motar and fluidity of cement paste.The more fluidity of cement
paste, the more water-reducing rate of motar.
(2) Water-reducing rate increases fast and high when the dosage increase. When the dosage is same,the water-
reducing rate of PCE powder is 35% higher than that of other superplasticizer in market.
(3) Due to the influence from the admixture and sand coarse aggregate, Water-reducing rate in concrete is different
from that of motar.When the the admixture and sand coarse aggregate are in favour of the concrete flow, the
water-reducing rate of concrete is higher than that of motar.
(4) It has antifreezing performance when temperature is above -5℃. So it can be used in antifreezing concrete.
◆ Concrete Performance
(1) Strength and Mix Proportion of Concrete(kg/m3)
Water | Cement | Sand | Aggregate | |
Standard | 200 | 330 | 712 | 1163 |
Dosage 0.16 in PCE powder | 138 | 327 | 734 | 1198 |
Ratio of Compressive strength growth(standard)as following %:
1 day | 3 days | 7days | 28days | 90days |
220 | 190 | 170 | 170 | 170 |
(2) Other performance of Concrete
Ratio of bleeding rate | Ratio of Shrinkage | Initial setting time | Final setting time | Air content |
≤85% | ≤75% | +40~80 mins | +0~10 | ≤3% |
Comparing with standard concrete ,the bleeding rate and shrinkage rate of concrete with PCE powder is lower ,Initial setting time prolong 60 minutes , final setting time is similar, air content is controlled in 2-4%.
◆ According to the design of concrete, adjust quantity the water or sand to make sure the slumps, strength, setting all
to meet with requirements base on the required dosage of admixture.
◆ It apply to concrete with high performance ,strength and fluidity. When make C50 concrete,it should choose the
suitable material according to relative technology rule and confirm the suitable mixing technology base on enough
test data. To make sure the fluidity of concrete can meet with the requirements of engineering, the strength of
concrete should have surplus .
◆ This product can be added into concrete together with water which is used in mixing. but it will get better
performance if mix it with water firstly.
