PCE superplasticizer 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.
Due to most of PCE superplasticizer is liquid and procedure of PCE powder is complex and dangerous, PCE superplasticizer is mostly sold in liquid in market.
Recently, with the technology and procedure improved, PCE powder is common in market. the powder will be more convenient for client in transport and use. So the powder is becoming the trend of this product.

It makes cement good dispersibility and fluidity in low dosage.
When dosage is from 0.12% to 0.22%, the cement paste fluidity grows obviously.
There is no loss of fluidity within 1 hour in cement paste.
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.
4.It has antifreezing performance when temperature is above -5ºC. So it can be used in antifreezing concrete.

It is based on molecular designs and adsorption capacity of polycarboxylate,we do R&D and successfully produce water reducing and retention type polycarboxylate superplasticizer for concrete.With initiating systerm and reaction conditions,we achieve high adaptability.
Main function: wide adapability of kinds of cements,gravels and sands. water reducing ratio and better retention,ability of solving slit content of sand and gravel.With it's stable performance,it's widely used in all kinds of concrete projects and cement product, that is well received at home and abroad.
Polycarboxylate Superplasticzier we produce types as below:
Water reducing and slump retention type:
JH-03 Water Reducing & Retention Type Standard type according ASTM C494
JH-09 High Water Reducing & Mid-retention Viscosity adjusted Type.
JH15 water reducing ratio is higher than JH03,concrete performance is better than JH03,suitable for high strength concrete.
JH600 similar water reducing ratio is with JH03,concrete performance is better than JH03 according to local raw materials of concrete.
High slump retention type:
JH06 standard basic type,mix with JH03 and JH09 if concrete's slump retention is not satisfied.
