2. High slump retention performance: Normally carboxylic groups is damaged of ordinary polycarboxylate superplasticizer by the high temperature during dry spray process, this product takes the special process so protect the carboxylic groups and achieve the excellent slump retention ability.
3. Excellent solubility and fast solvability: Due to uniform particles, the specific area is larger, so the product is dissolved quickly in the water then no impurity after dissolving
DOSAGE
0.2~0.3% of the aggregate material, it is instead of liquid polycarboxylate superplasticizer after dissolving the dosage after dissolving reference to the actual solid content of dissolving liquid.

Polycarboxylate superplasticizer (PCE) is a high-performance, water-reducing admixture for modern concrete applications. Utilizing advanced polymer technology, it offers superior slump retention and strength enhancement compared to traditional superplasticizers.
Performance Characteristics
--Water Reduction: 25-40% (vs. 15-25% for naphthalene-based)
--Slump Retention: Maintains workability for 2-4 hours
--Early Strength: 50-80% higher at 1 day vs. conventional SPs
--Compatibility: Works with all cement types (OPC, SCC, slag cement)
--Low Dosage: 0.1-0.3% by cement weight (1/3 of sulfonated melamine types)
Applications
1. Ready-Mix Concrete

Ideal for transit-mixed concrete requiring long workability

Reduces segregation in high-slump mixes (200-250mm)

2. Precast/Prestressed Concrete

Enables early demolding (12-16 hour cycle time)

Improves surface finish quality

3. Self-Consolidating Concrete (SCC)

Achieves 600-800mm flow without vibration

Maintains stability at low water/cement ratios (0.28-0.32)

4. High-Performance Concrete

Enables 100+ MPa compressive strength

Reduces autogenous shrinkage by 30-50%

PCE superplasticizer is the newest generation superplasticizer for concrete projects in domestic and abroad. Comparing with FDN 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.

PCE Polycarboxylate superplasticizer is the newest generation superplasticizer used for concrete in domestic and abroad.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.
