Polycarboxylate Based Superplasticizer for Slump Retention of Concrete Admixture

Product Description

Product Overview
 

PCE superplasticizer represents the latest generation of superplasticizers utilized for concrete both at home and abroad. It is developed on the basis of the molecular design and adsorption capacity of polycarboxylate. Through research and development, we have successfully produced a water - reducing and slump - retaining type of polycarboxylate superplasticizer for concrete. By optimizing the initiating system and reaction conditions, we've achieved high adaptability.

 

When compared with PNS and other superplasticizers, PCE superplasticizer boasts numerous characteristic advantages in terms of technology and performance as follows:

 

(1) It requires a low dosage but offers a high water - reducing rate.
(2) It can maintain a good slump retention of concrete.
(3) It has excellent compatibility with cement.
(4) It causes less shrinkage of concrete, thus ensuring the stability of volume and durability.
(5) Its production and usage are environmentally friendly.

Key Features
High water - reducing rate: The water - reducing rate can reach 25% - 40%, significantly reducing the water - binder ratio of concrete.
Excellent slump retention: It can maintain the slump of concrete stably and delay the setting time
Low shrinkage: It reduces the risk of shrinkage cracking during the hardening process of concrete.
Strong adaptability: It has good compatibility with different cement types and mineral admixtures
Environmental friendliness: It has a low chloride ion content and meets the standards of green building materials
 

Application Scope of PCE

Building engineering: It is widely used in precast and cast - in - situ concrete, reinforced concrete, and prestressed concrete for industrial and civil buildings. It helps enhance the strength of concrete and the workability of construction, meeting the requirements of different building structures.

Transportation infrastructure: It is applicable to the construction of projects such as roads, bridges, port terminals, and airports. In road construction, it improves the performance of concrete and increases its durability; in large - scale projects like bridges and ports, it ensures the structural stability.

Special projects: It is especially suitable for projects such as nuclear power engineering that have high requirements for maintaining the slump of concrete and long construction periods. It maintains the good working performance of concrete and ensures the project quality.

Building materials products: It can be used in the production of high - strength mortar, gypsum products, self - leveling floors, caulking compounds, grouting materials, etc., improving product quality and construction efficiency.
    

Method of use

Based on the performance requirements of concrete, add PCE at a dosage of 0.8%-2.0% by mass of the cementitious materials (the optimal dosage should be determined through trial mixing). Pre-dissolve it in water or add it directly to the concrete mixing equipment, and mix uniformly with cementitious materials, aggregates, etc. simultaneously. During construction, pay attention to the compatibility with cement and admixtures, and control the mixing time.

Packaging and shipping
 

Packaging: Typically stored in sealed plastic drums, metal tanks, or bulk containers (e.g., 200 kg drums or ISO tank containers) to prevent moisture, contamination, and leakage.

Shipping: Transported as non-hazardous chemicals by road, rail, or sea. Avoid prolonged exposure to extreme temperatures (store at 5-35°C) and ensure containers are securely sealed to prevent spillage during transit. Label packages with product name, specifications, manufacturer information, and handling precautions (e.g., "Keep Dry," "Avoid Sunlight").
