Concrete Super Plasticizer

Concrete Super Plasticizer – PN33-N

Description:

PN33-N is a neutral concrete super plasticizer based on naphthalene sulfonate, designed to enhance concrete workability while significantly reducing water content. This high-range water reducer improves the mechanical strength of concrete and prevents bleeding and segregation without affecting the cement hydration process.

Mechanism of Action

Upon mixing with water and cement, PN33-N molecules form a charged film around cement particles, causing them to repel each other. This dispersion enhances concrete fluidity while maintaining a low water-to-cement ratio, improving early and final strength.

Key Properties

• Compatible with all Portland cement types.
• Increases workability and slump without extra water.
• Reduces water-to-cement ratio by 10-15%.
• Enhances pumpability and reduces pump wear.
• Improves concrete durability and cohesion.
• Increases compressive and flexural strength at all ages.
• Prevents shrinkage and creep.
• Minimizes vibration requirements.

Applications

• High-performance concrete production.
• Structural concrete (bridges, precast elements).
• Mass concrete pours.
• Pumped concrete applications.
• Pre-stressed and post-tensioned concrete.
• Cement grout and injection applications.
• Dense reinforcement concrete sections.
