Advantages

87% lower autogenous shrinkage

Amphiphilic groups reduce surface tension and capillary stress in pore solution, directly suppressing autogenous shrinkage.

51.8% lower cracking index

Reduced shrinkage and harmful pores jointly lower cracking risk, improving long-term durability.

Water reduction retained

Molecular design retains the dispersing ability of polycarboxylate superplasticizers without changing dosage or process.

27.2% fewer harmful pores

Optimized pore structure reduces harmful pores, further enhancing mechanical properties and durability.

Applications

• High-performance concrete：Reduces autogenous shrinkage and cracking risk, ensuring volume stability of high-strength concrete.
• Mass concrete：Lowers thermal and autogenous shrinkage, reducing temperature cracking in mass concrete.
• Self-compacting concrete：Maintains high flowability while reducing shrinkage, preventing cracking in self-compacting concrete.
• Cement-based composites：Optimizes pore structure and reduces shrinkage, improving durability of cement-based composites.
