Use of Recycled Superabsorbent Polymers (SAPs) to Create Multifunctional Concrete

Description:

This technology integrates superabsorbent polymers (SAPs) into Portland cement concrete to enhance its material properties and serviceability. SAPs, with their ability to absorb water or aqueous solutions up to 500 times their own mass, introduce significant improvements in concrete, including reduced shrinkage cracking, enhanced mechanical and rheological properties, and increased durability against environmental stressors.

Key Advantages:

• Significantly reduces shrinkage cracking.
• Improves mechanical properties of concrete.
• Modifies rheological properties for better workability.
• Enables self-sealing and self-healing capabilities.
• Controls thermal cracking effectively.
• Enhances freeze-thaw resistance of concrete.
• Offers a more effective and practical solution than traditional curing methods.

Problems Solved:

• Shrinkage cracking in concrete structures.
• Poor mechanical properties leading to early deterioration.
• Difficulty in controlling concrete workability.
• Lack of self-healing properties in concrete for longevity.
• Thermal and freeze-thaw induced damage.
• Inefficiencies and limitations of traditional concrete curing techniques

Market Applications:

• Construction of buildings and infrastructure with enhanced durability.
• Repair and maintenance of concrete structures requiring minimal intervention.
• Specialized applications in environments prone to thermal and freeze-thaw cycles.
• Development of self-healing concrete for future smart cities.
