Shrinkage Reducing Admixture (SRA) for Sale – High-Performance Concrete Additive
Looking to buy Shrinkage Reducing Admixture (SRA) at competitive bulk pricing? Our SRA for sale is a high-performance concrete additive designed to minimize drying shrinkage, reduce cracking, and improve long-term durability.
Formulated using advanced alkylene glycol, polyether, and alcohol-based chemistries, our SRA delivers consistent performance across a wide range of concrete applications.
What is Shrinkage Reducing Admixture (SRA)?
Shrinkage Reducing Admixture (SRA) is a chemical additive used in concrete to:
- Reduce drying shrinkage
- Minimize crack formation
- Improve dimensional stability
👉 It works by reducing surface tension in pore water, lowering capillary stress during drying.
Available Material Grades
We offer multiple SRA formulations and raw material bases to suit different applications:
Standard & Advanced Grades
- Neopentyl Glycol (NOG)-Based SRA
- Standard SRA (Liquid)
- High-Concentration SRA
Solvent-Based Options
- Ethanol / Isopropanol (IPA) Based SRA
- Hexylene Glycol-Based SRA
Polyether-Based Options
- Polypropylene Glycol (PPG)-Based SRA
- PEG-PPG Block Copolymers
- Allyl Polyether-Based SRA
Chemical Base Variants
Our SRAs are formulated using:
- Alkylene Glycol-Based SRAs → Cost-effective and widely used
- Polyether-Based SRAs → Enhanced durability and performance
- Alcohol-Based SRAs → Fast-acting and efficient
Key Benefits of SRA
- Reduces drying shrinkage by 20–50%
