SRA-101 Shrink Reducing Admixture

Domcrete SRA 101 is a premium shrinkage reducing admixture (SRA) designed for use in GFRC, ECC, and conventional concrete mixes. Formulated to reduce plastic and drying shrinkage, SRA 101 helps prevent cracking, curling, and surface defects, ensuring stronger, more durable concrete elements.

When added to your mix, SRA 101 improves dimensional stability without negatively affecting workability, strength, or finish quality. It is fully compatible with Domcrete Alpha Premix systems, fibres, and other admixtures, making it ideal for high-performance architectural applications, concrete benchtops, wall panels, and decorative elements.

Key Features:

• Reduces plastic and drying shrinkage

• Enhances dimensional stability and crack resistance

• Compatible with GFRC, ECC, and conventional concrete

• Maintains workability and strength of the mix

• Safe and easy to use in premixed or on-site formulations

SRA-101 typically reduces ultimate shrinkage values by up to 50% depending on the cement type used.

Typical dosages in standard mix designs are between 283grm-850grm (10-30oz) per cwt of cement.
