SikaGrout Aid Plus is an aluminum-free, multi-functional grout admixture engineered to optimize portland cement grout performance in critical structural applications. This balanced blend combines fluidizing, water-reducing, shrinkage compensating, and anti-bleed properties to deliver consistently high-quality grout mixes on job sites. Designed specifically for horizontal and vertical prestressed tendon applications and pre-packed aggregate cavities, this gray powder additive transforms standard cement grouts into precision-grade materials that meet stringent construction requirements.
With a targeted water-to-powder ratio of 0.28-0.30 and a 60-minute working time, SikaGrout Aid Plus enables contractors to achieve superior grout performance without compromising workability or installation schedules. The formulation’s anti-bleed characteristics prevent water separation while its shrinkage compensation properties maintain structural integrity over time. This specialized admixture requires high-speed mixing at 2,000-2,500 rpm for optimal performance, ensuring uniform distribution and maximum effectiveness in demanding construction environments.

Frequently Asked Questions
What is the recommended mixing ratio for SikaGrout Aid Plus?
Use 3-4% of SikaGrout Aid Plus per 100 pounds of cementitious material with a water-to-powder ratio of 0.28-0.30.
How long do I have to place the grout after mixing?
SikaGrout Aid Plus must be placed within 60 minutes of mixing for optimal performance.
What mixing equipment should I use?
Use a high-speed drill operating at 2,000-2,500 rpm or a colloidal mixer like ChemGrout CG 600 for best results.
Can this replace Class C pre-packaged grout?
No, SikaGrout Aid Plus is an admixture for enhancing job site grout mixes and is not a substitute for Class C pre-packaged grout.
What is the proper mixing sequence?
Add ingredients in this order: water, approximately 50% cement, SikaGrout Aid Plus, then remaining cement.
How should the product be stored?
Store in a dry location at 40-95°F (4-35°C), protected from moisture. Shelf life is 6 months in original unopened packaging.
