Product Description: GA213 R-Grout Aid is a powder admixture for concrete used in grouting of concrete block and clay brick. GA213 improves the placing properties and the bond between grout and masonry unit. Concrete with R-Grout Aid has a better pumping properties, higher compressive strengths, increased yields, better flow, less segregation and two times the sheer bond strength. R-Grout Aid GA213 will have slight retardation, expansion and water reduction. It contains no chlorides or other chemicals, which contribute to corrosion of reinforcing steel. Uses: Grouting of concrete block or clay brick. Advantages: Higher bond and comprehensive strength Improved pumping properties Less segregation Easier Compaction Cost effective

Packaging: GA213 R-Grout Aid is available in 13 lb. Moisture resistant containers. Shelf life is 2 years in original unopened containers.

Technical Data: Grout mix design should be a minimum of 6 sacks of cement. 60-70% washed concrete sand and 30-40% 3/8 in. aggressive per cubic yard. Fine grout mixes are recommended at a maximum of 3:1 sand to cement ratio. Grout ingredients shall conform to U.B.C. and A.S.T.M. standards. The ready mix supplier must be notified of the addition of Grout Aid to avoid overdosing the concrete.

Addition Rate: GA213 is added at the rate 1/7% of the total cement content. R-Grout Aid is added to the ready mix truck at the jobsite. It may also be pre-blended with dry blend concrete and grout mixes. Grout should be ordered from the ready mix plant at a 5-6 in. slump. Extended slump life is approximately 30-40 minutes. Batches should be placed within 1 hour so that as much of the expansion action occurs after the grout is placed. Add slowly for proper mixing.

Limitations:

• Grout must be used within 1 ½ hour
• Consult an R-Crete Representative prior to use in applications other that grout for masonry units
• Ready Mix Supplier must be notified of the jobsite addition to avoid overdosing

Caution: R-Grout Aid contains aluminum materials. Prolonged exposure to dust may cause delayed lung disease. Freshly mixed materials may cause skin irritation. Avoid direct contact where possible and wash exposed skin areas promptly. If any material gets in the eyes, rinse immediately and repeatedly with water and get prompt medical attention.
