Grout Aid:
GA213 R-Grout Aid is a powdered admixture for concrete uses in grouting of concrete block and clay brick. GA213 improves the placing properties and the bond between the grout and masonry unit. Concrete with R-Grout Aid has better pumping properties, higher compression strengths, increased yields, better flow, less segregation and better sheer bond strength. R-Grout Aid will produce slight retardation, expansion, and water reduction characteristics. Contains no corrosive chemicals. Will not compromise reinforcing steel. R-Grout Aid is approved by the California Department of State Architects (DSA) for use on state schools, hospitals, and other state projects.
Advantages:
Higher bond and compressive strength
Better pumping properties
Less segregation
Will not corrode reinforcing steel
