R-Grout Aid (GA-213)

GA213 R-Grout Aid is a powdered admixture for concrete used 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
  • Non shrinking
  • Expanding properties ensure better cell wall adhesion
  • Better pumping properties
  • Less segregation
  • Will not corrode reinforcing steel

Uses:

  • Masonry grouts
  • Concrete block grouting
  • Clay brick grouting
