CONCRETE BLOCK GROUT
MAIN FEATURES
■ Very fluid
■ Without segregation and excessive bleeding
Grouts are very fluid products. The high fluidity allows the grout to penetrate the cavities of the concrete blocks throughout the building, despite the presence of rebar and/or other elements resulting from the architectural details. To this end, mortar should never be used to replace grout.
Nowadays, grouts are of the expansive type. During the fluid phase, the grout will expand, which will compensate for the generally observed shrinkage occurring with the use of Portland Cement products, and will also guarantee a superior adhesion.
The resistance of the selected grout will depends on the type of use. Following this rule, Sika recommends for users to always consult with a structural Engineer before selecting a grout resistance.
TIP
Since hydrated lime develops compressive strength once in contact with air, the use of non-hydraulic lime in the grout composition is not recommended.
Recommendations
TYPE OF GROUT RECOMMENDED:
■ Medium compressive strength: King® E-20
■ High compressive strength: King® E-30
