Zinkbolt is specially developed for anchoring hot galvanized bolts. Zinkbolt can be used for grouting fully cast-in bolts, not prestressed or combination bolts. Zinkbolt is a thixotropic, cement based, non-shrinking dry mortar which expands 1 – 3% before setting. The mortar requires only the addition of water. The expanding component makes the mixture expand 1 – 3% while fresh: this ensures that Zinkbolt completely fills the cavity where it is placed, and fits closely around the bolts. The mixture must be placed within 40 minutes of mixing in order to ensure maximum expansion. The consumption of the product is approximately 1,6 kg of powder for 1m2.
