KingAnchor

HIGH PERFORMANCE AND NON-SHRINK GROUT MATERIAL FOR ANCHORING APPLICATIONS

KingAnchor is a prepackaged, non-shrink, non-metallic, and cementitious grout material for anchoring applications with a unique two-stage shrinkage compensating mechanism. With a special blend of shrinkage-reducing and plasticizing/water-reducing agents, this product compensates for shrinkage in both the plastic and hardened states.

  • Excellent pumpability
  • Excellent cohesion and plastic stability
  • Thixotropic properties reduce material loss in fractured ground
  • Does not contain aluminum powder nor any components which generate hydrogen gas, carbon dioxide, or oxygen.
  • Enhanced with un-densified silica fume for low permeability.
  • Non-metallic, will not stain or rust.
  • Bleed resistant, even at high flow.
  • Non-shrink
  • Low heat build-up.
  • Non-corrosive.

Application steps

SURFACE PREPARATION

  • Remove all deteriorated concrete, dirt, oil, grease, and other bond-inhibiting materials from the area to be repaired leaving a clean surface.
  • To ensure optimum repair results, the effectiveness of decontamination and preparation should be assessed by a pull-off test.
  • Substrate should be Saturated Surface Dry (SSD) with clean water prior to application. No standing water should remain during application.
  • Ensure any forms will retain grout without leakage.

MIXING

  • Start by using 12.75 pints (6 L) of water at approximately 70°F (If higher, use cold water; if colder, use warm water.) per 55 lb bag (25 kg) in a clean and appropriate mixing vessel.
  • Add bag of material to mixing vessel. Mix for minimum of 3 minutes after the addition of the last bag or until a homogeneous mix is achieved.
  • Continue to agitate material in the holding hopper to achieve best flow.
  • Only add additional water as needed up to a total maximum of 13.75 pints (6.5 L) (DO NOT EXCEED) per 55 lb bag (25 kg) in order to achieve the flow specified on the Product Data Sheet (PDS).
 
  • At higher temperatures and/or water amounts near upper range of maximum 13.75 pints (6.5 L), the grout will be less thixotropic. Therefore, it may be more appropriate to measure the flow using the standard flow cone test (ASTM C-939).
  • Alternatively, for quantities less than a 55 lb bag (25 kg), mechanically mix with high-speed drill (2,500 rpm) for a minimum of 6 minutes.
  • Method of mixing may significantly affect the material properties, particularly flow.
  • Project specific testing by the engineer is recommended to ensure that the mixing and placement methods result in the specified requirements

APPLICATION

  • Make sure all forming, mixing, placing, and clean-up materials are on hand.
  • A preliminary trial should be completed on-site and inspected by the engineer to ensure that the placement means and methods yield the specified results

  

OPTIMUM PERFORMANCE

  

  • Product should not be applied when ambient and substrate are below 40 °F (5 °C) or above 100 °F (38 °C).
  • Product should not be applied if product temperature is below 65 °F (18 °C) or above 75 °F (24 °C), or if product is contaminated with moisture.
  • Use of a colloidal mixer similar to ChemGrout© CG-600 series or other type of high shear mixer at approximately 1,800 rpm.
