Anchoring Grouts: Pumpable, Bulk Packaged
CarboThix 2 is an instantly thickening fast curing dual component silicate resin for high strength bonding of solid bolts and cable anchors. CarboThix 2 was developed to improve the productivity of ground support installations in underground mining and tunnelling applications. Using the pumpable resin enables load to be taken up in minutes rather than the typical 24 hours from cementitious grouted systems.
Typical applications of CarboThix 2 include sealing of injection bolts, steel or GFRP rods, and sealing of roof bolts. During application, the two components are intimately mixed and achieve a grease-like viscosity (the so called Thix effect) so that the grout stops flowing and cures to form a tough elastic and non-porous resin that will not mix with water or be diluted in wet holes. CarboThix 2 is resistant to dilute acids and alkalis as well as fats. As the system is under pump pressure, some grout is pushed into minor cracks and fissures around the anchor hole, ensuring full encapsulation of the anchor.
As the two resin components are mixed at a set volume, consistent mixing of the grout is guaranteed, an advantage over cementitious grouts. This delivers a reliable quality of grout and anchoring performance. Operator safety and handling issues are also improved over cementitious grouting systems. As a pumpable resin system, CarboThix 2 can be handled over long distances (up to 500 m) improving operational flexibility.
