ORGANIC GROUTING SYSTEM FOR ANCHORING A BOLT IN A HOLE, AND CARTRIDGE CONTAINING SUCH COMPOSITION |
摘要 |
An improved rock-bolt grouting composition based on a cross-linkable unsaturated polymerizable polyester resin formulation in one component and a peroxide catalyst in a separate component, contains diffused water, preferably in the catalyst component, in an amount sufficient to provide a weight ratio of resin formulation to water no greater than about 6.0, and a particulate solid filler in both components in an amount sufficient to provide a weight ratio of filler to resin formulation of at least about 3.0. The filled, water-extended composition generally expands during the cross-linking of the polymer, and greater interfacial strength in smooth-walled boreholes has been found. Compositions in which water is the catalyst vehicle are preferred because their shelf life is better than those containing an oil-based catalyst. |
