Abstract:
    A coarse/fine particulate inert solid filler component, e.g., limestone and/or sand, is used in a hardenable resin composition adapted for use in making set products, e.g., a hardened grout for anchoring a reinforcing member in a hole. About from 5 to 50 percent by weight of the filler is a coarse filler component comprised of particles in a size range whose minimum is about 1 mm, or a size range which is from 30 to 105 percent of the thickness of the annular layer of hardened grout formed around a reinforcing member. The thus-filled resin composition is readily miscible and flowable. Rock bolt grouting products containing this resin composition require less bolt spinning and afford improved anchorage strength, even when used to point anchor mechanical expansion shells.
