Abstract

A two-component mortar composition for securing stays and for rock stabilization in mining having an unsaturated polyester in one component and a hardener material in the other. The composition comprises a total of 15 to 35 weight percent of unsaturated polyester, 9 to 25 weight percent of reactive diluent, 44 to 66 weight percent of filler, 0.5 to 4 weight percent of thixotropic agent, and 1 to 6 weight percent of a hardener which is a free radical curing catalyst. The composition exhibits desired strength levels and also exhibits the desired securing properties for mortar compositions as well as ease of handling.
