A set plaster- and resin-containing composition is made by mixing together an aqueous solution of a settable resin, for example an aminoplast resin such as a urea-formaldehyde resin, a calcium sulphate plaster which sets on contact with water, and a resin hardener. A resin modifier such as furfuryl alcohol or glycerol may advantageously be mixed into the composition, which may also include further additives such as dispersing agents, inert fillers, reinforcing fibres, thickeners, surfactants, foaming agents and plaster hardeners. The composition may advantageously be made from a kit comprising a resin component and a plaster component, the plaster component including the resin hardener. The composition may be used for strata consolidation in mining, as a roof bolt grouting composition in mining, for modelling statuettes, for the manufacture of prefabricated building panels, and other uses. |
