Abstract (en)

[origin: WO9841408A1] A sand material mixture comprises on the one hand sand or a sand-like material of a certain grain size and on the other a binding agent which contains beeswax, a material similar to beeswax, or a material mixture similar to beeswax, or a mixture of such materials, and which is solid at room temperature but yet exhibits a tackiness matching the tackiness of beeswax. The components of the sand material mixture are mixed in such a manner that the grains (10, 11) of sand or sand-like material receive a coating (12) of the binding agent. The sand material mixture has proved useful as a material for toys, as a pedagogic material, and as a material for constructing imitated architectural landscape designs, landscape designs in museums or in aquariums.
