Abstract

Przedmiotem zgłoszenia jest sztuczny piaskowiec uzyskany w wyniku scalania piasków, a zwłaszcza piasków rzecznych, kopanych i płukanych charakteryzujący się tym, że zawiera piasek w ilości 80 - 85% wagowych, krzemianu sodu w ilości 7 - 15% wag. w stosunku do scalanej mieszaniny i jego utwardzacz w ilości 1 - 14% wag. w stosunku ilości krzemianu sodu, oraz nanokrzemionkę w ilości 2 - 4% wag. w stosunku do scalanej mieszaniny, przy czym sztuczny piaskowiec ma masę właściwą 1,45 - 1,75 kg/dm3, nasiąkliwość < 6,4%, ścieralność 0,1 - 0,4 cm, mrozoodporność wynosi 44 cykle, ognioodporność < 1150°C.The subject of the application is artificial sandstone obtained as a result of merging sands, in particular river, dug and washed sands, characterized in that it contains sand in the amount of 80 - 85% by weight, sodium silicate in the amount of 7 - 15% by weight. 1 - 14% by weight relative to the mixture being mixed and its hardener in the ratio of sodium silicate, and nanosilica in the amount of 2-4 wt. relative to the merged mixture, the artificial sandstone has a specific mass of 1.45 - 1.75 kg / dm3, water absorption <6.4%, abrasion 0.1 - 0.4 cm, frost resistance is 44 cycles, fire resistance <1150 ° C.
