Quartz is found in sedimentary, metamorphic, and igneous rocks. During sand formation in the fluvial environment, quartz grains are highly resistant to weathering and mechanical wear, and can be transported a long way without changes to size and form. Therefore, quartz is the main constituent of most natural sands. Quartz and quartz sand are ubiquitous raw materials used in a wide range of products in civil engineering due to their chemical inertia and high temperature resistance. An example of a quartz sand deposit and processing plant in Slovenia is presented as a practical case study on quartz sand application. The described applications using quartz sand are the best available technologies in sanitary and hydraulic engineering to be used for a move towards a circular economy, smart houses, and smart citiesV prispevku je podan pregled pridobivanja in uporabe kremenovega peska kot posebej zanimive vrste peska za gradbeništvo od nastanka nahajališč, preko metod rudarjenja in predelave do končne uporabe v gradbeništvu s poudarkom na uporabi pri filtraciji vode. Kremen je prisoten v sedimentnih, metamorfnih in magmatskih kamninah. Med tvorbo peska v fluvialnem okolju so kremenova zrna zelo odporna na vremenske vplive in mehansko obrabo, njihova velikost in oblika ostajata nespremenjeni tudi po premeščanju na daljše razdalje. Zato je kremen glavna sestavina večine naravnih peskov. Kremen in kremenov pesek sta zaradi svoje kemijske inertnosti in visokotemperaturne odpornosti vseprisotna surovina, ki se uporablja v širokem naboru gradbenih izdelkov. Naveden je primer nahajališča in obrata za predelavo kremenovega peska v Sloveniji kot konkretni primer njegove uporabe. Opisane uporabe kremenovega peska predstavljajo najboljše razpoložljive tehnologije v hidrotehniki in komunali, ki jih moramo uporabiti za prehod v krožno gospodarstvo, pametne hiše in pametna mestaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za gradbeništvo in geodezijo
