DESCRIPCI\u00d3<\/p>\n

\u00c9s un minaral format per sulfat de calci dihidratat (CaSO4\u00b72H2O), que cristal\u00b7litza en el sistema monocl\u00ednic. \u00c9s un material petri que transformat industrialment s’anomena sulfat de calci hemihidratat (CaSO4\u00b7\u00bdH2O). Tamb\u00e9 se’l coneix com a “guix cuit”. Les seves propietats, es van descobrir fa m\u00e9s de cinc mil anys a lantic Eguipte.En estat natural, el guix cont\u00e9 un 79,07% de sulfat de calci anh\u00eddrid i un 20,93% d’aigua i quan es troba en grans quantitats \u00e9s considerat tamb\u00e9 una roca sediment\u00e0ria. \u00c9s incolor o blanquin\u00f3s, per\u00f2 a causa de les impureses tamb\u00e9 es pot presentar amb tons de gris, marr\u00f3, groc, vermell, etc. Acostuma a ser transparent, amb llu\u00efssor v\u00edtria o setinada, s\u2019exfolia en escates fines i flexibles per\u00f2 no pas el\u00e0stiques, \u00e9s tou, pot ser ratllat per l\u2019ungla.

\u00daS
\nA l’escalfar-se, el guix perd aigua per\u00f2 la recupera r\u00e0pidament i endurint-se, aprofitant aquesta propietat s\u2019utilitza per a m\u00faltiples aplicacions, moltes lligades al sector de la construcci\u00f3. Segons la temperatura a la qual es produeix el proc\u00e9s de deshidrataci\u00f3 el guix s\u2019adorm (\u00e9s a dir s\u2019endureix) m\u00e9s o menys r\u00e0pidament. La ind\u00fastria de la construcci\u00f3 n\u2019\u00e9s la principal consumidora.
\nLLOC D\u2019ORIGEN
\nEl guix es va originar fa 200 milions d’anys com a resultat de dip\u00f2sits marins quan part del que ara s\u00f3n els nostres continents eren immenses extensions oce\u00e0niques. Durant aquest per\u00edode alguns mars es van assecar deixant llits de guix que es van recobrir per ser descoberts posteriorment per l’home.<\/p>\n
