Subject aims expressed by acquired skills and competences
The aim is to inform students with principal steps of silicate construction materials production technology, i.e. especially binders, ceramics, melting rocks, including thermal and noise insulations, glass and alkali-activated materials. (geopolymers). The stress is put on the phase and micro structural changes during production process that can influence material properties.

Summary
Předmět navazuje na předchozí předměty „Stavební hmoty“, „Chemie a stavební hmoty“. Podává přehled o současných technologiích výroby základních silikátových stavebních materiálů – především pojiv, skla, tavených hornin a keramiky. Zároveň seznamuje studenty se základními silikátovými (křemičitanovými) minerály, které mají důležité využití v technice a zejména ve výrobě stavebních hmot. Pozornost je věnována rovněž procesům, probíhajícím v technologii silikátů (difúze, nukleace, slinování). Ve cvičeních se studenti seznámí zejména s výpočty složení surovinových směsí v technologii cementu a stavební keramiky a s některými zkušebními metodami silikátových výrobků. Teoretická výuka je doplněna praktickými exkurzemi do provozů silikátových technologií (výroba cementu, výroba stavební keramiky včetně střešní krytiny, výroba žárovzdorných hmot, výroba tepelných a zvukových izolací na bázi strusko-čedičové vlny, výroba granulované vysokopecní strusky, výroba stavebního skla apod.).
