Abstract

Staklo je jedan od najvažnijih materijala u industriji i svakodnevnom životu zbog svojih
izuzetnih svojstava i široke primjene. Transparentnost stakla omogućava prolazak svjetlosti,
čineći prostor svijetlim i prostranim. Osim toga, staklo je kemijski inertno, što znači da ne
reagira s mnogim tvarima, čineći ga idealnim za upotrebu u kemijskim posudama i
laboratorijskoj opremi. Njegova izdržljivost i lakoća čišćenja čine ga također popularnim
izborom za prozore, boce, posuđe, vaze i optička vlakna.
Recikliranje stakla ima ključnu ulogu u očuvanju prirodnih resursa i zaštiti okoliša. Staklo se
može reciklirati bez gubitka kvalitete ili svojstava, što omogućuje njegovu ponovnu upotrebu.
Ovaj proces smanjuje potrebu za eksploatacijom novih sirovina i smanjuje količinu otpada koja
završava na odlagalištima.
Pored tradicionalnog stakla, postoji i poseban oblik poznat kao pjenasto staklo. Pjenasto staklo
karakterizira prisutnost zatvorenih pora koje ga čine iznimno laganim i izolacijskim. Proces
proizvodnje pjenastog stakla uključuje dodavanje tvari koje stvaraju mjehuriće zraka tijekom
taljenja i oblikovanja stakla. Ovo staklo ima izvrsna toplinska i zvučna izolacijska svojstva, što
ga čini idealnim za primjenu u građevinskoj industriji. Koristi se za izolaciju zidova, stropova
i podova, pružajući energetsku učinkovitost i smanjenje buke.
U eksperimentalnom dijelu ispitana su dva staklena uzorka izrađena od recikliranog stakla.
Granulati recikliranoga bezbojnog stakla međusobno su povezani natrijevim silikatom i
dodacima. Provedeno je tlačno ispitivanje te su doneseni zaključci o kvaliteti staklenih uzoraka
i mogućoj primjeni materijala izrade u fasadnim blokovima.

Abstract (english)

Glass is one of the most important materials in industry and everyday life due to its
exceptional properties and wide range of applications. The transparency of glass allows the
passage of light, creating bright and spacious environments. Additionally, glass is chemically
inert, meaning it does not react with many substances, making it an ideal choice for chemical
containers and laboratory equipment. Its durability and ease of cleaning also make it a popular
option for windows, bottles, dishes, vases, and optical fibers.
Glass recycling plays a crucial role in preserving natural resources and protecting the
environment. Glass can be recycled without losing its quality or properties, enabling its reuse.
This process reduces the need for extracting new raw materials and minimizes the amount of
waste ending up in landfills.
In addition to traditional glass, there is a special type known as foam glass. Foam glass is
characterized by its closed-cell structure, making it extremely lightweight and insulating. The
production process involves adding substances that create air bubbles during the melting and
shaping of glass. This type of glass exhibits excellent thermal and sound insulation properties,
making it ideal for applications in the construction industry. It is used for insulating walls,
ceilings, and floors, providing energy efficiency and noise reduction. It is also utilized in the
automotive industry to improve sound insulation and enhance vehicle energy efficiency.
In an experimental study, two glass samples made from recycled glass were examined.
Granules of colorless recycled glass were bonded together using sodium silicate and additives.
Compressive testing was conducted to evaluate the quality of the glass samples and the
potential application of the material in facade blocks.
