“…The smooth and plane surface of large recycled glass particles can significantly weaken the bond between the cement paste and the glass particles [27,67]. Mechanical properties, in general, decrease in proportion to an increase in waste glass aggregates/powder at earlier ages [23,32,33,38,54,56,59,68]. A reduction in modulus of elasticity with increased waste glass has been observed [54], although finely ground waste glass showed an opposite effect on the mechanical properties [24,58] and reintroduced avenues for the reuse of the ground waste glass aggregate as a fine aggregate for the manufacturing of mortars and concrete, in particular when high performance was required.…”

Waste glass is an endless issue for the majority of the countries in the world with a linear economy of usage of materials. Demolition waste is counted as part of total construction and demolition waste (CDW). Even today, there are some statistical problems with the quantification of demolition waste and dividing it from total CDW, since most countries do not provide such a division of waste types. The current review shows possible ways of utilizing waste glass in some useful products in the construction industry. It is elaborated using PRISMA@ methodology with bibliometric and qualitative methods to provide a systematical overview of the publications in the period from 2000 to 2023. The bibliometric search was handled with the application RStudio© using sources in the biggest database, Scopus. Most of the published research items are mainly focused on using waste glass in concrete applications. However, there are seven possible areas of waste glass application in the construction industry: concrete products, gypsum–cement composites, asphalt or concrete pavement, geopolymer mortars, foamed glass ceramics, glass ceramics, and soil foundation strengthening/stabilization. In its turn, the circular economy should be applied since it provides a prolonged turnaround of materials throughout their life cycle.

“…The second option would be using finely ground waste glass as a substitute for a part of cement while making concrete and mortar. The previous research pointed to the fact that milling the glass with amorphous silicon of high content into a fine dust (particles smaller than 100 µm in size) initiates its pozzolanic reactivity, that being the basic precondition for using it as a supplementary cementitious material [5][6][7][8][9][10]. Testing the durability of concrete with added CRT glass, be it used as a filler or as a replacement of a part of cement, is very topical.…”

One of the essential requirements in modern civil engineering is a sustainable building, with the aim of reducing the harmful impact on the environment. Since the early XXI century, usage of recycled materials has been insisted on, which could, at least partly, substitute traditionally used materials. Although there is no serial manufacturing of TV sets with cathode ray tubes anymore, piles of cathode ray tube glass (CRT) at the waste disposal sites have still been on the increase. This experimental research was supposed to determine the potential for using subtly milled CRT glass as a supplementary cementitious material and to check the resistance of similar concretes to the sulphate action. Six testing concrete batches were made. The percentage of cement replacement percentage with CRT was: 5%, 10%, 15%, 20% and 35%, by mass. Durability assessment of concrete to sulphate action was done by visual estimation of concrete appearance as well as through testing the compressive strength variations of treated concrete specimens 3, 6, 12 and 36 months old. After soaking the specimens in a 5% solution of Na2SO4 for 36 months, concretes with 15% to 20% of replaced cement with finely ground CRT glass have simultaneously satisfactory compressive strength and resistance to sulfate attack. In this sense, this range of replacement of cement with finely ground CRT glass can be recommended for practical application.

“…Such use of waste glass would have both economic and environmental benefits considering that cement-producing industries emit almost 7% of the total amount of global CO 2 emissions. Previous research determined that grinding the glass with a high content of amorphous silicon into a fine dust (particles finer than 100 µm) activates its pozzolanic reactivity, which is the basic precondition for its use as a supplementary cementitious material [14][15][16][17][18][19][20][21][22]. Nassar et al [23] determined a considerable increase in the compressive strength of the concrete in relation to the reference concrete at the age of 56 days, which was ascribed to the pozzolanic activity of ground mixed-color milled waste glass and formation of a denser concrete microstructure.…”

Durability Properties of Concrete Supplemented with Recycled CRT Glass as Cementitious Material

This paper presents the testing of the durability of concrete where a part of cement was replaced with ground panel cathode ray tube glass (CRT) finer than 63 µm. The percentage of cement replaced with glass is 5%, 10%, 15%, 20%, and 35%, by mass. The highest percent share of mineral admixtures in CEM II (Portland-composiste cement) cement was chosen as the top limit of replacement of cement with glass. In terms of the concrete durability, the following tests are performed: freeze-thaw resistance, freeze-thaw resistance with de-icing salts-scaling, resistance to wear according to the Böhme test, sulfate attack resistance, and resistance to penetration of water under pressure. A compressive strength test is performed, and shrinkage of concrete is monitored. In order to determine the microstructure of concrete, SEM (Scanning Electron Microscopy) and EDS (Energy Dispersive X-ray Spectroscopy) analyses were performed. The obtained research results indicate that the replacement of a part of cement with finely ground CRT glass up to 15% by mass has a positive effect on the compressive strength of concrete in terms of its increase without compromising the durability of concrete. The results obtained by experimental testing unequivocally show that concrete mixtures made with partial replacement (up to 15%) of cement with finely ground CRT glass have the same freeze-thaw resistance, resistance to freeze/thaw with de-icing salt, resistance to wear by abrasion, and resistance to sulfate attack as the reference concrete. In terms of environmental protection, the use of CRT glass as a component for making concrete is also very significant.
