“…Numerous studies [34][35][36][37][38][39][40][41] attempt to find ways of using materials for the production of ceramics, binders, mortar, concrete, insulation materials, for the production of glass fibers, foamed glass, mats, insulation plates, laminates and bituminous materials. Tests [10,40,42] were carried out to determine possibilities of applying cullet among others as replacement for natural aggregate to concrete, substitute of natural soils, or construction of roads and subgrades.…”

The article presents results obtained during testing of concrete based on CEM I 42.5R Portland cement, fine and coarse aggregate, glass, volatile ash, and superplastifier. The concrete mixture was modified using filler consisting of bromosilicate heat resistant cullet. Recycled aggregate was added to the batch. Samples for the need of testing were produced as (100 × 100 × 100) mm cubes. Before commencing proper tests, samples have been heated within the temperature range of 20–800 °C. Tests carried out during the proper testing procedure included tests of compressive strength, elevated temperature, impact strength, as well as macroscopic tests of the contact area. The obtained test results have provided proof of there being a possibility of producing special concrete, modified by products obtained from heat resistant cullet. This type of is generally characterized by satisfactory performance parameters. The average compressive strength for concrete modified by a 10% of heat resistant cullet was determined as 43.6 MPa and 48.3 MPa respectively after 28 and 180 days of curing.

“…In recent years, supplementary cementitious materials (SCM), such as GGBS, fly ash, silica fume and waste glass have attracted more attention as ingredients in concrete manufacture, combined with OPC [2,3]. However, the application of SCMs mostly relies on the pozzolanic reaction with the hydration products of cement clinkers [4][5][6]. In some studies, the addition of SCMs even causes negative effects on the performance of conventional concrete [7,8].…”

“…Since waste glass contains a high amorphous content of silica, a potential of pozzolanic reaction has been identified [18]. Some studies reported applying waste glass as SCM in conventional concrete, the microstructure improvement was identified [5,19]. In previous studies, waste glass was also used as ingredient, combining with GGBS or fly ash for the alkali activated concrete production, such as a binder, or even activator to replace water glass [20][21][22][23].…”

This paper illustrates the application of waste glass powder as part of the binder in slag-fly ash systems activated by NaOH and NaOH/Na 2 CO 3 activators. To evaluate the reaction kinetics, reaction products, mechanical properties, and durability performance of glass powder modified alkali activated slag-fly ash systems, calorimetry test, X-ray diffraction, FTIR, strength test, drying shrinkage tests, and carbonation test were conducted. From the isothermal calorimeter results, glass powder shows a higher reactivity compared to fly ash but still lower than slag. The reaction products of glass power modified samples exhibit an enhancement of polymerization degree of Si-O-T, observed in FTIR. As a consequence, higher drying shrinkage exists in glass modified mortars. The mechanical performance of different samples is mostly controlled by the Ca/Si of dry mixtures and activator type. After the slag-fly ash binder system was modified by the waste glass, a significant enhancement of resistance to carbonation was identified, especially for NaOH/Na 2 CO 3 activated mortars, which show an increase of 300% on the carbonation resistance ability compared to the reference sample. The Na/(Si ? Al) ratio of dry mixtures exhibits a positive correlation with carbonation resistance.

“…Recently conducted studies [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ] enable the determination of the suitability of using waste materials for the production of ceramics, binders, mortar, concrete, plaster, bituminous materials etc. For testing requirements, use is made of various types of cullet, from car glazing [ 25 ], soda-lime glass from containers [ 26 , 27 , 28 ], glass from technological lines of the pharmaceutical industry [ 29 , 30 , 31 ], cathode ray tubes for TV sets and computer screens [ 32 , 33 ], float glass from window glazing [ 5 ], glass from fluorescent lamps [ 13 ], glass from heat resistant dishes [ 34 ] and mirrors, safety glass, crystal glass, and colourless, green and brown packaging glass [ 34 , 35 , 36 , 37 , 38 , 39 ] among others.…”

“…Replacing cement in the concrete mixture with crushed glass powder [ 37 , 38 , 39 ] allows the attainment of a composite characterised by better workability and improvement of compressive and flexural strength after a prolonged curing time. Recyclate is characterised by pozzolanic reactivity, which is correlated with average compressive strength [ 10 , 51 ].…”

Reuse of Heat Resistant Glass Cullet in Cement Composites Subjected to Thermal Load

The article describes the possibility of using waste glass cullet as an alternative aggregate for the production of cement composites. Three concrete mixes based on Portland cement CEM I 42.5 R with different contents of recyclate were designed. Borosilicate glass cullet was introduced into the batch by reducing the content of natural aggregate by 0%, 2.5% and 7.5%. Apparent density, water absorption and compressive strength at elevated temperature were measured. The temperature distribution, in cubic samples, was followed by thermocouples. The elements were heated in a special furnace at the temperatures of 200 °C, 400 °C, 600 °C and 800 °C. The composite topography and phase composition were observed using X-ray energy scattering electron microscopy. The results show that the appropriate modification of the cement composite with 2.5% heat-resistant glass cullet improves both the thermal and mechanical properties. Compressive strength reaches an average value of 48.6 MPa after 28 days. The increase in temperature weakens the structure of the composite. It was found that the obtained cement composite has good physico–chemical properties. The research results are presented in the article.
