“…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.

“…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].…”

Waste glass as binder in alkali activated slag–fly ash mortars

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.

“…To overcome these limitations, several studies related to the utilization of WG as an aggregate and powder have been performed. For example, WG has been adopted as a construction material in paving blocks [ 3 ], road application (so-called glasphalts) [ 12 ], shielding cement mortar [ 13 ], screeds [ 14 ], architectural mortars [ 15 ], high performance concrete [ 16 ], self-cleaning concrete [ 17 ] and bactericidal mortars [ 18 ]. WG aggregates were also utilized to prepare alkali-activated materials such as blast furnace slag or fly ash [ 19 ] and alkali-activated concretes [ 20 ].…”

“…The same result was reported in [ 24 ] that all cement mortars containing soda lime-glass met the permissible limits at satisfactory level. Nevertheless, many researchers have demonstrated that ASR can be effectively controlled by optimizing the mix composition, through the use of supplementary cementitious materials, such as fly ash, ground granulated blast furnace slag, metakaolin, silica fume or even waste glass powder [ 17 , 23 , 25 , 26 ].…”

Recently, the recycling of waste glass has become a worldwide issue in the reduction of waste and energy consumption. Waste glass can be utilized in construction materials, and understanding its effects on material properties is crucial in developing advanced materials. In this study, recycled crushed and expanded glasses are used as lightweight aggregates for concrete, and their relation to the material characteristics and properties is investigated using several approaches. Lightweight concrete specimens containing only crushed and expanded waste glass as fine aggregates are produced, and their pore and structural characteristics are examined using image-based methods, such as scanning electron microscopy (SEM), X-ray computed tomography (CT), and automated image analysis (RapidAir). The thermal properties of the materials are measured using both Hot Disk and ISOMET devices to enhance measurement accuracy. Mechanical properties are also evaluated, and the correlation between material characteristics and properties is evaluated. As a control group, a concrete specimen with natural fine sand is prepared, and its characteristics are compared with those of the specimens containing crushed and expanded waste glass aggregates. The obtained results support the usability of crushed and expanded waste glass aggregates as alternative lightweight aggregates.
