“…The morphology of the used foam glass aggregate with different aperture sizes is shown in Figure 2. The used foam glass aggregate in the present study was previously characterised and analysed for its atomic and weight concentration [12]. The loose bulk density is around 170 kg/m 3 , with high porosity reaching 92.7%.…”

“…The gas stays blocked in the form of bubbles due to its appropriate viscosity, and as it cools, it produces spores, which form the porous structure of the glass foam [8]. The porosity of foam glass materials reaches around 59.4% [9], 60% [10], 77% [11], 88% [12], 89.1% [13], 89.5% [9], and 96% [14] of the total volume depending on the type of raw materials and foaming technology used.…”

The use of glass waste in the construction industry has a high potential of leading to a higher recycling percentage. Foam glass aggregate (FGA) is around 98% recycled glass waste of various origins and has good insulation properties with big grain size distributions ranging between 10 mm and 60 mm. FGA has a wide range of applicability in the construction industry, which significantly differs from each implementation in the case of built-in conditions of the material. Therefore, investigating the impact of different compaction ratios, temperature, and relative humidity conditions on the thermal performance of such material is very important. In the present work, the samples of foam glass aggregates have been prepared with four different compaction ratios (10%, 20%, 30%, and 40%) to measure their impact on the material’s mechanical and thermal insulation properties. The obtained results revealed that the dry density property of the material linearly increased with elevated compaction ratios. In contrast, the submergence density did not follow the same trend behaviour under the same circumstances. The vertical strain of the foam glass aggregates decreased with increased compaction ratios, and a significant correlation behaviour was observed between the vertical strain and increased compaction ratios at high compressional loads. The material’s thermal conductivity increased with increasing compaction ratios in both 50% relative humidity and 95% relative humidity, while for the submergence condition, a significant decrease in their values was observed after compacting the material by 40%. The thermal conductivity is tested at 10 °C and 30 °C using the TLS and GHP methods. The thermal resistance of foam glass aggregate layers was calculated based on the measured results, showing an approximately linear decreasing trend with increasing compaction ratios. While the submerged foam glass aggregate samples demonstrated stable thermal resistance values at 30% compaction, by raising the compaction ratio to 40%, the material’s thermal resistance increased once again. The experimental results also found the temperature conversion coefficients, which can be used to convert the compacted FGA materials’ thermal conductivity to the temperature experienced in a different built-in state than the laboratory measurements. Our study demonstrates the broad usability of foam glass aggregate as a compacted thermal insulating layer in the building industry.

“…By using 800–900 °C temperature [ 4 ], three types of thermal insulation products can be made from crushed and milled glass powder: foam glass thermal insulative tiles [ 5 ], foam glass chips and foam glass granules. Foam glass granules can be gray [ 6 ] or white-colored [ 3 ]. White color and a small size is obtained from granules by using bleaching production process method as well as using raw materials that do not have dyeing oxides.…”

“…Cement mixtures with average coarseness and high coarseness foam glass granules properties are investigated, as well as their composite resistance to sulfate corrosion [ 17 , 18 ]. Even though foam glass granule usage in cement composites is currently investigated by researchers and there are submitted research results [ 2 , 4 , 6 , 10 , 12 ], foam glass granule usage in dry glue mixtures is not investigated enough. There is no investigation of foam glass granule effect on tile glue properties.…”

In the last few years, ceramic tiles and tiles from natural rock with higher measurements were used. A huge amount of tile glue is used for high-measurement tile gluing due to a special gluing technology, which is characterized by a thicker glue layer. Due to this, a higher and higher amount of tile glue is used up during decorating. Regular tile glue mixture uses up to about 50–60% cement (according to mixture mass). In carried-out experiments, a lower amount of cement was used in tile glue mixture production (30%). Additionally, 5%, 10%, 15%, 20% and 25% of sand was replaced with small foam glass granules. These granules are made from glass waste. By using foam glass granules, lighter tile glue mixtures were produced, while reducing the cement amount can lower energy usage and CO2 emissions into the atmosphere. The main properties of tile glue were investigated as follows: flow of mixture, density, compressive strength, bending strength, tensile-adhesive strength, slip and water absorption. The properties obtained during the research prove that newly produced tile glue mixtures fulfill all requirements given to these types of mixtures. A total of 25% of foam glass granule from filler mass can be used in tile glue production.

“…[27,28] In contrast, the mechanical characterization of cellular foam has been a topic of extensive laboratory research where authors tested the material using different and standard laboratory testing (oedometric test, shear box test). [22,23,29,30] Furthermore, Zegowitz [31] showed the possible use of cellular glass aggregates as thermal insulator under floor slabs subjected to very long-term loading period. In the context of infrastructure construction, the use of foam glass as an alternative to granular materials is possible particularly in mitigating vertical loads on soft subgrades.…”

Cellular glass aggregates made from recycled glass are increasingly being used in civil engineering and infrastructure applications. However, as this material is relatively new and innovative, it’s necessary to obtain a complete mechanical characterization for its usage in the civil engineering field. This paper investigates the dynamic properties of cellular glass aggregate with the aid of a large‐scale triaxial apparatus (300 mm diameter and 600 mm height) under cyclic loading. The experimental procedure for building the samples is presented with a brief description of the test setup. A series of cyclic triaxial tests were performed to characterize and evaluate the dynamic properties of the material which are of interest in the seismic approach (Young’s modulus and damping ratio).This article is protected by copyright.
