Concrete is the most used man-made material and foamed concrete is a type of concrete widely known with high workability, low density and excellent thermal and sound insulation properties. Its global market has also been predicted to increase. Growing of population and economy, along with urbanization generate wastes which increase yearly. One of the solutions to reduce waste in landfills is by using waste in manufacturing. Glass, classed as a form of ceramic waste (GCW) has been left in the landfills unrecycled due to the challenges it causes. The primary purpose of this research is to find the optimal GCW composition as a quartz sand additive for Foamed Concrete-based Glass Ceramic Waste (FC-GCW) which will reduce the amount of unrecycled GCW that ends upin landfills while producing a sustainable product. The samples were prepared by grinding the GCW and mixing varying percentages of GCW (0, 5, 10, 15, 20, 25, and 30%) with a consistent quantity of cement, quartz sand, water, and foam. Physical (density, water absorption, porosity and Energy Dispersive X-ray (EDX)) test and analysis and mechanical (compressive strength) test were performed on the samples. During physical tests, the density increased as the GCW percentage increased, but water absorption andporosity decreased. FC-GCW 20% had appropriate density, water absorption, and porosity values of 0.887 g/cm3, 22.6 %, and 88.9%, respectively, which demonstrated that the material is lightweight and porous.For EDX analysis between FC-GCW control and FC-GCW 20%, it was found that when GCW was included, the weight percentage of Oxygen and Calcium decreased while the weight percentage of Silica increased, showing GCW increased Silica content, and pozzolanic reaction occurred to from Calcium Silicate Hydrate (C-S-H) gel.For mechanical testing, it was discovered that FC-GCW 20% had the highest average compressive strength of 0.94 MPa and 2.01 MPa for 7 and 28 days, respectively. This research's contribution can be applied to areas where low densities are preferred and low compressive strength is required, such as of road sub-base, fire breaks, raising floor level, void fill, harbour fill, bridge abutments and ground stabilization.

“…The expanded glass (EG) is a type of ultra-lightweight aggregate capable of enhancing various concrete characteristics. It can partially replace natural aggregates and can change the properties of the concrete [ 7 ]. EG has been the subject of research due to its characteristics, such as stiffness, lightness, and compressive strength and, furthermore, it normally requires less energy for its production compared to conventional materials [ 2 ].…”

“…Currently, numerous amounts of waste glass are collected from various industrial plants and then dumped. The EG aggregate is prepared from waste glass from various industries [ 7 ]. By incorporating EG into concrete, the amount of glass waste and natural aggregate excavation are reduced and concrete properties can be changed, making it more sustainable.…”

“…A drastic decrease in compressive strength may not be the case when EG is used. Sharma et al [ 7 ] investigated the influence of the variation in particle size distribution on the properties of concrete. It was concluded that the smaller the size of the aggregate particle, the more the compressive strength will develop and, on the contrary, the bigger the size of the aggregate particles, the less the compressive strength will develop.…”

“…This is due to the smaller size and smooth surface of the EG, which improves the bonds between the cement matrix and the aggregate particles. Additionally, it densifies the microstructure of the concrete by acting as a filler for the pores inside the concrete [ 7 ]. Chung et al [ 8 ] concluded that lightweight aggregate concrete could be more useful to mechanical operations by reducing insulation loss.…”

In the construction industry, the selection of sustainable materials leads to a movement towards more sustainable construction. In this study, lightweight aggregate shotcrete based on expanded glass (EG) and expanded clay (EC) is investigated. The goal of the study is to determine the influence of EG and EC inclusion on the properties of shotcrete. Ordinary Portland cement (OPC) powder with supplementary cementitious materials, such as silica fume and ground glass waste, are used as binders. The mechanical, physical and morphological properties, as well as the mineral and oxygen compositions, are obtained through compressive and flexural strength tests, thermal conductivity measurements, scanning electron microscopy with energy dispersive X-ray spectrometry (SEM–EDX), X-ray diffraction (XRD) and X-ray fluorescence (XRF) analysis. In this study, the mechanical, physical and thermal properties and waste utilization as cement supplementary materials are balanced. The shotcrete samples show that a density of 790 kg/m3 had a good thermal performance (thermal conductivity coefficient of 0.174 W/(m·K)) with the sufficient compressive strength of 6.26 MPa.

This project investigates the use of foamed glass aggregates in lightweight precast concrete. Precast mixes are evaluated for compression and split‐tension strength, and durability is assessed through rapid chloride permeability, thermal conductivity, alkali silica reactivity, and freeze–thaw performance. Mixes containing a 100% or 50% replacement of gravel with foamed glass aggregates are evaluated. The 100% mixes have a 28‐day compression strength = 23.3–27.89 MPa which is acceptable per structural lightweight concrete standards (ASTM C330), but the split‐tension strength falls short of ASTM C330 requirements. The 50% mixes have acceptable strength but exceed the maximum density allowed for lightweight concrete in ASTM C330. The mixes exhibited low–moderate permeability but poor freeze–thaw resistance. All of the proposed mixes with one exception have acceptable expansion due to alkali silica reactivity. The thermal conductivity of the mixes varies from typical lightweight to normal weight concrete ranges with respect to the aggregate replacement ratio.
