“…Numerous studies have shown RCG's potential for use as a geomaterial since it has many of the same qualities as a natural aggregate [75]. Thoroughly cleaned glass can fully replace the role of natural granular components [76]. According to the American Society for Testing and Materials (ASTM), most cullet might be on par with clean sand.…”

Glass is a substance that is present in most houses since glass-based items are made and consumed in relatively high quantities. This has led to the buildup of glass in concerning quantities all over the world, which is a problem for the environment. It is well known that glass has several advantageous physiochemical features that qualify it as an appropriate material for use in the construction industry as an aggregate. The features include being non-biodegradable, resistant to chemical assault, having low water absorption, having high hydraulic conductivity, having temperature-dependent ductility, having alterable particle gradation, and having a wide availability in a variety of forms and chemical compositions. Because of these qualities, glass has been used in various investigations and field tests conducted in civil engineering to evaluate its effectiveness as an engineering aggregate and to develop environmentally friendly management strategies for waste glass. These studies and research have utilized glass in various forms, such as fine recycled glass, medium recycled glass, coarse recycled glass, powdered glass, and glass-based geopolymers. This study focuses on research studies that present results on physicochemical, mechanical, and durability characteristics. These studies and research contain samples of pure glass or glass as replacement percentages in materials (0–100%), including but not limited to unbound granular materials (such as recycled concrete aggregates and crushed rock). In light of the information assembled in this review article, it is legitimate to claim that glass has strong promise as a material in various civil applications.

The fiber that is most often used in dentistry is E-glass fiber, but in Indonesia E-glass fiber dental is limited by quantity and relatively expensive. E-glass fiber non dental was chosen as an alternative because the composition is almost the same as E-glass fiber dental and commonly used in the engineering world as a booster in the manufacture of gypsum panels, sculptures and automotive components. This study is aimed to determine the color stability difference between fiber reinforced composite (FRC) E-glass fiber dental and E-glass fiber non dental. This quantitative research is an experimental laboratory with a one group pretest and posttest research design. The sample is circular in shape with diameter 13 mm and height 2 mm consisted of E-glass fiber dental group and the E- glass fiber non dental group consisting of 4 samples for each group and given silane. After the color test using Spectrophotometer UV-Vis where the absorbance and wavelength values obtained will be calculated for the area so that the L*a*b* value and analysed using independent sample t-test, it was stated that there was no significant difference between the color of the fiber reinforced composite E-glass fiber dental and the E-glass fiber non dental. It is concluded that the use of E-glass fiber non dental can be used as a clinical standard because it has a good color stability value similar to that of E-glass fiber dental.

“…Due to increasing demand of glass in our daily lives, the amount of waste glass (WG) is rising and the disposal of WG becomes a major concern, as it is difficult to biodegrade and endangers the natural environment [1]. Therefore, rather than the application of WG as a landfill material, or melting the glass aiming for reproduction, which will respectively lead to space and energy consumption, reuse of WG has become popular in recent years [2]. For example, in China, about 20 million tons of waste glass is produced, and more than 50% of waste glass has been collected for recycling until 2017 [3].…”

Waste glass (WG), as a nonbiodegradable material, poses a threat to environmental protection. The reuse of WG as a raw material to replace cement or aggregate in concrete production is gaining attention for recycling purposes. However, the optimal proportion of WG in concrete mixtures and its particle size distribution are hard to determine. Large glass particles are prone to leading to the undesirable alkali–silica reaction (ASR) in concrete. Therefore, in this study, cement and aggregate in concrete mixtures are partially replaced by combinations of glass powder (<30 μm) and glass beads (0.2–1.7 mm), respectively. Glass concretes (GCs) containing waste glass at various replacement ratios (0, 10, 15, 20, and 30%) are prepared, and their flowability and compressive strength are evaluated and compared. Finally, steel tubes filled by ordinary concrete (OCFSTs) and steel tubes filled by glass concrete (GCFSTs) are fabricated and tested in axial compression. The test results show that the slump and slump flow increase when the replacement ratio is lower than 20%, and the maximum slump value (250 mm) is achieved for concrete with the use of 20% waste glass. With regard to compressive strength, as the glass replacement percentage is increased, the compressive strength of GC continues to reduce. The maximum decrease of compressive strength (merely 70% of compressive strength for original concrete) is observed in GC mixed with 20% glass, which might be attributed to the smooth surface of glass, consequently weakening the interfacial bond strength between the glass and matrix. In terms of the bearing capacity of GCFSTs, the axial compressive strength of GCFSTs decreases as more GC is used. However, no obvious reduction is observed compared to OCFSTs (less than 10% for GCFSTs containing 30% GP). Moreover, GCFSTs show greater (no less than 25% more) deformational ability at peak strength over OCFST columns, demonstrating that GC is a promising alternative for normal concrete. Finally, the feasibility of existing design codes (AISC, EC4, and GB50936-2014) to assess the bearing capacity of GCFSTs is evaluated by comparing the test and calculated results. The current codes, in general, give a conservative prediction and EC4 provides the closest value (predicted to experimental peak load ratio is 0.9).
