Concrete typically emerges as the superior choice in terms of strength, adaptability, longevity, noise reduction, energy efficiency, and it additionally possesses the advantage of being fully recyclable. The excessive consumption of natural resources such as sand in traditional concrete production poses environmental concerns and makes concrete production as a significant contributor to greenhouse gas emissions. By using waste glass powder as a partial substitute for fine aggregate, the study explores the potential to lower the carbon footprint of concrete, to reduce the reliance on virgin materials, minimize waste generation, and promote sustainable practices in the construction sector and finally contributing to climate change mitigation and environmental stewardship. Also, it can offer cost savings, as waste glass is often readily available at low cost, reducing the dependence on expensive virgin materials. This article assesses the workability, durability, compressive, flexural, and tensile strength of concrete when waste glass powder is used as a partial substitute for fine aggregate. Additionally, it provides a comprehensive summary of the current state of knowledge on this topic, evaluating the outcomes of previous studies, methodologies, and limitations. This review paper aids in understanding the progress made in this field and identifying areas that require further investigation. Overall, preparing a review paper on the performance of waste glass powder as a partial substitution of fine aggregate in concrete consolidates existing knowledge, evaluates performance, identifies benefits, challenges, and guides future research.

“…A numerical model was used to calculate the propagation of micro-particle to credit deformation of structures of composite. Results shew breaks with the loading curves [4]. Experiment method was used to determine the volumetric and water retention behaviors of a compacted clay during soaking and desiccation considering the influences of freeze-thaw (FT) cycles and saline intrusion.…”

“…An experiment method to control the volumetric strains by changing the suction or stress of an expansive bentonite/silt mixture treated with lime using an odometer machine. Results presented that at different suction forces (2,4, and 8 MPa), suction increased and fine particles of bentonite became swelled larger than with no loading [6]. Full-field measurements of strain loclocalization sandstone by neutron tomography and 3D-volumetric digital image correla-tion were used to determine clearly the deformation of sandstone.…”

Finite element method of the influence evaluation of the percentage of fine particles of marine clay at the different depth variations to the total volumetric strain of the soft clay ground is determined by the Viet Nam standard TCVN 4196:2012; TCVN 4102:2012; TCVN 4197:2012; TCVN 4199:2012. Results show clearly the percentage of the fine clay particle and the total volumetric strain (ε) with depths. The minimum value of 12% and 0.00002617 at 19.3m depth; whereas the maximum value of 38% and 0.00002609 at 25.3m depth. Moreover, a consideration of the relationship between Internal friction angle, Cohesive force, Water content, Saturation, Porosity, Viscosity, and Plasticity index with depths. Results show remarkably the increasing of the depths as the variations of the percentage of fine particles of marine clay and cohesive force, viscosity, water content, and porosity; compared with the decrease of the plasticity and internal friction angle. It is easy to conclude that the total volumetric strain of the soft clay ground is a stable and safe state to use and design the building, construction, and reference of engineers, geologists, scientists, and so on in the future.

“…Many recycled materials are used in concrete by replacing them with cement or aggregates [19][20][21]. Recycled crushed glass is used in numerous studies around the world as a substitute for CA and FA for the development of sustainable concrete [22][23][24]. One of the most important of these waste materials is crushed waste glass (CWG) in aggregate size.…”

In this study, ground glass powder and crushed waste glass were used to replace coarse and fine aggregates. Within the scope of the study, fine aggregate (FA) and coarse aggregate (CA) were changed separately with proportions of 10%, 20%, 40%, and 50%. According to the mechanical test, including compression, splitting tensile, and flexural tests, the waste glass powder creates a better pozzolanic effect and increases the strength, while the glass particles tend to decrease the strength when they are swapped with aggregates. As observed in the splitting tensile test, noteworthy progress in the tensile strength of the concrete was achieved by 14%, while the waste glass used as a fractional replacement for the fine aggregate. In samples where glass particles were swapped with CA, the tensile strength tended to decrease. It was noticed that with the adding of waste glass at 10%, 20%, 40%, and 50% of FA swapped, the increase in flexural strength was 3.2%, 6.3%, 11.1%, and 4.8%, respectively, in amount to the reference one (6.3 MPa). Scanning electron microscope (SEM) analysis consequences also confirm the strength consequences obtained from the experimental study. While it is seen that glass powder provides better bonding with cement with its pozzolanic effect and this has a positive effect on strength consequences, it is seen that voids are formed in the samples where large glass pieces are swapped with aggregate and this affects the strength negatively. Furthermore, simple equations using existing data in the literature and the consequences obtained from the current study were also developed to predict mechanical properties of the concrete with recycled glass for practical applications. Based on findings obtained from our study, 20% replacement for FA and CA with waste glass is recommended.
