“…Effects of the use of waste glass as cement replacement on some mechanical properties such as CS, STS, and FS have been investigated. In this part of the study, values of CS, STS, and FS for plain concrete and concrete produced from different glass powder amounts have been collected from the research publications [ 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 ]. Then, measured strength values of concrete produced with waste glass were first normalized by plain concrete strengths.…”

In this study, the effect of waste glass on the mechanical properties of concrete was examined by conducting a series of compressive strength, splitting tensile strength and flexural strength tests. According to this aim, waste glass powder (WGP) was first used as a partial replacement for cement and six different ratios of WGP were utilized in concrete production: 0%, 10%, 20%, 30%, 40%, and 50%. To examine the combined effect of different ratios of WGP on concrete performance, mixed samples (10%, 20%, 30%) were then prepared by replacing cement, and fine and coarse aggregates with both WGP and crashed glass particles. Workability and slump values of concrete produced with different amounts of waste glass were determined on the fresh state of concrete, and these properties were compared with those of plain concrete. For the hardened concrete, 150 mm × 150 mm × 150 mm cubic specimens and cylindrical specimens with a diameter of 100 mm and a height of 200 mm were tested to identify the compressive strength and splitting tensile strength of the concrete produced with waste glass. Next, a three-point bending test was carried out on samples with dimensions of 100 × 100 × 400 mm, and a span length of 300 mm to obtain the flexure behavior of different mixtures. According to the results obtained, a 20% substitution of WGP as cement can be considered the optimum dose. On the other hand, for concrete produced with combined WGP and crashed glass particles, mechanical properties increased up to a certain limit and then decreased owing to poor workability. Thus, 10% can be considered the optimum replacement level, as combined waste glass shows considerably higher strength and better workability properties. Furthermore, scanning electron microscope (SEM) analysis was performed to investigate the microstructure of the composition. Good adhesion was observed between the waste glass and cementitious concrete. Lastly, practical empirical equations have been developed to determine the compressive strength, splitting tensile strength, and flexure strength of concrete with different amounts of waste glass. Instead of conducting an experiment, these strength values of the concrete produced with glass powder can be easily estimated at the design stage with the help of proposed expressions.

Thermal efficient sandcrete bricks are masonry units with good thermal insulating properties. Wood fiber (WF) possesses low thermal conductivity, hence, its incorporation in mortar mix results in thermal efficient masonry units. Milled glass (MG) could be added for strength enhancement. This study incorporated WF into mortar mix at a constant dosage of 5 wt.%, with varying MG proportions of 0, 5, 10, 15 and 20 wt.% and cured for 7, 14 and 28 days. The results obtained showed minimization of porosity and water absorption at increasing MG content. Density and compressive strength were enhanced as MG content increased. Flexural and splitting tensile strengths appreciated and peaked at 15 wt.% MG. Thermal performance measured demonstrated progressive appreciation in thermal conductivity while specific heat capacity followed a downtrend as MG dosage increased. The study revealed that the collage of 5 wt. % wood fiber and 15 wt. % MG yielded optimum result. The study, therefore, concludes that the addition of milled glass and wood fiber positively and significantly affected the properties of sandcrete bricks. 15 wt.% of milled glass and 5% wood fiber inclusion in sandcrete bricks are recommended for use by construction practitioners.

“…Kumar and Sood (2017) found that cement can be replaced by glass powder by up to 20% without any loss of flexural and tensile strength in all concrete variants studied. Rahman and Uddin (2018) concluded that 30% of cement replacement achieves maximum tensile strength by splitting compared to the control concrete at 28 days.…”

Kumar and Sood (2017) concluded that the tensile strength by splitting of M20 concrete increased by 39% at seven days, and 38% at 28 days compared to the reference concrete, and in M25 concrete, they noted an increase of 40% at seven days and 28% at 28 days compared to the control concrete. In addition, Zakir et al (2016) showed that the tensile strength by splitting of glass powder concrete increases by about 29% at 28 days.…”

Every year, millions of tonnes of glass waste pose terrible problems related to the environmental condition all over the world. The glass is mainly composed of silica. Its use in concrete could be a beneficial solution for the environment and also economic problems. In this mini review, the different possibilities of the valorization of glass waste by substitution of aggregates and cement in concrete have been explored. Its effects on the physicochemical and mechanical characteristics were examined in the main research in this direction. The use of waste glass in concrete can offer an improvement in concrete performance and an asset for participation in sustainable development by reducing this waste.
