“…Adaway and Wang [23] reported that the increase in compressive strength above the control mix may be attributed to the angular nature of glass aggregate, which has a greater surface area than the naturally rounded sand particles. In contrast, the compressive strength of concrete bricks decreased with the increase of waste glass up to 30%, caused by the weak bond between waste glass and cement paste due to the surface of waste glass is smoother than sand causing poorly mechanical anchorage between cement paste and waste glass [7,24]. The water absorption and density of concrete bricks with different replacements of waste glass at 7, 14, and 28 days are presented in Fig.…”

The objective of this research is to manage waste glass in Koh Sichang, Chonburi province, used as a partial fine aggregate replacement in concrete brick production. An experimental approach aimed to determine the level of waste glass replacement for the optimal compressive strength. Five samples of 0, 10, 20, 30, and 100% waste glass aggregates by weight were tested at 7, 14, and 28 days. The microstructure and mineralogical phases of the concrete bricks were investigated by scanning electron microscopy and X-ray diffractometry, respectively. The experimental results showed that the compressive strength was improved by increments in replacing waste glass up to 20%; in contrast, the compressive strength was decreased with an increase of waste glass of over 20% in concrete bricks. The optimum compressive strength of concrete brick was 20% by weight, which had the highest values (46.51, 47.41, and 48.49 MPa at 7,14, and 28 days, respectively) and the lowest water absorption. Therefore, waste glass can be used as a partial fine aggregate for producing concrete bricks, and it can be employed as an alternative material for waste glass management.

“…The process of obtaining recycled aggregate from concrete is complicated, and it comprises assessing concrete source, selective facility demolishing, crushing larger elements, removal of any present contamination, initial and elementary concrete crushing, fractionation, and the improvement process [21].…”

“…For years now researchers have been studying the impact of the amount of added crushed recycled aggregate on concrete strength. Results compiled and presented in studies [14,21,[27][28][29][30][31][32] do not provide an unequivocal assessment of the impact exerted by cullet on concrete strength. Researchers argue that as the contents of recyclate are increased, the compressive strength of concrete tends to drop.…”

The article presents results obtained during testing of concrete based on CEM I 42.5R Portland cement, fine and coarse aggregate, glass, volatile ash, and superplastifier. The concrete mixture was modified using filler consisting of bromosilicate heat resistant cullet. Recycled aggregate was added to the batch. Samples for the need of testing were produced as (100 × 100 × 100) mm cubes. Before commencing proper tests, samples have been heated within the temperature range of 20–800 °C. Tests carried out during the proper testing procedure included tests of compressive strength, elevated temperature, impact strength, as well as macroscopic tests of the contact area. The obtained test results have provided proof of there being a possibility of producing special concrete, modified by products obtained from heat resistant cullet. This type of is generally characterized by satisfactory performance parameters. The average compressive strength for concrete modified by a 10% of heat resistant cullet was determined as 43.6 MPa and 48.3 MPa respectively after 28 and 180 days of curing.

“…As far as the ultimate compressive strength (UCS) is concerned, Sadiqul Islam (Sadiqul Islam, 2017) reported that use of RG powder as a PC replacement which is finer than 100 μm size increase pozzolanic reactivity of glass and could improve mechanical and durability performances of glass incorporated concrete. Pozzolanic contribution of glass either as a sand (Arulrajah, 2017;Bostanci, 2018;Corinaldesi, 2016;Guo, 2018;Harbi, 2017;Idir, 2011;Nunes, 2013;Paul, 2018;Penacho, 2014;Rashid, 2018;Soliman, 2017) or cement (Carsana, 2014;Du, 2017;Paul, 2018) replacements was reported earlier. Özkan (Özkan, 2008) also reported that the effect of glass on the strength development increased when it is finely ground.…”

“…Siad (Siad, 2018) stated that RG powder with average grain size of 20 μm acted as a catalyst rather than pozzolanic property and contributed to early strength development. Another study by Rashid (Rashid, 2018) aggregate size of 20 mm reduced the UCS at 7 and 28 days as the glass waste increased. However, strength loss of 10% waste glass mix was observed to be negligible.…”

Reduction in the availability of natural raw materials is forcing concrete industry to adopt environmentally friendly approaches. Utilization of recycled materials in concrete production has become a popular approach to lessen the environmental footprint of the concrete production. Glass is one of the most consumed materials that can be easily collected and recycled. Glass use in concrete production may potentially reduce the amount of natural raw materials used in concrete production and prevents the use of virgin lands for landfilling purposes. Reported work initially investigates the fresh and hardened performances of recycled glass sand (RGS) incorporated concrete and further sustainability analysis was also carried out. As an initial attempt for this particular research, natural sand was replaced by 10% RGS in aiming to assess their suitability from the environmental and economical sustainability point of view. In this regard, concretes made with partially substituted RGS (10% by mass replacement) with equivalent 28-day compressive cube strengths of 30 N/mm 2 and 45 N/mm 2 were produced. The results showed that the use RGS could improve concrete fresh properties slightly. Use of RGS by 10% as a replacement to natural fine aggregate was observed to reduce compressive strength at early ages by approximately 10% and 14% but strength losses were minimized to 0.6% and 10.5% for 30-RGS and 45-RGS respectively at 28-days compared to conventional concrete mixes. Ultrasonic pulse velocity results showed that RGS incorporation provide either similar or denser matrix compared to conventional mixes. Results indicated that use of RGS as a fine aggregate replacement could lead to environmentally sustainable concrete production if it is supplied within range of 14.4 km based on eCO2 emissions. It is also revealed that RGS could provide cost-efficient concrete production on the condition of supplied from closer facilities.
