“…Aliabdo et al reported that the CS of mortar was increased up to 9% by the utilization of 10% RGP as an alternative cement material. Similarly, Omran et al indicated that mechanical property and resistance to chloride–ion penetration of concrete incorporating RGP improved because of its pozzolanic activity. In addition, the porosity and water absorption of concrete containing RGP reduced owing to its densification of microstructure.…”

This study presents the effects of water curing (WC) and steam curing (SC) on the fresh and hardened properties of high-performance mortar (HPM) incorporating recycled glass powder (RGP). In addition, this study evaluates the environmental effects of RGP. For this purpose, HPM samples were prepared in which cement was partially replaced by RGP ranged from 0% to 20% by steps of 5% increment.Tests were performed on fresh mortar involved slump flow diameter, and the hardened properties of HPMs incorporating RGP (HPMRGP) were evaluated via mechanical and durability tests at 28th and 56th days, respectively. In addition, microstructural investigations (scanning electron microscopy/energy-dispersive X-ray spectroscopy, thermogravimetric analysis/differential thermal analysis analyses) were performed to support the mechanical and durability performances of HPMs exposed to SC and WC. Finally, life cycle assessment of HPMs was conducted through cradle-to-gate life-cycle impact assessment approach. Based on all these test results, it can be stated that the best results were obtained from HPMs containing 20% RGP.

“…Therefore, the use of RGP as a viable SCM in addition to silica fume, fly ash and blast furnace slag has received increased awareness due to the rising cost of local virgin materials and the environmental impact of replacing cement in construction industry [7][8][9][10][11]. In addition, the finely ground (38-45 µm) RGP with high silica content (SiO2 > 70%), amorphous nature and high surface area propose that RGP could be used as an alternative SCM to partially replace cement in concrete or mortar [12][13][14][15]. It is known that, SCMs are widely used in concrete or mortar to extend their service life and develop their durability characteristics [16].…”

This research presents the basic durability properties of standard mortars (SMs) produced with recycled glass powder (RGP). In this study, six SM mixtures as well as control mixture were designed with constant water/binder (w/b) ratio of 0.48. In the mixtures, cement was replaced by RGP partially ranging from 0% to 30% by steps of 5% increment. Firstly, the slump flow diameters of SMs are determined and then the basic durability properties of SMs were observed in terms of water sorptivity, rapid chloride permeability and gas permeability. Finally, the relations between basic durability properties were determined for 7 and 28 days. According to test results, it is found that the RGP increased the workability of SMs. In addition, the highest durability performance was determined for SM incorporating 5% RGP. However, basic durability performances of SMs incorporating 10% RGP were also identified as higher than that of the control mixture. When the correlation coefficients are considered, strong relationships between durability properties are determined.Bu araştırmada geri dönüştürülmüş cam tozuyla (GDCT) üretilen standart harçların (SH) temel durabilite özellikleri değerlendirilmektedir. Bu çalıșmada, kontrol karışımının yanı sıra altı SH karıșımı 0,48 sabit su/bağlayıcı oranıyla tasarlanmıştır. Karışımlarda, çimento %0'dan %30'a kadar %5 artışlarla kısmen GDCT ile yer değiştirilmiştir. İlk aşamada, SH'lerin yayılma çapları belirlenmiş, sonrasında SH'lerin temel durabilite özelliklerinden kılcal su geçirimliliği, hızlı klor geçirimliliği ve gaz geçirimliliği sonuçları üzerine etkileri gözlemlenmiştir. Son olarak, temel durabilite özellikleri arasındaki ilişkiler 7 ve 28 gün için belirlenmiştir. Deney sonuçlarına göre, GDCT'nin SH'lerin işlenebilirliğini artırdığı tespit edilmiştir. Ayrıca, en yüksek durabilite performansı %5 GDCT içeren SH için belirlenmiştir. Bununla birlikte, %10 GDCT içeren SH'lerin temel durabilite performanslarının kontrol karışımından daha yüksek olduğu tespit edilmiştir. Korelasyon katsayıları değerlendirildiğinde, durabilite özellikleri arasında güçlü ilişkiler olduğu tespit edilmiştir.Anahtar Kelimeler: Standart harç; durabilite özellikleri; geri dönüştürülmüş cam tozu; korelasyon katsayısı *Corresponding author / Sorumlu yazar.

Abstract. Ground-glass pozzolan (G) obtained by grinding the mixed-waste glass to same fineness of cement can act as a supplementary-cementitious material (SCM), given that it is an amorphous and a pozzolanic material. The G showed promising performances in different concrete types such as conventional concrete (CC), high-performance concrete (HPC), and ultra-high performance concrete (UHPC). The current paper reports on the characteristics and performance of G in these concrete types. The use of G provides several advantages (technological, economical, and environmental). It reduces the production cost of concrete and decrease the carbon footprint of a traditional concrete structures. The rheology of fresh concrete can be improved due to the replacement of cement by non-absorptive glass particles. Strength and rigidity improvements in the concrete containing G are due to the fact that glass particles act as inclusions having a very high strength and elastic modulus that have a strengthening effect on the overall hardened matrix.
