“…Grounded glass (finer than 38 μm in its size) can increase concrete strength and durability through its pozzolanic behaviour [9,10]. Besides it can replace cement partially in certain concrete types [11][12][13][14].…”

The aim of this study is to investigate the efficiency of using green ultra-high-performance concrete (GUHPC) with corrosion resistant alloy steel (MMFX) Bars in overcoming concrete cracking and steel corrosion, which will help in reducing inspection, maintenance, and repair works. To do so, a nonlinear finite element (FE) analysis was carried-out to model full-scale concrete beams which are often subjected to cracks during its service life time. The obtained results were compared with experimental data and the comparison was most satisfactory. In addition, a comparison was made between the proposed materials and traditional reinforced concrete in terms of crack widths, the intensity of cracks and service life period. The obtained results showed that using GUHPC and MMFX as a construction material in concrete structures provides high stiffness, high strength, enhanced service life and crack control beside its cost efficiency.

“…Previous studies have demonstrated that micro-scale size RGPs develop the durability performances of concrete or mortar [8-10, 17,18]. Additionally, the pozzolanic property of RGP with a micro-scale size distribution contributes improvement in the mechanical and durability performances of concrete or mortar [7,9,10,19,20]. However, there can be some negative effects of RGP usage in concrete or mortar.…”

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.

“…Recycled glass powder, fluid catalytic cracking catalyst residue and limestone powder are some of the supplementary cementitious materials (SCM) that can be used as a partial substitution of Portland cement in UHPC [12,[19][20][21]. There are several UHPC mixture proportions from the literature using glass powder or limestone powder as a component of UHPC's binder.…”

Ultra-high-performance concrete (UHPC) is the essential innovation in concrete research of the recent decades. However, because of the high contents of cement and silica fume used, the cost and environmental impact of UHPC is considerably higher than conventional concrete. The use of industrial byproducts as supplementary cementitious materials, in the case of recycled glass powder and fluid catalytic cracking catalyst residue (FCC), the partial substitution of cement and silica fume allows to create a more ecological and cost-efficient UHPC. This research presents a study to determine the possibility of partial substitution of cement by FCC in a previously optimized mixture of ultra-high-performance concrete with recycled glass. The results demonstrate that compressive strength values of 150 and 151 MPa without any heat treatment can be achieved, respectively, when replacing 11% and 15% of the cement with FCC, for a determined amount of water and superplasticizer, compared to 158 MPa obtained for the reference UHPC without any FCC content. The rheology of fresh UHPC is highly decreased by replacing cement particles with FCC.
