Using waste in the cement and concrete industry helps reduce costs and the need for large storage spaces for waste disposal. In particular, disposing of waste glass powder (WGP) from the glass industry requires significant storage capacity. Therefore, utilizing WGP as a raw material in construction is both an environmentally and economically viable solution. This study examined the workability, flexural strength, compressive strength, and splitting tensile strength of glass fiber-reinforced mortars containing WGP. A face-centered composite design was used to determine 13 test points. The fiber ratio was selected at 0%, 0.3%, and 0.6% by weight of the mixture, while WGP substitution levels were 0%, 7.5%, and 15% by weight of cement. The results indicate that adding glass fiber and WGP reduces flow value, flexural strength, compressive strength, and splitting tensile strength. However, at higher glass fiber ratios, the negative effect of WGP on flow value and compressive strength is less pronounced. The R2 values for flow value, flexural strength, compressive strength, and splitting tensile strength were 0.9983, 0.9586, 0.9069, and 0.8526, respectively, indicating a strong correlation between the tested parameters and the predictive model.

Atık cam tozu ikameli cam elyaf içeren harçların mekanik özelliklerinin ANOVA ile istatistiksel analizi

Öz

Atıkların çimento ve beton endüstrisinde kullanılması, maliyetin ve atık bertarafı için büyük depolama alanlarına olan ihtiyacın azaltılmasına yardımcı olur. Özellikle cam endüstrisinden çıkan atık cam tozunun (WGP) bertaraf edilmesi önemli bir depolama kapasitesi gerektirmektedir. Bu nedenle, WGP'nin inşaatta hammadde olarak kullanılması hem çevresel hem de ekonomik açıdan uygulanabilir bir çözümdür. Bu çalışmada, WGP içeren cam lif takviyeli harçların işlenebilirliği, eğilmede çekme, basınç ve yarmada çekme dayanımları incelenmiştir. Yüzey merkezli kompozit tasarım 13 test noktasını belirlemek için kullanılmıştır. Lif oranı karışımın ağırlığına göre %0, %0.3 ve %0.6 olarak seçilirken, WGP ikame seviyeleri çimentonun ağırlığına göre %0, %7.5 ve %15 olarak belirlenmiştir. Sonuçlar, cam lif ve WGP ilavesinin yayılma değerini, eğilmede çekme, basınç ve yarmada çekme dayanımını azalttığını göstermektedir. Bununla birlikte, daha yüksek cam lif oranlarında, WGP'nin yayılma değeri ve basınç dayanımı üzerindeki olumsuz etkisi daha az belirgindir. Yayılma değeri, eğilmede çekme, basınç ve yarmada çekme dayanımı için R2 değerleri sırasıyla 0.9983, 0.9586, 0.9069 ve 0.8526 olup test edilen parametreler ile tahmini model arasında güçlü bir korelasyon olduğunu göstermektedir.
