Özet:

 Brick dust is a waste material with pozzolanic nature. It is important to recycle this waste material without causing environmental pollution. In this study, it was aimed to evaluate the usability of waste brick dust WBD in cement in terms of 7 and 28-day compressive strength performance. For this purpose, WBD was added as a replacement for Portland cement CEM I 52.5 N in amounts of 0, 2.5, 5, 7.5 and 10 by weight in accordance with TS EN 197-1 and compressive strength test was conducted. Based on the experimental results, surface response methodology RSM analysis was performed in order to estimate the 7 and 28-day compressive strengths of WBD-substituted cement mortar with the help of statistical model. The results showed that increasing the pozzolanic additive WBD caused a decrease in mechanical strength at 7 and 28 days short and medium term. At a 95  level of confidence, the effect of multiple factors on the target response was studied using statistical analysis of analysis of variance ANOVA results. The coefficient of determination R2 value obtained as 0.99 show the reliability and performance of the proposed model. As a result of optimization, the optimal response value for compressive strength was found to be 60.57 MPa and the desirability value was found to be 1. In this study, it was concluded that the optimization performed using RSM is an effective approach for the mixed design of cements.

 Tuğla tozu puzolanik özellik gösteren atık bir malzemedir. Bu atık malzemenin çevre kirliliğine neden olmadan geri kazanımı önem arz etmektedir. Bu çalışmada atık tuğla tozunun çimento içerisinde kullanılabilirliğinin 28 günlük basınç dayanımı performansı açısından değerlendirilmesi amaçlanmıştır. Bu amaçla atık tuğla tozu ATT, TS EN 197-1 standardına uygun olarak ağırlıkça 0, 2.5, 5, 7.5 ve 10 oranlarında Portland çimento CEM I 52.5 N yerine ikame edilmiş ve basınç dayanımı deneyleri gerçekleştirilmiştir. Deneysel sonuçlara dayalı olarak ATT ikameli çimento harcının 7 ve 28 günlük basınç dayanımlarını istatistiksel model yardımıyla tahmin etmek amacıyla yanıt yüzey metodolojisi YYM analizi yapılmıştır. Sonuçlar, puzolanik katkının ATT artmasının, 7 ve 28 günde kısa ve orta vadede mekanik dayanımda azalmaya neden olduğunu göstermiştir. 95lik bir güven seviyesinde, birden fazla faktörün hedef yanıt üzerindeki etkisi, varyans analiz ANOVA sonuçlarının istatistiksel analizi kullanılarak incelenmiştir. 0,99 olarak elde edilen belirleme katsayısı R2 değeri, önerilen modelin güvenilirliğini ve performansını göstermektedir. Optimizasyon sonucunda basınç dayanımı için optimal yanıt değeri, 60.57 MPa ve istenirlik değeri 1 olarak bulunmuştur. Bu çalışmada, YYM kullanılarak yapılan optimizasyonun çimentoların karma tasarımı için etkili bir yaklaşım olduğu sonucuna varılmıştır.
