Geri Dönüşüm Agregalı Betonların Erken Yaş Dayanımlarını Tahmin Eden Matematiksel Modellerin Geliştirilmesi
Öz
Bu çalışmanın amacı farklı oranlarda geri dönüşümlü beton agregası kullanılarak üretilen betonların erken yaş beton basınç dayanımlarını yüksek doğrulukla tahmin eden matematiksel model geliştirmektir. Bu amaçla toplamda 18 farklı beton serisi üretilmiş ve bu serilerin 1 ve 3 günlük beton basınç dayanımı değerlerinden faydalanılarak tepki yüzeyi metodu üzerinde istatistik analizleri yapılmıştır. Yapılan analizler sonucunda fc,1 gün ve fc,3 gün için matematiksel model geliştirilmiştir. Geliştirilen modelin belirlilik katsayılarının 0.99 olması bu modelin yüksek doğruluklu ve etkin bir şekilde kullanılabileceğini göstermiştir. Bu model yardımıyla erken yaş beton basınç dayanımı pratik ve yüksek doğruluklu bir şekilde belirlenebilmektedir. Böylece bu modelin kullanımının zaman ve maliyet açısından önemli faydalar sağlayacağı düşünülmektedir.

This study aims to develop a mathematical model that with high accuracy predicts the early-age concrete compressive strength of concretes produced using recycled concrete aggregate in different ratios. For this purpose, 18 different concrete series were produced, and statistical analyses were made on the response surface method using these series' 1- and 3-day concrete compressive strength values. As a result of the analysis, the mathematical model was developed for fc,1 day, and fc,3 days. The coefficient of determination belonging to the developed model is 0.99, which shows that this model can be used with high accuracy and efficiency. Using this model, the compressive strength of early-age concrete can be determined practically and with high accuracy. Thus, it is thought that using this model will provide significant benefits in terms of time and cost.
