AB  - Bu çalışmada, son yıllarda yapı malzemeleri üretiminde sıklıkla kullanılan nano silikanın çimento esaslı harçların dayanıklılık özellerine etkisi araştırılmıştır. %1, %2 ve %4 oranlarında nano silika ilavesi ile çimento harçları üretilmiş; yayılma, kılcal su emme, basınç dayanımı gelişimi ve klorür geçirimliliği incelenmiştir. Nano silikalı karışımların zamana bağlı davranışını ortaya koymak için testler 28. ve 90. günlerde tekrar edilmiştir. Çalışma sonucunda, nano silikanın işlenebilme özelliklerini olumsuz etkilediği ancak sertleşmiş hal özelliklerini iyileştirdiği görülmüştür. Artan nano silika miktarı ile boşluk oranı ve klorür geçirimliliği azalırken basınç dayanımının arttığı belirlenmiştir. Nano malzemenin, çimento matrisi içerisinde homojen dağılmasının sağlanması koşulu ile %4 gibi yüksek bir oranda nano silika ilavesinin mümkün olduğu ve dayanıklılık özelliklerini önemli ölçüde iyileştirdiği vurgulanmıştır.

N2  - In this study, the influence of nano silica, used in the production of construction materials in recent years, on the durability properties of cement-based mortar has been investigated. Mortars with nano silica additions at 1%, 2%, and 4% ratios were produced; workability, water absorption, compressive strength development, and chloride permeability were examined. Tests were repeated on the 28th and 90th days to reveal the time-dependent behavior of nano-silica-containing mixtures. As a result of the study, it was observed that nano silica adversely affected the workability properties but improved the hardened state properties of mortars. It was determined that with increasing nano silica content, the void ratio and chloride permeability decreased while the compressive strength increased. It was emphasized that with the condition of ensuring the homogeneous distribution of the nano material within the cement matrix, a high addition of nano silica such as 4% is possible and significantly improves the durability properties.
