Abstract:

 It is known that various fibers were used as additives in the original mortars of historical buildings and these fibers improved the physical and mechanical properties of the mortars. Today, the need for sustainable nanomaterials in building materials has led researchers to investigate nanocelluloses. In this study, nanofiber cellulose NFS incorporated lime-based grouts were produced and the fresh and hardened state properties of the materials were examined. The main purpose of the study is to develop a new lime-based grout that can be used for consolidation of historical buildings. According to the test results, although the addition of NFS negatively affects the fresh state properties, it significantly increases the mechanical properties and shrinkage resistance. It has also been observed that NFS works as a natural viscosity modifier and can be preferred over synthetic additives.

 Tarihi yapılardaki özgün harçlarda çeşitli liflerin ilave malzeme olarak kullanıldığı ve bu liflerin harçların fiziksel ve mekanik özelliklerini geliştirdiği bilinmektedir. Günümüzde yapı malzemelerinde sürdürülebilir nano malzemelere duyulan ihtiyaç araştırmacıları nanoselülozlara yönlendirmiştir. Bu çalışmada kireç esaslı ve nanofiber selüloz NFS katkılı enjeksiyon malzemeleri üretilerek malzemelerin taze ve sertleşmiş hal özellikleri incelenmiştir. Çalışmanın amacı; tarihi yapıların onarımında ve güçlendirilmesinde kullanılabilecek yeni bir kireç esaslı enjeksiyon malzemesi geliştirmektir. Deney sonuçlarına göre NFS ilavesi akışkanlık ve penetrasyon özelliklerini olumsuz etkilese de mekanik özellikleri ve rötre direncini ciddi oranda artırmaktadır. Ayrıca NFSnin, doğal viskozite düzenleyici olarak çalıştığı ve sentetik katkı maddeleri yerine tercih edilebileceği görülmüştür.
