İnorganik Metallerin Çimento harçlarının Antibakteriyel, Fiziksel ve Mekanik Özelliklere Etkisinin İncelenmesi

Abstract

Harçlar çevresel faktörlere maruz kalabilir ve bu durum sonrasında yapıda deformasyonlar gözlemlenebilir. Fiziksel ve yapısal özelliklere zarar veren bu deformasyonların inorganik metal kullanarak giderebileceği düşünülmektedir. Mevcut çalışmada, yukarıda belirtilen sorunları aşmak için farklı metal türleri (Kalay (Sn), Çinko (Zn)) kullanılarak çimento harçları üretilmiştir. Daha sonra fiziksel (yayılma, UPV), kimyasal (FTIR), mekanik (basınç ve eğilme), morfolojik (SEM-EDX) ve antibakteriyel özellikleri araştırılmıştır. Çalışmanın sonunda, C/S oranının değişmesi nedeniyle Si-O simetrik gerilmesinde kaymalar görüldü. Metaller matriste homojen bir şekilde dağılarak daha yüksek mekanik özellikler sağlamıştır. UPV değerleri metalin iletkenlik özelliği nedeniyle artarken, harcın işlenebilirliğini azaltmıştır. Ayrıca, Zn esaslı çimento harcı P. aeruginosa ATCC 2785'e karşı daha yüksek etkinlik göstermiştir. Yapılan çalışmanın literatüre ve endüstriye önemli katkı sağlayacağı düşünülmektedir.

Influence Inorganic Metals on Antibacterial, Physical and Mechanical Properties of Cement Mortar

Abstract

Mortars can be exposed to environmental factors and deformations can be observed in the structure after this circumstance. It is thought that using inorganic metal may handle these deformations which harm physical and structural properties. In the present study, cement mortars were produced using different types of metals ((Tin (Sn), Zinc (Zn)) to overcome the abovementioned problem. Then, the physical (flowability, UPV), chemical (FTIR), mechanical (compressive and flexural), morphological (SEM-EDX), and antibacterial properties have been investigated. At the end of the study, minor shifts were seen in the Si-O symmetric stretching due to alteration of the C/S ratio. Metals enabled higher mechanical properties by dispersing homogeneously in the matrix. UPV values increased because of metal’s conductivity property whereas those metals make it decrease flowability. Also, cement mortar having Zn revealed a higher efficiency against P. aeruginosa ATCC 2785. It is thought that the study will contribute significantly to the literature and the industry.
