Bu çalışmada yüksek fırın cürufu kullanılarak üretilen alkalilerle aktivite edilmiş harç numunelerde grafit tozu katkısının mekanik özellikler ve elektrik iletkenliğine etkisi araştırılmıştır. Harç numunelerin hazırlanmasında bağlayıcı oranın ağırlıkça %0-%0,5-%1-%2 ve %4 oranında, (75) mikron boyutunda grafit tozu ikame edilmiştir. Yüksek Fırın cürufu ile üretilen harç numunelerde aktivatör olarak sodyum hidroksit ve sodyum silikat kullanılmış ve numuneler 24 saat 110⁰C’de ısıl küre tabi tutulmuştur. Kür süresini tamamlayan tüm harç numunelerin işlenebilirlik, birim ağırlık, elektriksel iletkenlik, eğilme ve basınç dayanımları belirlenmiştir. Ayrıca, alkalilerle aktivite edilmiş çimentolu sistemin de en iyi sonuçları veren numunelerin su emme ve boşluk oranlarını belirleyen deneyler yapılmıştır. Elde edilen sonuçlar; grafit tozunun alkalilerle aktivite edilmiş harç numunelerde %1 takviye oranında işlenebilirliğin iyileştiği, %1’in üzerindeki oranlarda olumsuz etki yaptığı görülmüştür. %1 grafit tozu katkısı eğilme ve basınç dayanımlarına pozitif katkı sağlarken, %4 grafit tozu takviyesi ise en yüksek elektriksel iletkenliği sağladığı anlaşılmıştır.

In this study, the effect of graphite powder additive on mechanical properties and electrical conductivity of alkali-activated mortar samples produced using blast furnace slag was investigated. In the preparation of the mortar samples, graphite powder in (75) micron size was substituted at a rate of 0%-0.5-1%, 2% and 4% by weight of the binder. Sodium hydroxide and sodium silicate were used as activators in the mortar samples produced with Blast Furnace slag, and the samples were thermal cured at 110⁰C for 24 hours. Workability, unit weight, electrical conductivity, tendencies and compressive strength of all mortar samples that completed the curing period were determined. In addition, experiments were carried out to determine the water absorption and void ratios of the samples that gave the best results in the cementitious system activated with alkalis. The results obtained showed that the workability of the graphite powder was improved at 1% reinforcement rate in the mortar samples activated with alkalis, and it had a negative effect at the rates above 1%. It was understood that 1% graphite powder additive contributed positively to flexural and compressive strengths, while 4% graphite powder additive contributed provided the highest electrical conductivity.
