Bu çalışmada, C sınıfı uçucu kül ÜK ve silis dumanı SD ‘den üretilen kendiliğinden yerleşen harçların KYH mukavemet özelliklerini ve dayanıklılıklarını araştırmayı amaçlamaktadır. KYH ‘ler, Portland çimentosu yerine ağırlıkça % 10,% 20 ve% 30 oranında C sınıfı uçucu kül FA ve % 6,% 10,% 14 oranında silika dumanı ağırlıkça ikame ederek ÜK ve SD’ lı ikili karışımlar üretilmiştir. Su/bağlayıcı s/b oranı 0.37 ila 0.48 arasında tutulmuştur. 7 farklı karışım toplam bağlayıcı miktarı 630 kg/m3 olan KYH ın taze ve sertleştirilmiş koşullarda davranışını incelemek için hazırlanmıştır. UK ve SD içeren KYH’ların taze özelliklerini ölçmek için mini slump çapı, viskozite ve mini V-huni akış süresi testleri gerçekleştirilmiştir. Basınç ve çekme dayanımlarını incelemek için 40x40x160 mm boyutunda numuneler 7, 28 ve 180 günlük suda kür edilmiş ve test edilmiştir. Durabilite özelliklerini incelemek için 50 mm boyutunda küp numuneler üretilmiş ve 28 gün suda kür edildikten sonra ve porozite ve görünür yoğunluk değerleri bulunmuştur. UK den üretilmiş ikili karışımlarının basınç dayanımının UK içeriği arttıkça azaldığını gözlenmiştir.%10 ikameli UK den üretilmiş nümünler 180 günlük kür sonucunda en yüksek çekme mukavemetine ulaştığı görülmüştür

This paper aims to investigate the strength properties and durability of self-compacting mortars SCMs produced from C class fly ash FA and silica fume SF as mineral admixtures. SCMs were produced from the binary mixes of FA and SF by replacing Portland cement with 10%, 20%, and 30% by weight of C class fly ash FA and 6%, 10%, 14% by weight of silica fume SF . The water-to-binder w/b ratio ranges from 0.37 to 0.48. A sum of 7 different mixtures with 630 kg/m3 binder were prepared to observe SCMs behavior in fresh and hardened conditions. Mini slump flow diameter, viscosity and mini V-funnel flow time tests were performed to assess the fresh properties of SCMs containing FA and SF. Specimens of 40x40x160 mm were produced and cured at the age of 7, 28 and 180-day for compressive and tensile strength tests and 50 mm cube specimens were prepared and cured at 28 days for durability tests porosity and density . The results indicated that the compressive strength of binary mixes of FA reduces as the content of FA increases. Binary mix of SF10 reaches the highest tensile strength at the age of 180 days.
