Abstract

In this study, the properties of the cement mortars containing zeolite + silica fume as Portland cement replacement materials were investigated, and the results obtained were compared with the control mortar. In the experiments, sand and water quantities were kept constant. Zeolite was used at 0%, 5%, 10%, 15%, 20% and 30% replacement by weight of cement in the mortars while 10% of silica fume was added into the mixtures. Water demand, setting times, soundness, compressive and flexural strength, water absorption, porosity, dry unit weight, abrasion resistance and carbonation depth of the mortars was determined. The findings obtained showed that zeolite and silica fume used as replacement materials for cement improved the properties of the cement mortar, exhibiting a better performance than the control mortar according to the tests performed.

Özet

Çalışmada, ikame malzemesi olarak zeolit+silis dumanı içeren çimento harçlarının, fiziksel, mekanik ve durabilite özellikleri araştırılmış, elde edilen sonuçlar, kontrol harcınınki ile kıyaslanmıştır. Kum ve su miktarlarının sabit tutulduğu deneylerde %10 oranında silis dumanı sabit kalmak kaydıyla ağırlıkça %0, %5, %10, %15, %20 ve %30 oranlarında değişen zeolit yer değişimleri ile üçlü harç karışımları elde edilmiştir. Karışımların, su ihtiyacı, priz süresi, hacim genleşmesi, eğilme dayanımı, basınç dayanımı, su emme, porozite, kuru birim ağırlık, aşınma direnci ve karbonatlaşma derinliği ölçülmüştür. Yürütülen deneyler kapsamında elde edilen bulgular, çimento yerine ikame edilen zeolit ve silis dumanının, harcın özelliklerini iyileştirerek kontrol harcına göre daha iyi sonuçlar verdiğini göstermiştir.
