Investigation of the Engineering Properties of Mortars with Calcined Natural Zeolite Replacement

Öz

In this study, the physical and mechanical properties of mortar specimens prepared by substituting natural and calcined forms of zeolite, abundant in reserves in our country, for cement have been investigated. In this study, specimens measuring 50x50x50 mm were produced by substituting 15% natural and calcined zeolite for cement. On the prepared specimens, compressive strength tests at 3, 7, 28, and 90 days were conducted; additionally, capillary water absorption, ultrasonic pulse velocity, wetting-drying tests, and microstructure properties were examined using SEM analyses. According to the results obtained from the study, it was observed that calcined zeolite, when substituted for cement, improved the properties of the mortar and yielded more favorable results compared to the control mortar. It has been observed that mortars containing calcined zeolite are more impermeable compared to the control mortars and provide more favorable results in terms of durability.

Kalsine Edilmiş Doğal Zeolit İkameli Harçların Mühendislik Özelliklerinin İncelenmesi

Öz

Bu çalışmada, ülkemizde bol miktarda bulunan zeolit rezervlerinin, doğal ve kalsine edilmiş hallerinin çimento yerine ikame edilerek hazırlanan harç numunelerinin fiziksel ve mekanik özellikleri araştırılmıştır. Çalışmada, %15 oranında doğal ve kalsine edilmiş zeolit, çimento yerine ikame edilerek 50x50x50 mm boyutlarında numuneler üretilmiştir. Hazırlanan numuneler üzerinde 3, 7, 28 ve 90 günlük basınç dayanımı deneyleri; ayrıca kapiler su emme, ultrasonik geçiş hızı, ıslanma kuruma deneyleri ve mikroyapı özelliklerini incelemek amacıyla SEM analizleri yapılmıştır. Çalışmadan elde edilen sonuçlara göre, çimento yerine ikame edilen kalsine zeolit, harcın özelliklerini iyileştirdiği ve kontrol harcına göre daha olumlu sonuçlar verdiği gözlemlenmiştir. Kalsine edilmiş zeolit ikameli harçların kontrol harçlarına kıyasla daha geçirimsiz olduğu ve dayanıklılık açısından daha olumlu sonuçlar verdiği tespit edilmiştir.
