Bu çalışmada, tarımsal atık malzemesi olan Pirinç kabuğu külü, çimento yerine ağırlıkça %0, %2, 4%, 6%, 8%, 10%, ve %15 oranlarda kullanılarak toplam 7 farklı bileşime sahip harç numunesi üretilmiştir. Üretilen harç numuneleri üzerinde 28, 56 ve 90 günlük kür süreleri sonunda basınç dayanımı tespitinin yanında 56 günlük kür sonunda donma-çözülme ve ultrasonik hız tayini deneyleri de yapılmıştır. Çalışmada kullanılan bütün karışımlarda Su/Bağlayıcı oranı 0.50 oranında sabit tutulmuştur. Üretilen harç numunelerine ait sonuçlar değerlendirildiğinde %8 Pirinç kabuğu külü ikameli harçların daha yüksek dayanım ve dayanıklılık sonuçları verdiği tespit edilmiştir.

Investigation of Strength and Durability Properties of Mortars with Rice Husk Ash Additive

Öz

In this study, a total of 7 different composition mortar samples were produced by using Rice husk ash, which is an agricultural waste material, instead of Cement at 0%, 2%, 4%, 6%, 8%, 10% and 15% by weight. Freezing-thawing and Ultrasonic velocity determination experiments were performed on the produced mortar samples as well as the compressive strength determination at the end of the curing periods of 28, 56 and 90 days. Water/Binder ratio was kept constant at 0.50 in all mixtures used in the study. When the results of the mortar samples were evaluated, it was determined that the mortars with 8% Rice husk ash substitution gave higher strength and durability results.
