ÇİMENTO YERİNE KISMİ AHŞAP TABAN KÜLÜ İÇEREN HARÇLARIN MEKANİK ÖZELLİKLERİ

Öz

Portland çimentosu (PÇ) üretimi sırasında atmosfere salınan karbondioksit (CO2), küresel ısınmaya neden olan önemli faktörlerden biridir. Bu nedenle PÇ tüketimini azaltmak için farklı malzemeler üzerinde çalışmalar yapılmaktadır. Bu çalışmada, değişkenlerin (ahşap taban külü (ATK) oranı ve numune yaşı) tepki değişkenleri (ultrasonik atımlı dalga hızı, eğilmede çekme ve basma dayanımı) üzerindeki etki düzeyleri araştırılmıştır. Harç numuneleri; PÇ, ATK, CEN standart kum ve distile su kullanılarak üretilmiştir. Üretilen numuneler, deney gününe kadar suda kür işlemine tabi tutulmuştur. ATK ilave oranları bağlayıcı ağırlığınca %0, %5, %10, %20, %35 ve %50’dir. Sonuç olarak, optimum ATK kullanım oranının %5 olduğu tespit edilmiştir. Ek olarak, varyans analizi (ANOVA) ile tepki değişkenlerinin R2 değerlerinin yüksek olduğu (ultrasonik atımlı dalga hızı; 0.8925, eğilme dayanımı; 0.9356, basınç dayanımı; 0.9404) bulunmuştur. Bu durum, modellerin yüksek bir korelasyona sahip olduğunu göstermektedir. Ayrıca modellerdeki terimler, tepki değişkenleri üzerinde önemli bir etkiye sahiptir.

MECHANICAL PROPERTIES OF MORTARS CONTAINING PARTIALLY WOOD BOTTOM ASH INSTEAD OF CEMENT

Abstract

Carbon dioxide (CO2) released into the atmosphere during the production of Portland cement (PC) is one of the important factors causing global warming. Therefore, studies are carried out on different materials to reduce PC consumption. The effect levels of the wood bottom ash (WBA) ratio and specimen age on the response variables (compressive strength, flexural strength, and ultrasonic pulse velocity) were investigated in this study. Mortar specimens were produced using PC, WBA, CEN standard sand, and distilled water. The produced specimens were cured in water until the test day. WBA ratios are 0%, 5%, 10%, 20%, 35% and 50% by weight of binder. As a result, it was determined that the optimum WBA ratio was 5%. In addition, R2 values of response variables were found to be high (ultrasonic pulsed wave velocity; 0.8925, flexural strength; 0.9356, compressive strength; 0.9404) by analysis of variance (ANOVA). This shows that the models have a high correlation. Moreover, the terms added to the models have a significant effect on the responses.
