Abstract

Bu çalışmada, harç özelikleri üzerine atık lastik külü ve uçucu külün uzun süreli etkisi

araştırılmıştır. Lastik küllü, uçucu küllü-lastik küllü ve uçucu küllü olmak üzere üç farklı grup

numune üretilmiştir. Lastik külü ve uçucu kül miktarlarının artması numunelerin mekanik

özeliklerini, ağırlıkça su emme, ağırlık kaybı ve donma-çözülme sonuçlarını olumsuz etkilemiştir. Bu

deneyler sonucunda en iyi sonuçlar çimento yerine % 10 lastik külü kullanılan numunelerde

görülmüştür. Atık lastiklerin taşınması ve depolanması hem oldukça maliyetlidir hem de çevre

kirliliğine neden olmaktadır. Çalışma sonucunda atık lastiklerin hafif harç yapımında kullanılması

önerilmektedir.

Properties Of Rubber Ash Mortars

Abstract

In this study, the long-term effect of waste tire rubber ash and fly ash on the properties

of mortars was investigated. Experimental results have shown that the mechanical properties, water

absorption by weight, loss in weight and freezing-thawing damage properties of the specimens have

been affected negatively due to the increase in amounts of tire rubber ash and fly ash. After these

experiments, it was observed that the best results were obtained from mortars produced by using 10

% of tire rubber ash instead of cement by weight. The transportation and storage of waste tires costs

significantly and causes detrimental effects on environmental regime. Consequently it is

recommended to utilize tire rubber ash in lightweight mortar production.

Keywords
