İGNİMBİRİTLERE AİT FARKLI TANE BÜYÜKLÜĞÜNE SAHİP TAŞ TOZU VE EPOKSİ REÇİNE ESASLI KOMPOZİTLERİN TUZ ETKİSİNE BAĞLI HASARLARA KARŞI KORUMA POTANSİYELİNİN İNCELENMESİ

Öz

Yapıların inşasında kullanılan taşlar nem oranı, tuz kristalleşmesi, iklimsel etkiler, hava kirliliği ve biyolojik faktörler gibi nedenlerden dolayı bozulmaya uğramaktadır. Tuz kristalleşmesi taşların bozulmasında en etkili faktörlerden birisidir. Taşlarda tuz kristalleşmesi yoluyla; çürümeler, çatlaklar ve aşınmalar gibi tahribatlara yol açmaktadır. Bu çalışmada, ignimbirit taş tozu (İTT) ve epoksi reçine (ER) esaslı kompozitlerin, yapı taşlarında tuz kristalleşmesi hasarlarına karşı onarımında kullanılması amaçlanmaktadır. Bu amaçla, Nevşehir ili ve çevresinden çıkarılan, yapıların inşaatında kullanılan ignimbiritlere ait farklı tane büyüklüğüne (63 μm, 150 μm, 250 μm, 500 μm, 1000 μm) sahip taş tozu ve matriks olarak epoksi reçine ile kompozitler hazırlanmıştır. Kompozitlerin tuz etkisine bağlı hasarlara karşı koruma potansiyelinin incelenmesi için; su emme, görünür yoğunluk, açık gözeneklilik ve tuz kristalleşmesi deneyleri yapılmıştır. Deney sonucuna göre, % 70 oranında <63 μm büyüklüğüne sahip İTT örneğinin, diğer örneklere göre tuz etkisine karşı daha dirençli olduğu belirlenmiştir. Bu kompozit, yapı taşlarının tuz etkisine karşı korunmasında etkili olduğundan, yapıların tuz kristalizasyonuyla oluşan çürümüş kısımlarının onarımı için harç enjeksiyon uygulamasıyla kullanılabileceği sonucuna varılmıştır.

INVESTIGATION OF THE PROTECTION POTENTIAL OF STONE POWDER WITH DIFFERENT GRAIN SIZES BELONGING TO IGNIMBRITES AND EPOXY RESIN BASED OF COMPOSITES AGAINST DAMAGE DUE TO SALT EFFECT

Abstract

The stones used in the construction of buildings are subject to deterioration due to reasons such as humidity, salt crystallization, climatic effects, air pollution and biological factors. Salt crystallization is one of the most effective factors in the deterioration of stones. It causes damages such as decay, cracks and abrasions in stones through salt crystallization. This study aims to use ignimbrite stone powder (ISP) and epoxy resin (ER) based composites in the repair of salt crystallization damages in building stones. For this purpose, composites were prepared with stone powder of different grain sizes (63 μm, 150 μm, 250 μm, 500 μm, 1000 μm) belonging to ignimbrites extracted from Nevsehir province and its surroundings and used in the construction of structures, and epoxy resin as matrix. To investigate the protection potential of the composites against salt-induced damage; water absorption, apparent density, open porosity and salt crystallization experiments were carried out. According to the experiment results, it was determined that the ISP sample with a size of <63 μm at 70 wt.% was more resistant to salt effects than other samples. Since this composite is effective in protecting building stones against salt effects, it has been concluded that it can be used with mortar injection application for the repair of decayed parts of structures caused by salt crystallization.
