Çimento Kompozitlerinin Donma/Çözülme Direnci Üzerinde Kendi Kendini İyileştiren Kimyasal Katkı Maddelerinin Etkinliği
Öz
Betonun kendi kendini iyileştirmesi, malzemenin mevcut çatlakları iyileştirerek kendini yenileme sürecidir Bu ya otojen/doğal kendi kendini iyileştirme ile ya da otonom/yapay kendi kendini iyileştirme ile olabilir. Otonom kendi kendini iyileştirme teknikleri arasında kristalli hidrofilik katkı maddelerinin kullanımı, bakteriyel yöntem ve mikroenkapsülasyon yöntemi yer alır. İçsel çatlamalar, donma/çözülme döngüleri tarafından meydana gelen hasar biçimlerinden biri olduğundan, bu makalenin amacı, kristal hidrofilik katkı maddesi ve mikrokapsüller gibi yapay kendi kendini iyileştirme tekniklerinin çimento kompozitlerinin donma/çözülme direnci üzerindeki etkinliğini değerlendirmektir. Bu amaçla, şahit harç karışımı, kristal hidrofilik katkılı harç karışımı ve toluen diizosiyanat (TDI) mikrokapsüllü harç karışımı (her iki katkı da çimento ağırlığına göre 2% oranında eklenmiştir) hazırlanmıştır. Sertleşmiş harç numuneleri CEN/TS 12390-9:2006 'ya göre donma/çözülme döngülerine tabi tutulmuş ve donma/çözülme döngülerinden kaynaklanan tufal malzeme miktarı ölçülmüştür. Kendi kendini iyileştiren katkı maddelerine sahip her iki harç karışımında tufal malzeme miktarının, burada kullanılan kendi kendini iyileştiren kimyasal katkı maddelerinin çimento kompozitlerinin donma/çözülme döngülerine karşı direncini artırabileceğini gösteren referans harç karışımına göre, daha düşük olduğu görülmüştür.

The paper compares the effectiveness of two self-healing chemical additives: crystalline hydrophilic additive and toluene diisocyanate (TDI) microcapsules, on the freeze/thaw resistance of cement composites. The reference mortar mixture, the mortar mixture with crystalline hydrophilic additive as well as the mortar mixture with TDI microcapsules (both additives added in 2% by cement weight) were prepared. Hardened mortar samples are subjected to freezing and thawing cycles according to CEN/TS 12390-9:2006. The testing results indicate that self-healing chemical additives used here could improve resistance of the cement composites to freeze/thaw cycles.
