Cementitious composites
have become very widely used in building materials in all over the world.
However, deterioration is inevitable since the initiation of the service life
of structure. Then, labor and expenditure based maintenance and
repair works become necessary. Therefore, self-healing of the cementitious
composites deteriorated due to environmental effects has great importance. The
self-healing behavior of cementitious composites have been considered and
examined by many researchers for a long time. Especially, self-healing was be more attractive method for ECC due to its sequential development of multiple cracks instead of continuous widening
of one localized crack in concrete.

MİKROMEKANİK OLARAK TASARLANMIŞ ÇİMENTO ESASLI KOMPOZİTİN (ECC) KENDİLİĞİNDEN İYİLEŞMESİ

Öz

Tüm dünyada, çimento esaslı kompozitler çok
yaygın bir şekilde kullanılan yapı malzemeleri haline gelmiştir. Bununla
birlikte, bu malzemelerde yapının servis ömrünün başlangıcından itibaren
bozulma kaçınılmazdır. Daha sonra, çoğunlukla işçilik ve harcama yoğunluğu olan
bakım ve onarım işleri söz konusu olmaktadır. Bu sebeple, çevresel etkilerle
bozulan çimento esaslı kompozitlerin kendiliğinden iyileşmesi büyük bir öneme
sahiptir. Çimento esaslı kompozitlerde kendiliğinden iyileşme olayı, uzun
zamandır birçok araştırmacı tarafından dikkate alınmakta ve incelenmektedir.
Özellikle, ECC’de lokal olarak sürekli genişleyen bir çatlak yerine betonda
birbirini izleyen çoklu çatlak oluşumu, kendiliğinden iyileşmeyi bu alanda daha
cazip bir yöntem haline getirmektedir.
