NANO SİLİKA’NIN BETON BASINÇ DAYANIMINA ETKİSİNİN İNCELENMESİ

Öz

Bu çalışmada Nano SiO2’nin betonların basınç dayanımına olan etkisi çok yönlü olarak incelenmiştir. Dünyada en çok kullanılan yapı malzemesi olan beton, gün geçtikçe gelişmekte ve yenilenmektedir. Bilimsel çalışmalar çimentonun yerini alacak alternatifler ararken, bir yandan da çimentonun performansını geliştirmek için yeni katkılar üretmektedir. Nano Silika (SiO₂) betonun çeşitli özelliklerini iyileştirmek amacıyla beton bünyesinde çimentoyla ikame edilerek denenmekte, özellikle yüksek dayanımlı betonlarda matris özellikleri üzerinde çeşitli etkiler yapmaktadır.
