Abstract

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.

Keywords
