Na2O, silika modülü, su/bağlayıcı oranı ve yaşlanmanın cüruf tabanlı geopolimerlerin basınç mukavemetinde olan etkileri

Öz

Geopolimerler, Portland çimentosu ve Portland çimentolu betonlar için puzolanların aktivasyonundan üretilen alternatif bağlayıcılardır. Malzeme özelliklerinin güçlendirilmesi, çevre dostu olması ve çimento yerine üretilebilmesi için bu çalışmada ferrokrom cürufu tabanlı geopolimerinin mekanik özellikleri araştırılmıştır. Bu çalışmada, ferrokrom cürufunu aktive edebilmek için, Na2O yüzdesi, silika modülü ve su/bağlayıcı oranlarına göre dokuz farklı seride geopolimer karışımı hazırlanmıştır. Test sonuçları, üretilen geopolimerlerin basınç dayanımının yeterince yüksek olduğunu ve yapısal bir malzeme olarak kullanılabileceğini göstermiştir.

The effects of Na2O, silica modulus, water/binder and aging on compressive strength of ferrochrome slag based geopolymers

Öz

Geopolymers are alternatives for ordinary Portland cement concrete that are made from pozzolans activation. To enhance material greenness and produce alternative binders as a geopolymer, mechanical properties of  ferrochrome slag geopolymer has been investigated in this study and to identify the best geopolymer mix ratios, varying silica modulus , water/binder and Na₂O content have been investigated. Hence nine series of geopolymer pastes differing in Na₂O content, silica modulus and w/b ratios were manufactured to activating ferrochrome slag in this study. Test results indicated that the produced geopolymers compressive strength were high enough and can be used as a structural material.
