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.
